THE LITTLE SWISS SISTER
The ultimate challenge for middle-distance runners, the OCC will start on a 55km course with 3,425 meters of positive elevation gain from Orsières, located in the south-western part of the canton of Valais in the Val d'Entremont.
This Swiss valley will amaze you with its unique landscapes: The OCC route will take you to the heart of this particular and typical nature before reaching Champex-Lac and Trient. You will then cross the Franco-Swiss border by the emblematic Balme pass and its sublime panorama on the Mont-Blanc massif. Once you have reached the last difficulty of the course and the ascent to La Flégère, you will only have to enjoy the descent and savor your performance by crossing the mythical finish arch in the center of Chamonix under the cheers of families and spectators.
