In the criterium at Chattanooga this past weekend, I was just hanging out on the last lap. I wasn't going for a stage win or anything, just trying to stay close to the front and out of trouble. There was a crash with half a lap to go and I was right behind it. Grabbed a fistful of brakes and was coming to a stop on my front wheel. . .but not quick enough. I was not going to be able to stop before hitting the guy on the ground in front of me.
So, at the last second I unclip both my pedals, leap from my bike (still balancing on the front wheel), and jump over my handlebars, over the guy in front of me, and land on my feet running. I kept on my feet only putting one hand on the ground to keep my balance.
The bike got a little scratch on the seattube, but this was the luckiest "crash" I have ever escaped from. Now, if only somebody got it on video it'd make a great youtube video.
