Need help with training

[Rockjock]

Hi all.. My 15 yo son is riding the Spur high school series. Now I know that everyone says, at his age he shouldn't concentrate on training a lot..mostly riding. However, with school ect he cant really ride enough and i certainly cant always ride with him which is a safety concern. He does have a bike setup on a trainer and ive committed to take him to krugersdorp for night riding every 2 nd week. Saturdays hell ride our local trail, xc style incorporating some hill training ect. We need someone to help with a trainer based program for Mondays, tues, every 2nd Wednesday and off bike exercise on Thursday. Any help would be greatly appreciated.
