Training - Why Should You Get A Better Fan?

In 2015 and this year I trained basically 100% indoors, going outdoors only for races or a few event rides (the latter in 2015 only). My last regular outdoor training ride was around Christmas 2014 when we had unseasonably warm temperatures here in northeastern US.

Indoor Training Advantages

I've always trained indoors throughout the year, in the winter to avoid the cold/chill, but even in the summer, usually to escape the heat/humidity outside. This has been the case for about 25-30 years. Training indoors is great for a number of reasons, like road safety, no scheduling problems if you encounter a mechanical, immediate parts/tools availability for said mechanical, immediate water/food availability, etc. For about 10 years I trained inside the bike shop so I really had any and every part available if something happened. I've done outside rides only to puncture at a critical time, like on a ride where I gave myself virtually no time cushion to pick up Junior from daycare. Although I rode harder than I thought possible it was an irresponsible way to motivate myself.

Indoor Training Challenges

Training indoors is tough for a number of reasons. The absolutely most significant thing with indoor training is that it's simply harder than riding outside. No one can really pinpoint exactly why but this post offers some possible suggestions. Basically it suggests that not being able to coast, not being able to rock the bike, and less external stimuli as factors that make indoor training harder than training outside.

However the main one most people cite when talking about training indoors is boredom. Nowadays, with all the tech available, there's quite a bit of distraction available to combat this problem. I find that watching bike DVDs, using Zwift, and listening to music make time fly on the trainer.

A dominant Race Across America rider, Lon Haldeman, defined the anti-thesis of a bored indoor rider. He would ride rollers in the dark to condition himself to riding through a dark night in the middle of nowhere. Although I don't turn out the lights and I generally don't ride rollers, I still find myself regularly reverting to riding with my eyes closed, particularly when pushing hard. I count pedal revolutions, focus on maintaining a consistent pedal stroke, and open my eyes to do a time/effort check.

Another indoor challenge is learning and conditioning to ride out of the saddle. Due to the nature of trainers and rollers it's hard to rock the bike out of the saddle (Kinetic Rock N Roll notwithstanding). For me this is significant since I simply cannot sprint effectively without being out of the saddle. I admit that I'm in the final stages of doing a very low buck DIY Rock N Roll using a converted CycleOps Fluid trainer frame (yikes, I started that three years ago?). If that works out I'll post about it, otherwise it was all just an exercise in experimentation for me.

Direct drive trainers tackle the problem of tire slippage. It's significant when making huge efforts. I'm not quite strong enough to regularly slip tires on my trainer/s but there are riders significantly stronger than me that probably have major tire slippage. Such a trainer replaces your whole rear wheel - ultimately you end up putting your bike's chain on the trainer's cassette. By eliminating the tire-roller interface a direct drive trainer makes the system virtually slip-free.

A "smart" trainer is the ultimate for indoor training. "Smart" trainers use software inputs to adjust resistance, so, for example, if you're using a program like Zwift and you're on an uphill, a smart trainer will increase resistance. In order to make it up the hill you'll have to shift into lower gears. With a regular trainer you have to shift into higher gears in order to increase resistance. Smart trainers should engage you a bit more, due to the fact that you'll need to shift gears to react to virtual terrain changes.

A long time ago I got to use a smart trainer, something called a VeloDyne. It was really engaging, really motivating. It was a bit hard as it didn't coast well, making the downhills the hardest part of any route. There was also not much in terms of "courses". I think the 1984 Olympic RR was one of the courses, I think also Morgul-Bismark of Coors Classic fame, but one could not import a course, nor could one make their own. I might have a picture of it from my shop days but I don't know at this point. I did have an adventure delivering one though.

For all the indoor training I do I haven't been able to justify purchasing a smart trainer or a rocking one. Zwift started to change my mind on direct drive and active trainers, but at the moment buying such a trainer is simply out of the question.

Indoor Training Cooling

Finally indoor training is hard because it's hard to cool off.

When you work hard you generate excess heat energy. Your body tries to get rid of that heat energy, mainly by expanding blood vessels near the skin surface (so you get flushed, your veins pop, etc) and by sweating. Sweat gets rid of heat through evaporation. When sweat evaporates it must absorb heat energy - if the sweat doesn't evaporate then it won't do much good in removing heat.

For sweat to evaporate it needs two things - air and some dryness. If your sweat has no air volume around it then it can't evaporate. For example if you wrapped yourself in Saran Wrap you'd be mighty hot after a short time. On the other hand if you were in an indoor stadium or concert hall, you'd have a lot of air volume. When I had the shop with 20 foot ceilings and a 70'x25' floor foot print, I had a gazillion feet of air volume (okay, it was 20x70x25 so 35,000 cubic feet of air). With smaller areas you need to move air around so that you're introducing new air to your trainer area. A powerful fan works well for this, allowing you to move air around quickly.

Sweat can't evaporate if it's too humid. If you're in 99% humidity air then the air is basically saturated. Your sweat won't really evaporate and therefore it won't really cool you down. You'll feel like you're taking a hot shower. Air conditioning helps, since it dries the air. A dehumidifier is good also, although it heats the air while it dries it, making it a bit touch and go if the house is already warm. In the shop example above I had 35,000 of air conditioned goodness so even in the middle of a heat wave it was downright pleasant to ride indoors for an hour or two at a time. We even had "group indoor rides" with maybe 6 or 8 riders, without any problems with too much humidity.

Remember, air volume and humidity.

Indoor Training Set Ups

When I see someone else's trainer set up I always look at a number of things usually obvious by the picture.

1. Fan, like its size/velocity.
2. Air Volume, like how much air volume appears to be there.
3. Air temperature, like does it look like the rider is on a trainer in their garage with the door open during a snow storm?

Those three factors - air velocity, air volume, and air temperature - really affect how you'll feel on the trainer.

There's a fourth factor but it's hard to guess at, although it's often related to air volume. The mystery factor is air humidity. I'll put it in the list below.

4. Humidity

If I see central AC vents or a window AC unit or a cold/wintry background then I'm guessing the humidity is under control. If I see a dehumidifier, if I see five towels draped over the bike and nearby furniture and a puddle of water under the bike then I'm guessing the humidity is a bit out of control.

The other day (okay, the other month) I saw a picture of the local hero pro on his trainer It looks like a home decor ad, if you ask me, because it looks so neat and tidy:

Note the fan on the floor.

(Let me put in this disclaimer right away. In my world 200 watts is a hard effort. 450 watts is basically a max 60 second effort. For someone like Ben he does 450w average for a long time, like an hour at the beginning of a long day of racing. This is based on the fact that he posted that it took 450w avg for an hour just to make the second laughing group at some stage in the Tour of CA this year. What I mean is that my recommendations may not hold water if you're a super human and don't generate much heat cranking out 400 watts. Maybe you don't even break a sweat at 400w.)

Anywho...

When I saw Ben's picture above I subconsciously went down my list. I'll skip #1 for now and start with #2, Air Volume. It looks fine - there's so much ceiling above him that someone could take this very stylish picture.

#3 Air temperature I'm guessing is okay since it's June and the windows are closed. This could be an indicator of air conditioning.

#4 Humidity... related to air conditioning, air conditioning would make humidity a non-issue.

