I'm with a lot of the others here... as long as you're still moving, who cares if you're riding all the time? Be gentle with yourself. If you're not feeling it, do something else!

I used to be pretty hard line about that sort of thing, but I'm a lot more relaxed about it all now. I used to road ride, period. 4-5 times a week, about 3000-4000 miles yearly. I had a serious accident on the road in 2005, and since then, I just haven't been nearly as interested in road riding. I might become so someday, but for now, I ride a mountain bike on trails more like 300-400 miles yearly. I don't even bother riding in the winter unless we have an unusually warm day. I also run, hike, sail, lift, walk, and most recently, do Pilates (just started a class at work). Oh, and I'm doing the One Hundred Push-Ups program lately too. So, I'm still very active and fit, and I don't seem to get injured any more because I switch up my activities. I love it all! Sure, right now I'm not able to do a century ride or a long bike tour like I could before my accident, but I couldn't run a mile then either!

It might sound blasphemous to post this on a cycling site, but there really is more to life than riding!
