Crit practice allows you to do structured intervals in a group setting, if that makes any sense. Since you're going around a loop, you can do your 1-2 min efforts either off the front, on the front, off the back, whatever, and know you're not going to get dropped since you can catch the group as it comes around. Although it's not that much of an issue these days, in the past I have been on group rides and sat in a little too much because I was worried I'd be spit out the back in the middle of NoVA with no idea how to get home. With crit practice, blowing up is the name of the game, if you get dropped, who cares!?
The other great thing about doing fast laps is that you get to work on a couple of important race situations - attacks, bridges, and positioning. Although it's not as aggressive as a real race it's not a bad simulation. The attacking practice is really important for guys like me that don't have that much experience racing. This year was the first year I have been something other than pack fodder, and so working on attacking finally became relevant. Attacking is a lot more than just riding hard off the front and most lower cats really f this up. Most of the reason why cat 4/5 races are such a big blob with no breaks is not because the riders going OTF are weaker, it's because riders in the pack that think they are "attacking" to bridge up are actually just dragging the field up.
I have to go off an a tangent here. It's really annoying when guys ramp up the pace with everyone in the pack right on their wheel. Don't they look behind them and see that the end result of their move is to just suck everyone along and force a reaction from the pack? There is 0 reason to do this, except in the following circumstances which apply to maybe 1% of the times someone nails the break back:
- Your team has a sprinter in the pack and you want to prevent any breaks from getting a gap because you're confident that your team has a better chance of winning in a field sprint than out of a break. However, even if you have the bomb-diggity cat 4 sprinter extraordinaire sitting in the field, what's the harm in trying to bridge to the break instead? You're going to blow up your lead out train or something?
- You love to be a sled dog to chase anything and everything that goes off the front. Sounds like a personal problem to me.
- You showed up to the race and your coach told you to pull everyone around all day because you missed all your threshold workouts last week.
- You're trying to get recruited as the lead out man for the best cat 4 squad in Northern Virginia.
- The cameraman taking pictures is on the back straight so you really need to position yourself well for that.
I really want to hear from people who think there are some other valid reasons for this move. I just call it negative racing, it prevents anything interesting from ever happening. I don't actually believe most guys are doing it on purpose, they just don't actually know what an attack is. Staying seated and rolling off the front at 1 mph faster than the guy behind you is not an attack. An attack requires gapping the field by 10-15 bike lengths is a few seconds. Otherwise someone will just sit on your wheel and take a free ride. If you look back after 10 seconds and the whole field is behind you, you're not attacking.
Anyways, crit practice is a great place to work on this. Timing of an attack at the end of the race is as important as raw power. I am not a strong rider when you compare my power data against other competitive riders in my category. However, I've managed to cat up this season with positioning and timing, essentially knowing when to use the sad amount of power I have. When I went all out at Hagerstown, it was an all or nothing commitment. If the pack caught me, I'd be going across the line dead fucking last. That's the type of commitment you need to have when going for the W. If I was a sprinter, I'd sit in until the last 200m but the best I can do in that situation is a top 5. In the 3s, my best pack finish will be out of the top 10 I'm sure. Crit practice helps define your limits and allows you to test out the attacks. The week of Hagerstown I did two all out attacks in practice with about 600m to go just to see if I could create the gap and hold it. It worked well enough, so I tried it in a race.
Maybe we can turn crit practice into a Greenbelt style training series, but honestly the current format might even be more conducive to training since it allows everyone to take some risks. With limited bragging rights, you're just worried about getting a good workout. At least I hope that's how people use it.
