I didn't get back into riding until my wife bought me a bicycle for my 63rd birthday. For the first couple of weeks, I was lucky to get in 1-2 mile rides without my legs feeling like they were on fire and still be able to walk. I'm now 70 and average over 200 miles a week. My latest thing is doing as many 1,000 mile months as I can during a year. Like others have said, start off easy and don't try to put in too many miles unless you've worked up to it and you really feel comfortable doing them. Enjoy the miles you are riding and don't feel as if you have to compete with anyone but yourself.

I walked into a bike shop a few years ago that has a sign over the counter that reads, "The more you ride, the better you get. The better you get, the more you ride." It's been my cycling motto ever since.
