Very physical course reserved for experienced runners looking to train for competition. It is the very authentic spirit of the trail that characterizes this loop.

Very wild and majestic, it allows you to reach sites such as the Col de Véry, the Col du Joly, passage under the Col de la Fenêtre and Lac Noir. The route is characterized by a multitude of small climbs and descents over two-thirds of the route to Pas d'Uutray. From there, a long descent of more than 1000 m of vertical drop to the foot of Hauteluce takes you back to the slope of Les Saisies and ends on a last steep climb of 600 m of D +. You will evolve near pastures, stay on the trails, and respect the work of the mountaineers.
