I'm new to the saddle, and have been spending the afternoons riding through the country, practicing. Unfortunately, I can only make it about 2 hours before my body is on fire. Of course, it's practice, so I'm moving around a lot more than most people commuting would be, but groin and neck pain are rather significant. I know my body will adjust with practice, but I was wondering how long our senior members can go on a bike for fun before they need to ice down their delicates.
