I'm with TSL. I want to be the best I can be, and get respect from the other riders. I'm the oldest regular rider in our club at 63, and though I've only been riding 2 yrs I'm a pretty solid b+ rider. I can hang with the A group for 20 mi or so.
At my age I'm in a race to get to "the best I can be" before I hit the down slope of the age related performance curve on it's decline.
