Chamrousse, stage 13

The climb to the ski resort of Chamrousse is one of five summit finishes in the 2014 Tour de France.

The climb has only been used once in the history of the Tour, when Lance Armstrong won a mountain time trial on the ascent in 2001, clocking one hour, seven minutes and 27 seconds.

This time round the ascent, close to Grenoble, will come at the end of a 197.5km stage, the first in the Alps, and after the category three and one climbs of the Col de la Croix de Montvieux and Col de Palaquit respectively.

The 18.2km climb is the second-longest in this year’s Tour and the first hors categorie ascent to feature on the 2014 route, averaging 7.3 per cent and likely to see the race spark into action.
