I've done a couple. I'm kind of thinking of joining Porcupine Cycling. The usually have a big showing at those and they meet up close to where I live.
I started going to them this last year and ended up in a huge crash in my first race (first corner, 1st race lap), it kind of scared me away from them for a while. I did some more and learned that I hadn't been training nearly hard enough to race.
I like it when they have the course inside the little track oval, but when they loop around the outside there's some tight corners and i'm not aggressive enough on them.
This year I hope to do the Salt Aire TT, and the DMV crit
Present. The overly verbose (some would say enthusiastic) report is here. Short version: My first race, 3/8 mile laps on the oval (not the regular track), started badly, couldn't catch the lead group, got lapped halfway into the race, hung with the lead group the rest of the race, finished just behind the group but a lap down, had a great time.
