What awaits you

You'll pass through

Mont-CrosinSentier du SergentCombe-GrèdeChasseralMont-SujetSentier des statuesPrés-d'OrvinBise de Corgémont

A demanding course on the edge of ultra-trail, for trail runners looking for a challenge and big landscapes.

You set off from Tramelan by the light of your headlamps and climb the ridges to the Mont-Crosin wind farm. The Sergeant's Trail takes you down to Saint-Imier and Villeret, then the Combe-Grède trail leads you up to Chasseral.

You head back down to Nods and tackle the Mont-Sujet hump towards Lamboing. The return leg climbs steeply via the Statues Trail and Prés-d'Orvin, then heads for Cortébert.

All that's left is the last steep climb up to the Bise de Corgémont. After that, it's downhill to Tramelan and the finish.
