I've been registered on here for a few years but never really been active. I've had bikes on and off for years, but never really got serious. Well, I now need and want to get serious about riding. At this point, a 4 mile ride gets me winded so I know I need to build up endurance. I just picked up a Randonee with the aspirations of doing centuries and rides like the MS150. Other than the obvious of saddle time, any other recommendations?
