I agree with Eden that 1 mile sounds a bit on the long side for a crit. Last week, I did a race that was a 1.2 mile loop, and they used road race rules.

Are there hills on the circuit? That could also make a difference, especially in the difficulty level. And also agree with Eden's recommendations - especially the hay bales. I've seen lots of people need them, and had a teammate injured when a sign post didn't have them, and she ran into it.

Good luck with the race! Sounds fun.
