There are also rides leaving out of Plano Cycling and Fitness and all of the Richardson Bike Mart's. (I am partial to Plano). Also, they both offer indoor cycling during the winter months. Again, being partial to Plano, if you are interested, check out www.bikinmike.com. He is who leads the spin classes there. They are actually in the building across from Plano, vs RBM is actually in the shop.
