I don't have much to add on clothing choices. I am a former injured runner who recently took up cycling. Needless to say, I am still trying to figure out cycling clothing.

But I live in GA and I am so bummed that I can't go to the Twilight Crit. in Athens. I haven't been for years and now that I am cycling again I really want to go.
Well, I have a good conflict. I will be watching my boys at the Dogwood Regatta in Oak Ridge, TN. My DH and I will be on our Mt bikes following the races on the bike path.

Hope you get a lot of good tips. I'll be reading and learning along the way.
