This season will be my first year racing and I have a couple questions. I am 17 right now and will turn 18 in April do I still qualify as a Junior? or should I register as a collegiate rider? (I had a really hard time deciphering any thing from the USCF site)?Also if I am liscensed as a junior or collegiate can I still enter and ride races in an open category such as Cat 5? Also I'm not currently in a club but may join eventually will I have any problems doing that, what will it entail?
