The 26km trail run offers a great number of mountainous landscapes.
Starting on a small single in a larch forest, riders then cross terraced mountain pastures before arriving at a mountain lake. The second part of the course features a beautiful panorama of the Meije and a descent along a ridge line overlooking the canton. Competitors then switch to an isolated, wild valley, before a final descent through slate to the village of La Grave. This wild and varied route is in keeping with the spirit and climate of the Meije region.
