As a solo rider, sometimes I worry about over-use injuries - or just plain wearing out like a football player does. There's no one around to tell me -don't ride. So I take a break between Christmas and most of January. So far, my body doesn't seem to complain - if it wines, I do let up on the intensity though and I'm careful about feet and knee issues - any wining and I swap out shoe pads or recheck my riding position (or gear).

Anyone encounter that?
