. On Saturday, American David Zabriskie plans to try something entirely new: Riding the Tour on a vegan diet.
Experts say he is the first cyclist to attempt the most difficult bike race in the world sans meat, dairy or eggs. (He will cheat slightly, he says, because he plans to eat small amounts of salmon two days per week to increase iron absorption).
So, it won't be a first then. If he's eating salmon to get through it he's just saying it's not possible to do it on a vegan diet.
