Last Saturday I rode in my first crit. I'm 22 and relatively fit, so they threw me in with the B grade riders (Masters B + Elite C). No idea how that translates over to the US system, as I'm in Australia.
Supposedly the race was quite a fast one, ~41-43km/hr. It was noticable towards the end with less organisation and people less willing to do the work, the speed dropped right off and we started to bunch up. With 53 riders, some of the corners got a tad dicey decent during those slower moments.
Given that it was my first crit, I spent most of my time towards the middle-tail end, getting comfortable with the circuit and the people I was riding with.
Moving up through the field, finding a wheel I liked, then all of a sudden ending up on the front end. So I got to drive the pace for almost a lap - hard work
Unfortunately my Garmin ran out of juice around the half way point, before I ended up at the pointy end. But I'll link the segments below.http://app.strava.com/activities/32579367
For anyone thinking about racing, and being unsure - just jump in and do it. It's SO much fun and you learn a LOT. I'm looking forward to the next one.
