X-Alpine 68 MI 27'600 ft

THE main Swiss Alps trail, X-Alpine will take you through the best viewpoints of the area, with a cumulative positive drop of 27,600 ft. This new route is definitely alpine and will become a real challenge for experienced ultratrailers.

The route joins the 3 valleys of the river Dranse, forming a symbolic link between these three geographic regions. Two main uphills will harden the beggining , passing by the top of Catogne (2598m), with a breathtaking view and by the Orny hut (2826m), by a glacier. From La Fouly the route remains unchanged and goes towards the passes of Fenêtre and Gd St Bernard. Some stops in picturesque villages will allow you to refill your stock power to run across the last passes and the last steep ascent to La Chaux. Quite technical and steep, these last 4,000 feet will certainly call for another huge effort from the runners. At the summit of this section, victory is getting within sight: the final kilometers on the flat will stretch the groups of runners out along the "bisse" before the final descent to the Finish line. The first arrivals might still catch a glimpse of the majestic Combins mountains, while the rest of the pack will run by the light of their head torches lighting the path and creating a magical scene under a star-lit sky.




Verbier (Place de l’Ermitage, next to Central Place), 8 July 2017, 1:00 and 4:00 am.
