Alpe d'Huez

One of the epic road climbs of the Tour de France. The average percentage of Alpe d'Huez is quite high at 8.1% with a length of 13.2 km and 1,071m. of climbing. But, isn't on paper at least, one of the toughest climbs. However, what Alpe d'Huez lacks in altitude and length is made up for in intensity. The climb is full-on from the bottom to the top with very little respite from the gradient or the heat bouncing off the south-facing, rock-lined road.
