hey… if you are the kid i think you are then you know where to find a bunch of riders each sunday. some of whom you have already talked to.
there are a couple of people there that can probably answer a bunch of your questions… or point you off in the right direction.
or you could come down to the start of a wed night ride where theres even more experience (you can have a nice ‘training ride’ back up to home afterwards.
the first step might be taking a deep breath and spacing your questions out a touch. we were/are all as excited as you at one time. but there is a lot of good information out there that just requires doing some considered googling.
just re-reading this thread reminded me how much good info was in it… take some time to digest it, and contact some of the people, or visit some of the places mentioned. youll get a lot more info (and in a coherent fashion without being flamed) if you ask face-to-face.
you wont become a champion track racer in one week… patience is the key both online and offline.
good luck… there seems to be a tonne of junior track racing programs/schedules out there, im sure you will find one that works for you.
