It's an interesting concept, and everyone has the right to take risks with their own lives if they so desire, but it seems obvious that these speed climbing stunts are going to lead to deaths...the caution required in such high risk environments does not lend itself to speed. Here's the last paragraph of the article:
This past June, Jornet and Stephane Brosse attempted to cross the entire Mont Blanc Massif in two days when Brosse broke through a cornice and fell 2000 feet to his death.
Tragic, but predictable. It didn't serve him right, but it could and should have been avoided. I don't think speed and icy alpine climbing environments are a good mix.
