One year, Tyler Hamilton finished the race with a broken collarbone. He crashed in the tail end of the first week, just before the mountain stages. These cyclists will go on with one leg sometimes. The second stage this year, that young frenchman going up a cat 4 with one hand, the other hanging down because it was too painful to have it on the bars with his fingers dislocated. It's been said that if you're a professional cyclist you are going to it the pavement, hard, at some point in your career.
It takes a different sort of animal to get into those mass sprint finishes on the 'straight bits'. Cavendish's helmet looked a mess, imagine if he wasn't wearing it.
I like the mountain stages, the agony of the guys going up, steeper and steeper. Then the descents, flying down like madmen. Some are better descending than ascending. Throw some rain into the mix and it's really crazy.