The only thing left is #1, air velocity. He's using what appears to be the ubiquitous Lasko 20" box fan. Set on the floor it blows cooler air up at his head/upper torso, ideal for cooling off a working rider. It's a decent fan for moving air around - I should know, I think we have four in the house. We use one dinky little window type AC unit to cool our 1500 sf house. The box fans help move the air around so we don't have one icy cold room with the rest of the house sweltering in heat; instead we have one chilly room and an otherwise comfortably dry and cool house. Other than the low thrumming of fans in the background and the somewhat MacGyver looking fans set up around the house the system works well.

The ubiquitous Lasko box fan is rated at "up to" 2500 CFM, or 2500 cubic feet per minute. That's on high. I thought I read somewhere that low is 800-1000 CFM (I think when I worked at a place that sold such fans) but I can't verify that.

When I see these fans in front of trainers or treadmills I wonder how the person can possibly stay cool. Okay, in the winter, in an unheated basement, it's sort of reasonable since you may not need much air velocity at all. But when it's even sort of warm you really need a lot of air flow to evaporate your sweat to cool you down. If there's no evaporation happening then there's really no cooling off happening either. That's why a super humid 95 degrees can be so much tougher than a very dry 105 degrees.

My set up isn't quite as neat at the one above, as evidenced by the picture below. However there is one key element in my set up: a very strong fan.

You might be able to find the fan on the floor amongst all the clutter.
It's a 20" Hamilton high velocity fan.

Air volume is sort of low because the bike room is in our basement. Worse, in order to keep the cats out of all sorts of human-inaccessible nooks and crannies, we have to keep the door shut to the bike room half of the basement. For the trainer room and the bike "shop" room I have two small rooms for air volume. Two wall mounted vent grilles allow air to travel between the bike half of the basement and the regular half. I have two fans permanently pushing air around the bike room and out of one of the vent grills so I'm guessing that the air probably gets cycled once daily at most.

Not only that, because of all sorts of reasons I can't leave the door at the top of the stairs to the basement itself open except for late at night so there's very little air flow into for most of the day - it's whatever seeps around the door along with about a 5"x5" cat door (we removed the flap so it's always open). Therefore the basement air itself doesn't get "refreshed" very frequently. At night in warmer weather I use one of our Lasko box fans to push air into the basement, allowing the hotter air down there to travel up the ceiling into the first floor.

Very low air volume cat door in our door to the basement stairs.
This doesn't bode well for air exchange between the main house and the basement.

In the winter the furnace naturally creates circulation, heated air rising to the first floor, cooler air sinking into the basement. It ends up the basement is pretty warm in the winter so it works out.

For air temperature the bike room is fine in the winter, typically 45-65 degrees F. In warmer weather it gets a bit hot, like 75-80 degrees F.

Humidity is all over the board. In the winter it's about 35-45%, ideal for indoor training. Sweat evaporates quickly and the room doesn't feel like a sauna. In the summer about 70-80%; that's not that great, I get sweat running down my face, I have to use a towel to keep my eyes clear, and, probably most significantly, I'm simply aware of sweating. I run a dehumidifier in a different part of the basement so the temperature may go up as much as 10-15 degrees F, but with judicious basement-door-opening I can keep the basement at about the 70 deg F mark.

Air temperature, air humidity, that's sort of based on your trainer room environment, your house. You need to take into account what you have, what you don't have, and figure out how to fill in the gaps.

Air Velocity

For me, for air velocity, I'm all set. The 20" Hamilton, model SFC1-500B, is rated at 3900 CFM on low, so at its lowest setting it moves about 150% the volume of the ubiquitous Lasko box fan on high. The Hamilton pushes 4700 CFM at medium and a hurricane-like 6100 CFM on high.

To give you an idea of how powerful the fan is, during a particularly bad storm I had water come into the basement (this was in our old house, leak was due to a crack in an add-on foundation area which we eventually found and fixed). Initially it looked like some water had just seeped into the basement, simply wetting the floor. It looked like I'd spilled a bucket of water down there. I set up the fan on high to "dry" the floor, pointing the fan at the wet floor to maximize air movement and therefore evaporation in that area. I also ran a dehumidifier on a counter top down there to dry the air. This set up my trifecta of air velocity, air volume, and air humidity. I hoped to check in a couple hours later to a nice and dry basement.

Unfortunately when I came back to check up on my "drying project" I found that the water level had risen unexpectedly. We had a few inches of water in the basement, with the shallow bit about 1" just near the fan - apparently our basement floor wasn't very level. I was worried that the fan would get shorted out, sitting in a puddle of water. But to my great surprise I found, in front of the fan, a miniature wave an inch or so high about 3 feet away from the fan. The fan was blowing so hard the water couldn't approach any closer. The floor in front was bone dry and it's where I staged the wet/dry vac to start cleaning things up.

So I have a very powerful fan for my trainer.

As a side note I've had the fan for maybe 12 or 14 years now, if not longer. I use it regularly. In some situations I'll move the fan to move air around in other parts of the house, like the wet basement (when we lived there) or, when we get hit with debilitating heat waves, I'll set it up to blow air around in the main part of the house. It's a solid, durable, reliable fan.

Air Humidity

Drier air will help comfort on the trainer. You cool off by having sweat evaporate off your body, but if the air is too humid the sweat simply cannot evaporate quickly enough or at all. When I was a kid we didn't have air conditioning so if I got sick and it was hot and sticky out it'd be hard to cool me down. If I was running a high fever my parents would carefully dole out aspirin to reduce my fever. I knew if they were really worried, or if it was really sticky out, when they patted me down with a towel dipped in a water and rubbing alcohol solution. The slight bit of rubbing alcohol was there to evaporate quickly - it evaporates quicker than water. My dad, the chemist, knew that the rubbing alcohol mixed with water would cool me better than just plain cold water. Just to be clear you should NOT be dousing yourself with rubbing alcohol on the trainer. There are problems with rubbing alcohol that far outweigh the benefits of its cooling properties when on a trainer.

Nowadays, in our house, we have air conditioning in the main part of the house but not in the basement, so the ambient (trainer) humidity is typically 70% or higher in the summer. On the first floor it ranges from about 50% to maybe 60% if the AC is falling behind. Temperatures in the basement range up to about 80 to almost 90 deg F; upstairs it seems that we aim at keeping it at 76-78 deg F, and at 80-81 deg F we want the AC on.

During recent trainer rides, with trainer room ambient temps into the mid 70s deg F and humidity about the same, I've had to use medium speed on the powerful fan, and I've started rides with it on low. Normally I use just low speed and I don't turn the fan on until about 10-30 minutes into a ride.

When it's super humid in the basement (I don't have a % number to reference but I'm guessing at 85% or higher) the problem is that so little sweat evaporates that I have to move a lot of air past me. Even on high I find that the sweat drips off me before it can evaporate effectively. These are the worst rides, I have to focus on making sure I have ice cold water in my Podium Ice bottles. The thing is that if you can't cool off from sweating then you need something else. Ice cold water helps a bit, at least a bit more than luke warm water. It also helps to douse a towel in ice cold water and then rub it on my neck, sort of the rubbing alcohol hack without the rubbing alcohol.

The Open Secret To Training Indoors

So that's my secret to training indoors so much, the high velocity fan. It's not that much money, about $45-60. I know the box fans are much less, but for you, someone interested in riding a trainer or rollers, it's a small price to pay for the difference in comfort going those trainer sessions. Even frugal me bought one of them a long time ago, I simply couldn't do trainer rides with a regular box fan.

How To - Be A Good Racer



Although it's been a bit nutty and I haven't really been able to post much, the reason for the frantic stuff happening before the Aetna Nutmeg Spring Series has to do securing a venue, making sure it's usable, and trying to make things happen so that we can all race. I may share some of the trials and tribulations in a later post but for now I want to focus on one thing:

How to be a good racer.

