We call it the bonk. Trust those Frenchies to have a poncey word for it. Défaillance. Huh. Theirs of course also means a mental collapse, as well as just a physical one.
Poncey as the word is, looking across the last few days of le Tour, I reckon it could become the word to define the 2010 edition of the race.
So here's the question: who do you think has défailed themselves the most so far? Armstrong? Wiggins? Evans? Millar? AN Other?
