I don't know if I will ever be as fit as I want to be. I ride 5-7 days a week and try to push myself a little harder all the time, but I'm satisfied knowing I'm in better shape than 90% of people my age...maybe even more. My biggest problem is finding time to do longer rides. I can usually only muster up an hour or so which means only about 16-25 mile rides mostly. If I could do 25+ miles more than 5 times a week it would help I'm sure. Stay with it, it's a slow process.
