None of the contenders for the yellow jersey can afford a slip-up today. The climbs are tightly packed, starting with the Montvernier hairpins, then continuing with the crossing of the Télégraphe and Galibier passes. After passing through Serre-Chevalier, 10 kilometers of climbing at an average of more than 9% remain to reach the 2,413-metre Col du Granon, which was the Tour’s highest finishing point for 25 years.
