Welcome back to the joy and challenge of cycling! Twenty years is a long time off for those of us fifty and older. Sounds like both of you are doing it right, taking it easy and one step at a time. Unfortunately, your wife found out it's easy to injure your knees or achilies tendons if you're not well prepared, or are pushing too hard. I took up long distant cycling while in my middle forties and stopped about two years ago because of a cancer problem. That problem has abated now and I'm having a bit of a challenge getting back into riding again. The extra twenty pounds doesn't help, and at sixty-three, the soreness seems a bit more then I remember, but I'm making headway. Hope both of you enjoy your forty-five mile Taylor House Cancer Centre ride in Flagstaff.
