At the start of the 2006 Toronto Ride for Heart I was so pumped for the start of the 75K that I clipped my feet in and started off with a great hammering cadence.....only to find after about 100m that the entire mass of cyclists (this is the start remember, around 10,000 bikes!) stopped due to a bottleneck in the way. You guessed it, I failed to execute the unclip and toppled over nearly causing a 10,000 person domino unclip topple over. Do I win for having the most witnesses??
