I quit riding for the same reason 4 years ago. I couldn't keep up or pass kids on coasters. Two years ago, while waiting for my bacon double cheeseburger, fries and double chocolate shake from the drive in I walked into the LBS next door and walked out with my beloved Bianchi. I was forty pounds heavier, grumpier and older. It took me some time to give up on every being in the front of the pack or winning the Tour. Every time I get on my Bianchi or my commuter, it is not about the finish line it's about the journey. 7500 miles and 65 pounds down later, I grin every time I hit the pedals. I am slowly getting faster. Getting faster involves intervals, long slow training rides, rest days and diet. In two years I've gone from 9 mph to 15-16. It doesn't really matter. This truly has been the adventure of a lifetime!
