From the resort of Oz en Oisans, you will head towards the charming village resort of Villard Reculas. You will then set off through the mountain pastures of this family resort to reach the village of Huez, then the resort of Auris en Oisans.

Then, you will start the first difficulty in the direction of the authentic mountain village of Besse en Oisans and its mountain pastures. Your ascent will then continue towards the Plateau d’Emparis where you can enjoy wild and preserved mountain landscapes without forgetting the imposing and mythical Meije glacier.

Following this first difficulty, you will descend a second time to Besse en Oisans before encountering a second difficulty that will take you through mountain villages: Clavant-le-Bas and Clavant-le-Haut to the Col de Sarenne.

After the pass, you will reach Alpe d’Huez and then the resort-village of Vaujany via La Villette. Finally, the crossing of the Plateau des Lacs before your passage to Vaujany will allow you to enjoy a splendid view between lakes and mountains.

For the last few kilometres of the course, you will set off in the direction of Oz en Oisans where the finish line will be located.

As we are working in natural areas, living together with people who use the land you are walking through all year round, we sometimes have to make changes to our different routes, which may slightly modify the distance and/or the height difference. This distance and difference in altitude are therefore given as an indication.