I'm not talking about FTP and wattage and intervals and tactics and drafting.

I'm talking about your behavior as a racer.

As a racer, what can you do to help the race promoter? Not marshaling and stuff, but just in being a good racer.

This is a key aspect in grassroots racing. The biggest challenge for a promoter is to secure a venue. This means getting permission to use a course (aka "permission to break traffic laws like 'not racing on public roads'") and the related costs to that permission (permits, police, department of public works stuff, etc).

After that it's pretty straightforward to hold a race, if one can say that.

There are a few reasons races die off. One is the venue gets too busy such that the it's impossible to hold a race safely. This happened to the Bethel Spring Series with one business opening up that put literally hundreds of cars driving through the venue over the course of a day.

Another is the promoter decides to pull the plug, either for money reasons (typically associated with the costs of holding a race, aka the costs related to getting permission to hold the race). I know there were a few "classic" races I used to attend where the promoter was sinking $8k a year or more (in the 1980s!). After a few ten thousand dollars of money tossed into the black hole the promoters in question gave up.

There are related things, of course. Poorly attended or poorly managed events may disappear quickly. Off-time events may not survive - crits in January in Connecticut, for example, or roller races in July.

Typically a grassroots race promoter promotes a race for reasons other than money. It's a sense of duty, a sense of "I have to do it because no one else is doing it", or something similar to that.

Therefore the worst reason to lose a race is because the racers misbehaved. To me that's just incomprehensible, for racers to behave so poorly that the event gets banned.

This has happened in the area, with a road race in Massachusetts. The race got canceled not because of venue permissions, venue traffic, costs, promoter burn out, scheduling, any of that regular "promoter headache" stuff.

The race got canceled because so many racers were peeing on people's lawns, bushes, buildings, whatever.

That's it.

None of us want a race go go away, and for one to go away because of racer behavior is just a kick in the face to the promoter and the host venue/town/area.

I'm going to make a quick list of things a racer can do to help keep a race alive, barring the other non-racer factors.

Good racers do the following things:

1. Smile and say hi to everyone, locals and racers alike. Happy racers are friendly racers are good racers are a benefit of the race.

2. DON'T pee in public. Just don't. In my races someone that pees in public forfeits their entry, prize, points, everything. Use the portapotties. Promoters pay for them, you might as well use them. If there aren't enough then mention it to the promoter. Trust me, the promoter would much rather spring for another portapottie than risk losing the race.

3. Change discretely. Imagine an (stranger) 8 year old boy or girl standing in the vicinity when
you're changing. Is what you're doing appropriate to do in front of them? If not then make it so. Cover up, close a door, whatever it takes.

4. Buy your food/fuel in town and post it on Facebook or Twitter wherever. The host town is hoping that by allowing the race to happen that they get some people to spend money in town, Facebook stuff, all that. A tired but happy racer chowing down is a great image too, for your sponsors and friends.

5. DON'T swear, at least too loudly. It's against the rules and for a reason - dropping F-bombs and such doesn't go over well with parents trying to do right by their kids.

I figure five things is a nice, sweet list. Short and simple.

If we all work together we can grow the sport. Yeah, promoters have to do whatever to hold races, and I understand that many/most of us racers have no interest in promoting a race. That's fine - it's like asking a sprinter to climb or a climber to sprint, I think promoting is something people do or don't do.

However, all of us racers enjoy racing, and we can all help whoever promoter at their race. Let races stand or fall on its merits. It's our duty as racers to honor the promoters' efforts to bring us races.

Helmet Cam - June 24th CCAP Tuesday Night Race, Bs, Heavy D Wins


So as promised here's one of the clips I finished in the last month or so. I uploaded this last night without issues so phew, my post yesterday was a lie.

This is the first in a series of three clips. They sort of fit together although it's not necessarily totally interlocked like, say, the Lord of The Rings trilogy.

But it's sort of close, you know. In terms of production quality, length, special effects, and storyline.

Or not.

Anywho… For the first of the trilogy it's a B race at one of the CCAP Tuesday Night Races. I posted a "pictures + words" race report here.

The attack that won the race.

For the action in motion, check out the video below. Remember you can click on the YouTube logo to watch the clip in YouTube. Usually it's the better way to do it because you can resize it, unlike the tiny thing embedded in the blog.

Enjoy!

Racing - CCAP Tuesday Night Race, May 27, 2014

So we did the first race after the slew of posts on how to race.  The chronology goes something like this:

1. We raced on May 20th and my teammates told me that none of them really every figured out what they should do during a race. One told me that his mantra was simply to "get to the front". The result? The team used a lot of energy during the race but collectively had nothing left at the finish. I know they're really strong because I can't do a lot of what they did during the race. Unfortunately they exhausted themselves by race end and couldn't follow moves on the last lap.

2. I wrote a post asking if racers wanted feedback. At that point I already had a few asking for advice, but I felt it best to put the advice out there in public so that all newer racers could benefit from it, not just Expo ones. The post had four main points. I chose those points because those are the things that the Expo guys mentioned, both directly to me as well as indirectly (I was eavesdropping on some post race discussions).

3. Point One - How not to get lapped. More accurately, how not to get shelled.

4. Point Two - How to draft.

5. Point Three - How to corner.

6. Point Four - How to go fast. This last one combined a few thoughts so it's a long post.

How did it go? Well it went really well. I told someone after the race that the team transformed from one week to the next. No one chased a teammate down, they waited patiently when they needed to, and they weren't afraid of going to the front when that was necessary as well.

Utimately a group got off the front with one Expo rider, and the rest bided their time for the sprint. Up front the one Expo rider (Nick) survived with just one other rider, a non-Expo, and so it'd be a two up finish.

Unfortunately the race got rained out - it was sprinkling lightly one lap, no problem, and the next lap it was a downpour.

This is how it went down.

Prelude

With showers forecast for the entire day just a few days prior I thought that the Expo BBQ night would get rained out. However by race day the forecast changed to a slight chance of thunder showers but no substantial rain until later in the evening. It was hot for us, 80 degrees or so, and very humid. The front coming through was supposed to drop the temperatures about 30 degrees so it would be a doozy when it hit.

The Missus and I have honed a system to get to the race earlier since Junior's schedule is such that I can't do the later A race. Therefore I pack the car and I get as ready as possible. I pin the number (same number each week), I wear my cycling shorts, I put on my heart rate strap, I even pump up the tires on the race wheels before I put them in the car. I just have to put the wheels in, stick the helmet on my head, start Strava, and get my gloves on, and I'm ready to race.

This day I packed the Expedition. I wanted the extra room so I could change and I also thought it would be better if it rained on us - more room for dry air means less humidity in the car. A side benefit is that Junior can actually see out the side of the Expedition (he really can't in the Jetta or Golf, the seat's too low), so he peers intently out while he's in it. He loves watching things passing by the window, pointing out trailers, trucks, tractors, stars, whatever he sees.

We got going earlier than expected and hit the first highway only a few minutes after 5. We got to the course at 5:20 instead of 5:45-5:50 which was our expectation. I got my bike ready, paid my registration, and met up with some of the Expo guys.

The skies looked threatening but the clouds weren't moving very fast. The sun beam part of the sky was creeping towards us and the dark clouds seemed to be moving away from us. I hoped that the rain would hold off and we'd be able to race. Plus Expo was running a BBQ that night so it'd be fun to hang out after the race instead of rushing off to feed Junior.

