I think he would probably like to win number 100 in the rainbow stripes before he gets the yellow jersey although either would be an iconic shot.He? The sponsors? Or the UCI?
Anyway, yeah, they definitely saved #100 for the TdF.
But once #100 is deemed to happen at the TdF, I don't think they care that much for it to be on an iconic climb.
I mean, what he is going to do?
Not win the ITT (even though Remco and others a way bigger favorites, there) or a hilly stage, only because they wouldn't be as iconic as it would be winning #100 on, let's say, Mont Ventoux?
