I was on crutches for a month or so and limped for the first couple years but eventually adapted. The bike has helped a lot. I have to pace myself. I have to take care of my legs, I can't just hop on and pedal willy nilly like mad anymore. Lots of stretching, strengthening, massaging, and ibuprofen helps. Bike fit became pretty important once I started commuting every day. But most of these things I think are par for the course for pushing 40, and for cycling in general. I may be delusional, but I still think my best cycling days are yet to come. I haven't really tried jogging much yet. I bet it would hurt.
