I've joined a team, the Hardly Davidsons, that's going to ride a 100K race to raise money for diabetes research. I was a little concerned since I've never ridden 100 anything, I told our team captain, "I don't want to be the one the holds the team back, but I start out slow, and don't finish." She said that was fine; the race organizers don't monitor the teams. Once you've paid your entry fee and raised your donations you can come to the picnic at the end even if you never start.
That's not what made America great, but then neither am I.