Race

We all lined up, a decent number of us. One team was noticeably absent (I think a bunch of them are 3s) but otherwise I think most of the regulars were there. Expo was missing both the 3s that would normally do the race, Joel and SOC. We got our instructions and just before they sent us off on a couple neutral laps Aidan (the race boss if you will) asked the Cat 3s to raise their hands.

One person raised their hand.

Me.

All Cat 3s raise their hand. Just one hand went up, mine.

I was pleasantly surprised when I learned the whole field consisted of Cat 4s and 5s. This meant the whole field was racing for the win, minus me, and it meant that no one could hide behind a "but that guy is a 3" excuse.

I liked that Aidan asked the question because it clarified exactly who was racing and who was not (the 3s approach the B race as training/mentoring, the 4s and 5s are trying to do well in it).

We started off and two laps later we were racing.

Major crosswind from left.
I'm sitting in the best wind sheltered spot, relative to #398.
Everyone to the left is hitting massive amounts of wind.

The wind hit the field from the left after the first turn, and as we all rounded the second turn it hit us head on. I'd say the wind was almost as powerful as it was last week. Based on the weather forecast that didn't surprise me - it was supposed to drop about 20 degrees in a few hours so that meant that some system was moving in. Nothing moves for free so it meant we'd see some wind for a while.

I drifted to the back of the group on purpose, to try and help the younger riders earlier. I realized last week that helping them after they'd gotten gapped didn't make sense. They were already blown so they didn't have the power to make the jumps necessary to stay on the wheels.

I decided that this week I'd sit back there, sit in the wind, and tell whoever wanted to listen to sit to my sheltered side. This race, on this night, it meant getting the others to sit at my 4 o'clock (behind and to my right) after Turn One and then sliding behind me after Turn Two.

I intentionally sat to the left, trying to give more sheltered lanes to the right, but I think some people misinterpreted that as an example to "stay left". As the races go on I think we'll see some improvement with Wind Management, but it seemed a lot better than even last week.

Someone had commented on the "danger" of overlapping wheels. It is technically more dangerous but when you're drafting in a crosswind there's no way to avoid it. In a headwind, or in "no wind" (i.e. the wind is from the speed of the riders, not nature), it's not ideal to overlap a few inches, but to sit to someone's side is not bad.

Of course I still saw racers leaving gaps and such. It's only normal - even in Cat 3 races you'll see racers do that. However overall I think people tended to be a bit closer exiting the turns, they followed lines better, and I felt like the field was more under control in the turns. Last week I saw many, many riders take different lines in the middle of the field. This week just one rider stood out.

Also it seemed that racers were quicker to close gaps and a bit more reluctant to take big but meaningless pulls. As I mentioned above I posted all my race advice for Expo on the blog so any of the competitors could read it. Good bike racing is fun, and racing with a bunch of racers that know what they're doing is even more fun. It's like playing a game with someone that is as skilled as you are, maybe chess or something like that. It's no fun playing with a brand new player just as it's no fun playing with a Grand Master. But get two evenly matched opponents and it's going to be a good game.

An example of Expo guys waiting.

In the above picture you can see two Expo riders waiting patiently near the front of the field. At least one Expo is off the front, although I'm not sure which attack this was so I don't know if there are one or two. Last week I might have seen two or three Expo guys actually pulling. This week they were all waiting.

I realized that my basic race craft stuff didn't incorporate any advice once things went well. One Expo, Nick, went off the front in a group of four and ended up staying away for the rest of the race. I realized that we didn't have any way of knowing if he felt good or not, and for Nick, on this day, it was a legitimate concern. He'd done three massive days leading up to the race (big miles and volunteer work Saturday and Sunday and then a big ride Monday) so he admitted feeling a bit fatigued before the start. Although he ended up feeling great in the race we hadn't figured out a way to communicate that. I worried that we'd see him drop back to the field after Expo had shut it down. This we'll have to work on for next week.

A gap that I didn't close.

At a different point a group of four rolled hard into the crosswind section (note to self: also need to give advice on when/where to attack). I rolled hard to keep the pace up but literally could not keep the gap closed. I eased and let the next rider through, and it was Vickie who pulled through hard and closed the gap.

As the laps wound down and Nick seemed to be gone I started thinking about the field sprint. I had no control over what happened up the road but as long as Nick wasn't suddenly in front of us it was okay, and even if he did blow, it was still okay. There was plenty of race craft we could work on in the field.

Rain started sprinkling lightly, a refreshing mist if you will, but I was a bit surprised. I started thinking about really pushing hard because if the race got called we'd want to be in position to sprint or something. We got into the last 5 laps so the race was almost over anyway.

At this point one Expo had rolled off the front. Two more were soft pedaling, trying to encourage someone to pull through.

Expo waiting.

Again, although minor in terms of "race moves", this was a great example of the discipline and control (and knowledge) that the Expo guys had learned over the course of one week. Even though the gap was just 15-20 meters it was still a gap and they practiced their race craft.

Once the gap closed I rolled forward.

A rider in white obliged and quickly closed the gap. At that point I went to the front, completing an Expo wall of sorts. We weren't going that fast, we weren't strung out, but the rain was just a touch heavier and I thought that maybe we should just drill it from here in case the race got canceled.

I figured the race would be called soon so I went to the front.
Note that the pavement is still basically dry and that the tires are dry.

We rolled by the start/finish area and I think it was 3 to go. We had Expo jerseys all over the front and as the token Cat 3 I felt that I should go to the front. The boys lined up behind me and let me dictate the pace. With three laps to go I knew I couldn't go really hard so I toned down that leadout speed and wondered what I could do to get the team to the finish in some kind of organized fashion.

The rain started pelting us pretty hard by Turn Two, and by Turn Three I went way wide to try and get everyone else to take a nice, wide line. I didn't want anyone crashing by going into the turn and trying to turn really sharply.

Approaching the line the race got called.
I sat up and looked down - note the raindrop on lens, wet gloves, wet tires.

My gloves were soaked by the time we got to the start/finish and they called the race. It's the smart thing to do, the safe thing. Yes, it would help to race a bit in the rain, but it takes just one slip for someone to crash, and it takes just one crash to get screwed up. I agree with the "call it if it rains". The promoters waited until the rain was heavy to call it - during the laps of the sprinkling rain it was all okay.

I turned around and went back to the start/finish area.
It was quite wet already.

The rain really picked up in the minute and change from 3 to go until I returned to the start/finish (I didn't take a lap, I just turned around at the end of the straight). Water poured off the tent sides and everyone was soaked, and the poor grill wasn't doing much to help. It felt pretty cold too, the wet combining with the wind and the dramatically lower temperatures.

The Missus had taken refuge with Junior under the tent, but he was cold and wet so she took him to the Expedition.

In the meantime I had some post race talk with some of the guys. The race went really well, a huge improvement, and you could see it in everyone's faces. They were happy with their races. They worked smarter, not just flailing away at the front. They'd started thinking like bike racers rather than bike riders.

Now we just have to continue the trend.

Tactics - Struggling With Peak Speeds

Peak speeds. One racer, after my leadout on Tuesday, said something about how fast Cat 3s can go. Really, though, anyone can do it. I'm no pro and in fact a strong Cat 2 could do what I did for many laps at a time. So what's the secret?

There are a few things you want to think about, to execute. I alluded to the possibility of a fifth post but I incorporated two things into this post, position/aero and peak speed workouts.

