I'm no Lance Armstrong, in fact, I'm no Lance anything, but I have been at the back of a large pack of inexperienced riders before (due to an equipment failure, but that's another story). Wobbling from side to side, jumping off to push their bikes up the slightest incline, not paying attention to anyone around them except their girlfriend riding next to them on a shoulder wide enough for only one bike. You really have to keep your wits about you. But hey (in this case) each of them raised a bunch of money for the charity and they are out there on a bike. I still love 'em. Even admire them for attempting something out of their comfort zone.
