Where are the classes listed? I'd like to do one myself. I did one at TV Land before-- it was alotta fun.
I'd ride along at less than full pace, and gather up little tricks to save you time on the next lap around.
Also-- after the start, the riders will be all bunched up at some point. Watch the start of the race before you. Look for a spot to pass the 50 riders that'll surely get packed together. I did that, and ended up way out in front of my class. I'm a sh!tty rider though-- so they eventually caught me later on. Look at the sign up sheet and pay close attention to who the other riders in your class are b/c you'll be riding with other classes. I stayed tight with the riders in my group and looked for places to stuff them on the last lap. I didn't want to race other riders that weren't in my race, because I didn't want to lose touch with the guys I needed to beat. haha! Good luck-- and post up the classes. --L*64
