Well, I gotta say that the effect this was supposed to have is kind of disappointing... apart from the fact that maybe they ride a little slower and are more afraid of attacking and blowing up.
The only "star" who really can't handle it seems to be Andy Schleck... quelle surprise.
I've said it a number of times, and I will say it again. Unless you have experienced going into oxygen debt at altitude, you have no idea how long it takes to recover. It is essentially going anaerobic with out doing anything. When you feel it coming on, you dial back to a less threatening aerobic level of riding, and it is a whole lot slower.
Decades ago, when I lived in Durango I was invited by several friends to do the Durango-Silverton-Durango century. Two of these guys were Cat 1/2's. And while I was one of the stronger Mtn bikers in town, I made the mistake of trying to follow up and over Coal Bank Pass (10640 ft./3243 m.). For the last two miles it was all I could do to pinball the rest of the way up. Not a bonk because with their encouragement (and indulgence), I finished the century (over Molas to Silverton, and back over Molas and Coal Bank).
Redlining on a mountain bike at altitude is much more stark (and yes, I've done this a number of times primarily due to the fact that to clean a particular section, you have to go anaerobic. The bottom line is that you really have to mete out your efforts wisely. As someone mentioned upthread, will be no hiding today - we will know who went out too quickly - and there will be some large time gaps.
