The main reason I'm considering this one at all is that it's the only local race in the next month or so, and I want to race! There aren't really any other opportunities to learn between now and the next 4/5 race other than just getting out and riding with people.

I think it is a pretty hilly race, 3 long laps.

Thanks for the thoughts everyone, I'm going to keep considering it. Haven't made a decision either way but there's been some good info in this thread and I appreciate it.
