My son is an amateur rider with some experience at trail riding. This is the first time we have been to a TCCRA race so I don't know if he'll want to do the big bike track. He rides an 85 and i'm wondering if he is allowed to ride it on the peewee track during practice. I understand that the big bike track classes start with 85s and the peewee track classes end with 65. Please answer, can he ride the peewee track during practice?
