In my case I don't need the workout. I work out 7 days a week so this class would be replacing another workout.
I am new to biking ( unless you count bmx bikes as kid and putzing around on a mountain bike early 90s ).
I would die trying to keep up with 15+ mph guys that go two hours plus. I am just trying to think of ways to train and get better. Seems for the most part I should just ride my bike more. Take the long way home on my bike.
I hate the spin class bikes anyways because they don't freewheel. Hurts my knees when I stand up, spin/sprint and then try to slow down.
Thanks for everyones input.
