I'll be 52 in a few weeks. About 7 years ago I stopped running half-marathons when cancer treatment rendered me uncompetitive. For several years I tried to come back, but eventually realized it probably wasn't going to happen. I began mountain biking so I could continue to play outdoors. Now I compete against the trail rather than the stopwatch. It's my main passion, but this year I began commuting by bike to work and developed a love for the road. As of yesterday, I own a road bike as well, and intend to give it a good work out this summer. At any rate, I am in better physical condition than the women I work with who are half my age. They may be thinner, but I am stronger and healthier.
