Just to add another voice of agreement to the other ladies. Don't worry about the rain effecting his riding. I did my first Crit last year and halfway through the heavens opened up and it poured for the rest of the race, we're talking you could hardley see where you were going a few times. And no one in the pack had problems with it. The only problem I had was that I didn't know how to draft in the wet and kept drinking that nasty tire wash.
