The second Alpine stage of the Tour de France is short, nervous and very difficult. Right from the start, stage eight commences with rollers that will be ideal for attackers, then it transitions to three first category ascents in the second half. After 75 kilometres, the long ascent of the Cormet de Roselend, then the Montée de Hauteville should give the favourites a chance to get into position for the 18-kilometre, 5.5% average gradient of the ascent to Tignes, where the real contenders for victory in this year's Tour will likely be revealed.
