 The fifth stage was the first to be categorised as a mountain stage , with a summit finish at the ski resort of Valmorel , just outside Les Avanchers . After an opening loop around the start town of Grésy @-@ sur @-@ Aix , the Côte de Trévignin was the first of four categorised climbs on the day 's route . The climb of 4 @.@ 4 km ( 2 @.@ 7 mi ) averaged 6 @.@ 6 % over the ascent , and from there the race progressed to the Massif des Bauges . After a period of undulating terrain , the short , sharp fourth @-@ category Col du Frêne was next on the route , at 6 % over just under 2 km ( 1 @.@ 2 mi ) of climbing . After the descent down to Saint @-@ Pierre @-@ d 'Albigny , the 139 km ( 86 @.@ 4 mi ) parcours headed towards Valmorel via Albertville , the intermediate sprint point at La Bâthie and the fourth @-@ category Côte de la Croix . The final climb , an hors catégorie ascent , averaged 7 % over 12 @.@ 7 km ( 7 @.@ 9 mi ) , which was somewhat ameliorated by several hairpin bends towards the finish , which provided any attacking rider with a perfect kick towards the finish .
