I am not saying they have to do that route but can't see why they couldn't have gone down this mountain they are doing and then back up or to something else to make the stage longer and be more of a test.There;s literally no other way to get to Val Thorens from Albertville. You go down the N90 or you go over the Cormet de Roseland into Bourg Saint Maurice. At the op of the Cormet there is another tiny road to take you back to the D90 but if you can't get to the top then that's not so important.
