At age 66 I’ve been a roadie for almost two-thirds of my life. When I had my annual physical last year I told my doctor his job was to keep me riding for (at least) another 20 years. When I started riding in my 20s, each spring we rode centuries and the annual Davis Double Century to get in shape for touring. In my 30s I found that I excelled at long-distance riding and I became very competitive. As I got older, though, I started exercising more for fun and fitness and less to prove anything. Today, I exercise for recreation. If it's not fun, I don't do it.