Position

First is your position on your bike. If you look at a picture of a Cat 5 race you'll see a lot of racers up high, hands on the hoods, torsos upright, racers that look like parachutes.

Then look at a pro race, or even a reasonable Cat 3 race. You'll see racers much lower, much more aerodynamic.

2012 Keith Berger Crit, Cat 3 race, from my post here.

The above picture is a nice example of some random corner in a random crit. The Expo rider to my right is a former New England Crit Champion (I was in that race and he and his leadout man just rode away from the front of the field, super impressive). He's been racing for eons. The rider in front of him is also a long time racer, I think he won the Cat 1-2 Killington Stage Race one year (and he's won all sorts of minor races). Both are on the drops, in total control, low on the bike, aero, efficient, and comfortable.

(I thought of putting a Cat 5 picture up but I think that a racer would take it personally if it was them, and every picture of a Cat 5 race out there are pictures of racers who are people. Therefore I avoided putting up a Cat 5 example picture.)

Low Position

That lower position isn't only more aerodynamic, it's more powerful. Think about how you pedal when you're climbing a hard hill. You lean forward, your nose to the stem. You're doing this instinctively because by leaning forward you can recruit more of your major muscle groups.

The same "lower position" obviously happens on flatter roads. By leaning forward more you recruit those same muscles, increasing power, but now there's the added benefit of aerodynamics on the typically-higher flat road speeds.

Last Tuesday I did a big effort on the last lap. I averaged about 450 watts for about a minute. The power level is in the realm of possibility of many of the riders in the race. You may be able to do it for 20 or 30 seconds but if you can do that then the power is there. More importantly that means the speed is there also.

By getting aero you gain more power and you reduce the power required to go fast.

One major aero rule - an angled surface, like an angled forearm or an angled bike tube, is LESS aero than a similar shaped vertical surface, like a vertical forearm or a vertical bike tube. This is why TT bikes have vertical seat posts - it's more aero than having a 75 degree seat post (or whatever non-90 degree angle).

Likewise it's more aero to have your upper arms vertical and your forearms parallel than to have your whole arm at an angle. Finally, relating to your bike on a Tuesday Night Race, a bottle in your seat tube cage is more aero (vertical) than the same bottle in your downtube bottle cage (not vertical).

Now I'm not saying you should be sitting upright so your torso presents a vertical surface, but if you're down low, you're struggling, and you have a choice of hand positions or bottle positions then you can make a more educated choice.

With that in mind let's move on.

Position Basics

Some position basics:
1. The most aero position is where you have your forearms parallel to the ground, which usually means the hoods. However your drops give you more control. If you're in the field then you want to be in the drops to retain more control. If you're at the front, if you're willing to gamble your collarbone that nothing will happen for a bit, then the hoods are fine.

Note: since it's a gamble to be on the hoods I prefer to be on the tops. Much of my riding is either on the tops or the drops, even in races, except when climbing. The tops offer no illusion of braking ability so it's a more honest position. It's a real gamble to ride on the tops in the field, but that's what you're doing, in a sense, when you're on the hoods in the field. Either way it's a gamble. I tend to gamble on the tops more than most people. I can ride on the hoods, I've ridden a lot on the hoods over the years, but the drops are my safe choice.

Note: in a related safety related thing I always wear long fingered gloves. It took one fall for me to skin my finger tips before I wore them all the time. Any glove helps absorb the scrubbing energy of pavement, but those with finger tips will save your finger tips.

2. Elbows in. There's no reason to have your elbows splayed out like chicken wings. You'll see some sprinters do it in the sprint but even they tend to keep their elbows out of the wind. One of the most amateur things you'll see in the lower category races are elbows out.

3. Knees in. Unless you have a physical problem (typically a hip problem), there's no reason to have your knees splayed out like chicken… wings. Their knees don't splay out so anyway...

4. No hip rocking. It's easier getting low when your saddle is a bunch higher than your bars. However your saddle-pedal relationship is sacred. You need to make changes relating to aero/position up front. Raising your saddle and making your hips rock is not the way to get more aero. When you fit a bike you start at the cranks/BB, go up to the saddle, then forward to the bars. If you need to change your torso angle etc without major changes then you need to do it using the front end of the bike.

There's a great piece on position, equipment, and aero drag somewhere, and for the life of me I can't find it. Basically someone did a test on a rider (I think a pro rider, and I think it was on a track). They had the rider use different positions and different equipment, from riding a road bike on the tops with a road helmet to the other extreme of riding a TT bike on TT bars with every aero bit of clothing available. Each set up had a power number next to it, telling you what sort of power you needed to put down to go a given speed (40 kph? 45 kph?). The numbers fell dramatically, from something like 400w to somewhere in the 290w range. That's huge, and it drops the power numbers from pro-level to Cat 3 level (and I daresay a lot of Cat 4s and 5s as well).

*edit - I sort of found it thanks to Mike R in Texas - it's in the German magazine Tour and it's from 2006 or 2007. The pertinent stuff is below and I can't find the original page/link for credit:
They put Uwe Peschel on a normal bike:

Needed Watts for Speed = 45 km/h :
Stevens San Remo bike with normal handlebar 465 Watts needed to go 45 km/h
Same bike Hands down the drops: 406 watts needed
Same bike Easton Aeroforce bar: 369 Watts
Same bike Triathlon position (5.5 cm lower bar, saddle forwards): 360 Watts
Same bike Triathlon position (5.5 cm lower bar, saddle forwards) and
carbon Tri spoke wheels front and rear: 345 Watt

Cervelo + Tri spoke front 328 Watts
Cervelo + Tri spoke front + disk rear wheel : 320
Cervelo + Tri spoke front + disk rear wheel +Giro helmet: 317
Cervelo + Tri spoke front + disk rear wheel +Giro helmet + speed suit: 307
Cervelo + Tri spoke front + disk rear wheel +Giro helmet + speed suit +
saddle 3 cm further back: 293 Watts
What I found interesting is that if you skip the major illegal-for-mass-start stuff (TT bars, aero helmet) you end up with a substantial amount of potential aero savings simply by changing position, using aero wheels, and using a few select pieces of cycle wear. This means that you can realize significant savings on your road bike when you compare a "not very low" position to a more aero position. In fact, by going to the drops the power requirement drops almost 60 watts, or about 13%! It's the largest savings of all the possible ones, and obviously it's cheap because it's free.

By the time you get to the bottom of the list he's down below 300 watts to hold 28 mph. That's closer to a mortal wattage.

In a related thing there was some article (that I really can't find) about Colby Pearce. He's a compact rider, a former domestic pro in the US. His claim to fame was his extraordinary time trial efforts. He wasn't that powerful for a pro - he could put down 311 watts for an hour for real - but he held the US hour record at 50.191 kph or 31.3 mph (that's when he did the 311 watts for an hour).

You'd think that going 31+ mph would take massive wattage but he did it at a touch over 300 watts. That's a very sane number, something that some Cat 3s could probably hold. The trick was his aero-ness, if you will. Holding 311 watts is one thing. Holding 31.3 mph is another. To put it in perspective he spun a 55x14 at about 100 rpm for that hour.

