aikigreg: I do a 20 mile training loop most nights and average 15 mi/hr. However, I feel great at the end of the ride and I know I could go faster. I am 206 lbs and ride a 28# steel bike. Also been training for about 2 months and have seen weight loss and feel great. Hoping to get to a century this season.
I really got a kick by reading the Burke and Pavelka book Long Distance Cycling and I recommend it to y'all.
