Robertj298 I am 79 and just started back after a eight month no riding. The first two short rides the legs were on fire. The third ride legs a lot better but I was still puffing a lot.. Yesterday and today forgot about the legs as no pain there and I road 10 miles none stop with no slowing down just a good steady pace. I felt great when i finished. A little later I felt tired but the good work out type of tired. Wife said wow you were gone for quite a while. I have started a few older people riding and I had to stop them from over doing it at the start. Ride for the fun of it.