Also if you read some of the articles carefully about this or that aero bike, you'll see that the front-facing products (bars, head tube, front wheel, front brake) make the most aero difference. In fact I saw an interesting tidbit when Bontrager introduced their aero drop bar - the bike they showcased (a Trek 7-Series Madone) was supposed to save you something like 120 seconds over a 40 km time trial but the bars alone were responsible for 23 of those seconds (drag reduction 14g). The integrated brakes saved a bit more, 16g of drag, and the frame 60g. Although I don't fit a Madone, although I don't have a bike that can take an integrated brake fork like that, I can install a Race Lite Aero bar. I haven't, but it's a thought.

A final thought on aero stuff - if you want to use just one aero wheel, a front one gets you more aero benefits. However most aero wheels compromise your bike's handling a bit, so you have to think about that. I used to race with a front Tri-Spoke (aka HED3), a front wheel that's acknowledged implicitly to be the fastest front wheel you can get, at least based on all the Tour riders that use them in time trials even if they're not sponsored by either Specialized (the original wheel rights owner) or HED (the current wheel rights holder). My rear wheel was a plain spoked non-aero wheel for a year or two, the only 10 speed wheel I owned at the time.

Pinning Your Number

The racers that know me joke about how many pins I use on my numbers but there's a reason. I read somewhere (again, I don't have a link) about how much drag a flapping number generates. It's huge.

More importantly it's absolutely and totally preventable.

You know how I keep harping about using the drops? It's so that you can reduce the chances of losing control of your bike, at least compared to being on the hoods or the tops. If you know that in, say, every 1000 times you have to brake hard on the hoods you'll crash five times and but you'll crash only once on the drops, why wouldn't you just use the drops all the time?

Likewise if you know that your flapping number is worth 20 watts or whatever, then why don't you take care in pinning your number? It's free power and it's available every single time you pin your number on.

My number from last Tuesday.

I pin the number on the jersey while it's flat on the ground (or the grass in this case). Start at one corner (I like to use the spot where the pocket and side panel intersect, in this case the lower left part of the number). Starting at that point I know my number will be visible to the sides as well as from above.

I then work my way along the edge (lower edge for me). I start adding pins in the middle, to keep the number from ballooning out. I put those in the black part of the number so they don't screw up any kind of finish line camera.

Finally I finish with a row of pins at the top.

You'll notice that one pin ripped, probably while I was getting the jersey on.

As a promoter I bring my own pins, sometimes a box of them (1440 pins when the box is new). Since I'm using my own pins I don't have to worry about taking a lot of pins from the promoter, plus I reuse the pins. The trick is to keep them dry so if my jersey is wet I immediately unpin the thing. Rusty pins ruin your jersey so toss them in the metal recycling bin before you resort to using them for some reason.

Other Clothing

Although not a factor in most summer races, if you're wearing some cold weather gear - a vest, a jacket, stuff like that - make sure it's not flapping around. You give away power hand over fist when you do stuff like that.

At the 2014 Bethel Spring Series I wore a jacket in the first race. Not a big deal I thought, it's cold and I want to be warm. I noticed a lot of other racers used jerseys and vests. Then I saw a picture of myself with the jacket on. It had flattened out in front, turning into a huge wall of fabric.

I decided that I had to avoid wearing the jacket. It fit a bit loose and I needed something a bit more snug. I decided to wear a rain shell under a long sleeve jersey. That handled the wind (brutal when it's cold) and the long sleeve jersey snugged everything up. I raced warm and a bit more aero from then on. I happened to do a bit better but I think there were so many other factors that I can't give credit to my slightly more aero clothing.

Note: Motion attracts attention like nothing else, at least for humans. Humans see motion, color, then shape. Therefore when I train out on the road I try to use my blinky tail lights (mine have a super bright LED in the middle), I try to ride properly, and, if the weather is under, say, 70 degrees F, I wear a vest. I don't zip it up until I actually need it, which is more like the 50 degree F range, but I wear it if I can bear it. It flaps nicely in the breeze and helps attract motorists' attention. I got this tip via a motorcycle and bike riding EMT/fireman who once had an absent minded driver (he was thinking of his tennis game, this in the age before cell phones and such) ram full speed into a fire truck parked next to a burning house, firemen all around, and hoses and such leading to the burning house. I figure the flapping vest helps me train a bit harder even in my "always low always aero always riding in the same position as I race" training rides.

Um, Power?

Okay, so that's all great you say but you were going to tell me about how to go really fast, how to deal with peak speeds. What about power and all that? I mean, don't I have to pedal the bike in some special hard way to go fast, to hit those peak speeds?

No.

Okay, yes, you do, but it's a pretty straightforward process, at least it seems to be based on the feedback I've gotten on my technique detailed below. Basically you can do it now, it's just that you haven't practiced, you haven't done it fresh, so you don't know you can do it. Remember the power number I rattled off somewhere before? 450 watts. Everyone can go 450 watts, it's just a matter of how long you can go at 450 watts. For me it's about a minute. For Taylor Phinney he can do more (488 watts) for a touch over 12 minutes. Whatever it is for you, that's what I did to go "really fast" that last lap of the Tuesday race last week. You can hit that power and more and often it requires no actual training, just some practice when you're fresh.

It sounds a bit odd but it actually takes practice to sprint really fast. If you don't believe me then try sprinting when you're descending at 45 or 50 mph. It's really hard to apply power to the pedals at that speed without losing control of the bike. Likewise if you're used to topping out at 35 mph then responding to a 40 mph tailwind attack will take you into foreign territory. You need to familiarize yourself with those speeds so that they are at least familiar to you if not second nature.

The basic idea goes as follows:
1. Determine your Maximum Optimal Sprint Speed. I'll explain in a bit but basically this is the fastest you can go on a flat road in optimal conditions.
2. Compare your MOSS to various race pace numbers. I'll rattle some off to help you out. Average speed, 25 mph. Attack speeds, 28-32 mph. Normal fast sprint speeds 36-40 mph. Very fast sprint speeds 40-44 mph. I'm not going to go into the hyper fast sprints that you see on training rides, which can exceed that 44 mph mark.
3. See where your MOSS lines up. Ideally your MOSS will be in the normal sprint speed range, 36-40 mph. If it's below 32 mph then you need to work on it.

The problem is if your MOSS is low, like 30 mph. This puts your optimal max speed within a normal attack speed, a speed that even I can keep up for a lap at the Rent. That means that if someone attacks hard you'll struggle to stay on the wheels.

Your goal is to increase your MOSS as much as possible.

For more on MOSS go here. I explain how to find your MOSS and how to train it.

For inspiration here's a video that I put together from a bunch of training rides while out in SoCal in Jan/Feb of 2011. It includes two MOSS efforts, both about 49 mph:


(Tip: for YouTube videos embedded in the post you can click on the YouTube logo to view it on YouTube. It's bigger and you can see more. I've reduced the embedded size to fit smaller browsers so it's not great to watch the clip in embedded form.)

More Power Stuff?

No, no more training stuff. For most riders they already have the ability to deal with peak speeds. They sabotage themselves without realizing it and end up getting shelled when they could have stayed in the field.

Remember the prior posts, some of the points made there.

First, don't work unless you need to work. If you do a massive 25 mph pull for a few laps, great, but when you pull off and someone attacks at 32 mph, will you be able to follow? If the answer is no then you shouldn't do that 25 mph pull.

Increase the attack speed to 35 mph. Will you be able to follow?

Next, if you can't follow at 32 mph attack, what do you do? Do you pummel yourself at 28 mph, losing ground at 4 mph, hoping the attacker blows up? No, you don't, unless you're one of the last few to react. If you're already spent then you need to rely on others to close the gap for you. It's not always about you.

