There's a junior group on the Computrainers (basically computerized bike trainers) doing a 2hr session every Tuesday. It feels odd to join a bunch of 12-15yr olds, but the schedule works perfectly with my day so why not! We can suffer together. :)
My ass hurts!
That age is perfect to keep you on your game. How does that work? You have a program hooked up to your own stationary bike?