Of course if it's a teammate then you absolutely do not respond, unless the teammate is your leadout man. Normally if it's a teammate attacking then you ease if you're at the front. You ONLY follow another non-teammate's wheel. If another teammate follows the first one to jump then you wait again. You want to have one teammate go with each counter, with any well placed teammates at the front acting as deadweight at the front of the field.

On the other hand if you look around and see that everyone else is looking around then maybe you'll need to work. Or maybe the attacker will blow up. Whatever happens it's good - you're thinking about it instead of responding like a robot.

Example of Fit + Tactics as Relating To The Rent

So does this all work? Well, I can't make it work every time but I do have an sample size = 1 experiment from the past.

A friend and now-teammate of mine (I refer to him as SOC in the blog, but most of you who race in the area know who he is) had hit a plateau at the B races at the Rent a few years ago. An obviously strong rider, he had trouble doing well at the B race. He got second a bunch of times but couldn't quite win. Until he asked for help I didn't offer it (because that's the way I was taught to do things), but when he asked I think he got a lot more than he realized. I casually mentioned that I might want to change his position a bit. I had some tactical advice as well, but that would follow the fit part of things - without the fit he'd be wasting a lot of energy.

Fit Changes

So we made a major, major change in his fit. We raised his saddle 17 mm, moved it forward 10 mm. We dropped his stem 25 mm (a full inch!) and installed a 12 cm -10? degree stem to replace his 10 cm -6? degree stem. I'm not sure of the angles, I'm pretty sure I was just looking for the longest, lowest stem we had in the pile of "borrowed take-off stems" from the local shop.

Those are some massive, massive changes, and in fact I played it a bit conservative because they were already getting so big. I think I vocalized the fact that I wanted to try a 13 cm or even a 14 cm stem (-17 degree), and if I didn't I was thinking it quietly.

We arrived at the fit just like any other fit - start with the saddle position, finish with the bar position.

I didn't want to change his saddle height much because it would screw up his legs, and by July he had a bunch of miles on his legs. I don't think we changed the height, we just moved the saddle around the arc of the circle defined by his saddle-to-BB distance. This keeps the saddle height the same (as far as the legs are concerned) but rotates the pelvis forward. I think we flattened his saddle out a bit, it might have pointed down more at the beginning. With the saddle position now set we could work on the front end.

(Keep in mind that since we didn't really change the saddle position it wouldn't really affect his leg muscles. There'd be soreness from the other changes but the legs would mostly be the same, except for the heavier emphasis on the glutes and related muscles. This means that any prior training would be applicable.)

For me the goal was to extend the reach so he'd have more weight on his arms while still allowing him to breathe and see normally. It wasn't just "slam the stem" - we actually thought about the changes. He felt comfortable, albeit a bit low, and once he started pedaling he had decent weight distribution between the saddle, bars, and pedals.

The lower and more forward bar position would increase stability in the turns by weighting the front end more. It did slow the bike's turning at walking pace, like if you were turning around on a sidewalk, but once you get over about 12-15 mph the front end of the bike feels super stable. The heaviness of the slow steering so unnerved him that he almost turned around halfway down his 50 foot driveway, but with my encouragement he kept going.

The lower and more forward position also enabled him to recruit more muscles, especially his glutes. This in turn allowed him to exert more power to the pedals.

Finally the longer and more forward position gave him a much lower profile, improving his aerodynamics.

I'm sure that with more fine tuning we could make even more improvements but at that time it seemed like enough.

For the fit I only drew on my past experience, feedback from the rider (before, during and after the fit, the latter in case there were any major problems with the position), and the available parts we had with us. We didn't have any longer stems, no -17 degree stems (zero rise), etc, so we did what we could do given the ingredients we had in front of us.

Tactical Advice

The other thing I told him was that he shouldn't be attacking willy nilly all race long. It's a rehash of some of the stuff in the earlier posts of this set. Sure, he could do the odd move here and there, but if he wanted to win then he needed to learn how to win. I told him to sit and wait and build reserves for the finish. Follow wheels, make sure to keep gaps closed, and meter his efforts. His fitness would get him to the finish, his hopefully improved power bump him up a bit, his better aero let him be more efficient, and finally the better weight distribution on the bike would make it easier on him in the turns. However he had to execute in order to win.

During the course of the next few weeks he raved about his new position. He had more power, more speed, and he felt the bike was more stable in the corners.

So how did it work out?

Result Of The Fit and Advice

The first race out he won the B race.

He won the next B race.

He got 3rd at a very tough weekend race. (When we raced it together as Cat 3s in 2010 he got 2nd and I was almost dead last, and that was the year I upgraded to Cat 2).

He won the next B race. And he finished the A race, which for me is always a challenge, even in the aforementioned 2010 season.

In years after that there was one thing that stood out in particular - He had a sudden flat (tubular tire) in Turn One at the Rent. He'd just bridged to a break so he was probably going about 28-30 mph. Not only did he not go down but he rode for a bit, confirmed he had a flat tire, and then finally stopped on his own. Yes he was on the drops. I have it on helmet cam somewhere but it was so undramatic I haven't even bothered getting a still of the incident.

Also, in 2010, he won an A race outright, something I've never done.

He is still using the same position.

Conclusion

So that's my bit on approaching the Tuesday races at the Rent for a newer racer in the B races. You should struggle the almighty struggle to stay in the field. You have to think a bit about drafting efficiently. You need to think about cornering properly, safely and efficiently in the field. You need to do some exploration of your maximum optimum speed. You should give yourself an honest fit appraisal ("an honest, no BS assessment," to quote some movie whose title/story/theme/etc that I can't remember now.. this inability to remember things is really bugging me).

In 4-6 races you should see a dramatic improvement in your performance. You should be analyzing your races more closely. If you get shelled then you need to think about why you got shelled. It's not just "I blew up". It might be something like "I wasn't on a wheel going into the headwind for 5 laps and I had to sprint for 100 meters every time we exited that turn." With that kind of analysis you can think about how to improve.

Even if you don't get shelled, if you didn't win or didn't help a teammate win then there's room for improvement. Think about where you made mistakes. Did you leave gaps in certain turns? Did you stay left when the wind was from the left, even though you had room to move right? Did you do a hard pull without saving anything as a reserve and then watch the winning move go up the road after you pulled off?

Unfortunately if everyone applies themselves then the races will become that much faster, that much smoother, and perhaps a little bit harder, so when you chase improvements you'll be chasing a moving target.

Ultimately, though, all this results in you being a better, more capable racer. It requires no extra training, save a few efforts to determine your max speed. I haven't said a word about hours per week, about wattage or intervals or cadence or gearing or anything else relating to training. It's partially because I don't know about all that stuff, at least not well enough to talk about it to anyone. But it doesn't matter anyway because you already do all that. Now you can apply all that precious work to your racing more efficiently, more effectively.

The beauty of bike racing is that you can always strive to race better. Our fitness and preparation vary throughout the years, changing year by year, month by month, sometimes week by week. Work, family, school, personal stuff, it can all take a toll on your bike racing. However, once you're at the race and you've pinned a number on and you're lined up at the start then it's time to race bikes. You don't have to worry about anything else. You have what you have, based on your fitness level and experience. You can't change your training now. You also can't dictate what you do in the race - it's not like everyone is going to ease up so you can go 180 watts for the race. When you finally clip in as the race starts it's up to you to go and make the most of it, whatever that might mean to you.

Final inspirational video for you:

The above video includes someone leaving a gap, watching SOC attack and letting others work, following a counter (and then getting countered hard), ending up in the 3rd group, getting gapped off the back of that group, watching the 3rd group catch the 2nd group, team attack, catching the break, lots of attacks/chases, hanging onto wheels, and a field sprint.

In fact I'd claim that these pieces offer universal advice for all new mass start bike racers.)

Tactics - Cornering

The next bit on the four part series is cornering. The Rent is a great race for new racers because there are corners enough to challenge you but not getting into the "dangerous" range of corners. Yes, there have been crashes in corners, but generally speaking the corners at the Rent are manageable with the 40-60 rider field sizes we see on a Tuesday. It helps that the race gets strung out pretty regularly so the field is only a few riders wide at speed.

Cornering Can Be Scary

I think the scariest part of mass start racing was the cornering in the field. In fact even now, when I get to a race and I see a pack of racers diving into a turn, I wonder how they all make it without crashing. Of course once I'm whatever race I'm doing then it's okay, but watching it from the outside is still intimidating for me, 30-odd years after I started racing.

I addressed some cornering thoughts in previous posts on the blog. One highlight:
Late Apex and Looking Where You're Going

The big takeaway from that post is that you should strive to look where you're going. I've read (but not confirmed) that people tend to go where they look. For me that holds true so I try to look forward through turns. I do look around the front of my bike also, just to be safe, but generally I'm looking forward.

How Do You Corner In A Field?

The most important thing when cornering in a field is to follow the other racers. It sounds basic but you'd be surprised at how many racers try to follow some imaginary "optimal line" and end up going across other riders' paths.

Optimal cornering lines only exist if you're riding alone or, in rare cases, if you're leading out a very strung out field. For example, in this leadout, I knew that the field was waiting for me so I could choose any line I wanted, and I chose an early line. The pertinent part starts at about 7:45 or so, when I'm in the lead.


If you're not on your own or leading out the field then you need to adapt your line to those around you.

Recently I've been thinking about how I corner in a group, to try to explain it to others. I found that I basically do the following:

1. If on the inside I follow the rider in front of me.
2. If in the middle I follow a path parallel to the rider to the OUTSIDE of me.
3. If on the outside I follow the rider in front of me or do a parallel line to the rider to my inside.

By focusing on the riders around me I avoid looking at the curb and therefore cutting in too early or too much. This is a common error with new racers, where they turn in too much, then they correct and swerve out. By following the rider in front you avoid creating new lines and you keep the field in harmony.

Obviously I'm keeping an eye out on curbs and such - if following one of my basic rules above puts me into the curb then that's no good. A few times this year I've found myself skittering on the edge of control as the field collectively went really wide, putting most of the riders on the outside into the curb. The trust that the racers had in each other meant that many of the racers, including the really experienced ones, ended up following riders on lines that were just a few inches too wide.

Where Should I Hold The Bars?

For me this is a huge peeve. All too often I see riders diving into pretty dicey corners on the hoods. For example, in 2010, at the New London Crit, I was vying for position going into the last turn. The course was really interesting, it had a one lane (with curbs) downhill going into a super sharp corner (well it was way more than 90 degrees) into an uphill finish.

The guy in front of me went into the turn on his hoods. His front wheel washed out and he crashed. I was on the drops, I could avoid him, and although I had to brake really hard and shift down a couple gears, I got going again and ended up placing in the race.

The answer, assuming your bike fits properly, is that you should be on the drops. The drops give you the best braking, best steering, and best overall control of the bike. It usually gives you more power and speed but that's for a different post. Right now I'm concerned with finishing the race, and since the corners are the diciest place in a race, you need to stack the odds in your favor that you'll finish the race. If you stay upright then that's good, and being on the drops increases those odds.

A few years ago at the Rent a guy rolled his tire going into Turn One. A very, very, very good racer was next to me, on that rolled tire guy's wheel. He happened to be on the hoods. He ended up crashing and breaking his collarbone. I don't know if he'd have been able to save it if he'd been on the drops but from my video it's apparent that the racer had to give up trying to stay upright because he couldn't slow down nearly enough. He couldn't steer or brake enough to save himself.

I was on the drops. One of the bike's wheel hit my neck, but I was otherwise fine. I fixated on the curb and fortunately managed to avert my eyes (and my path) and didn't it that curb, but I never felt like I was out of control.

You should get into the habit of using the drops when you're in flatter terrain or on downhills. It's a great default position with virtually no drawbacks (on a properly fit bike). You should be able to turn, brake, and shift 100%, and if that's the case then there's little reason to use another position.

There's no hill at the Rent but a great default position on hills is on the hoods. That's a different topic though.

Front Wheel Weight

Not your front wheel's weight! I'm talking about how much weight you have on your front wheel. If you're on the drops you put a bit more weight on the front wheel. For virtually all paved corners this is a good thing. You can almost always recover from a rear wheel skitter or hop, but if your front wheel goes sideways the chances of staying upright are a lot lower.

Therefore it's important to weight the front wheel. It's easier to do that when you're on the drops. I also slide forward on the saddle. This lets me blast into turns with a lot of confidence that the bike will go where I want it to go.

Pushing Away From The Front Wheel

When a rider gets scared in a corner they push away from the front wheel. They tend to sit back, they literally push the bars forward, and they'll even stand up out of the saddle. An additional normal reaction is to do an early apex, i.e. enter the corner early. All of these instinctive reactions make the bike handle worse in corners, making the rider even more scared. It's a bad cycle and you need to avoid falling into it.

It's not just the amateurs either. An unfortunate example of a pro rider like this is Levi Leipheimer. When he raced for Gerolsteiner he made a huge move on a stage in the Tour. He gave away minutes on the descent as he screwed up the corners, doing many of the things I list above (in particular his early apexes, sitting back on the saddle, and unweighting the saddle).

I've fallen victim to this as well, when I first descended down Palomar Mountain near San Diego. It's 35 minutes of descending for me, it's quite steep, and there are a bunch of switchbacks. Some are blind, meaning you can't see the exit point of the hairpin.

However the scariest parts are the fast sweeping turns, especially the ones with just sky beyond the guardrail. The drop offs are pretty big (being scared of heights I avoided stopping and looking down on the way up) and obviously if I made a mistake, or I had a massive mechanical, it would be bad.

Descent on the way to Palomar.
Trucks regularly pass me going about 50 to maybe 65 mph.
I typically hit about 45-50 mph on this road.

Well I found myself pushing the front wheel away from me, pushing the bars away, trying to get away from the guardrail. This unweighted the front wheel such that I had to go really slow in some of the corners and I was still drifting to the outside. I was turning in early, in spite of myself, so it was even worse. I came to a stop once on the wrong side of the road and basically had a miserable time doing the descent. I even got a crick in my neck from being so tense, and I had to actually stop to let my forearms rest because I was braking so hard.

In later years doing Palomar I could descend on the drops comfortably. I had more confidence that I wouldn't go shooting off the cliffs (even if I had a massive mechanical - I thought of how I'd slide to catch the guardrail etc), I had confidence in my cornering ability, so I could weight the front wheel like normal. This let me blast into turns quick enough that I could catch a car halfway down the mountain.

Conclusion

Essentially when you're cornering in a field you want to follow the field. Think "school of fish". Follow the other riders' line, they follow the riders in front of them, and everything works out nicely. If you try to do your own thing then it gets a bit messy.

Remember that cornering well lets you stay in the draft better and gets you going on the next stretch of road closer to a sheltering wheel. This increases the chances of you finishing the race.
