Saturday June 20, 2026:

Resort Trail: 8 with 350D+ to gain height and discover this resort with a magnificent view of the Dent d'Oche.

Sunday June 21, 2026:

Trail de la Dent d'Oche: 21km with 1400D+. A trail to enjoy and discover the whole Oche valley. A passage over ridges and an incredible view of the lake and Mont Blanc make for a magnificent loop.

Trail du Châlet d'Oche: 30km with 2400D+ A mythical distance in a dream setting... A trail with highly technical sections, big climbs, but also very rolling sections. This trail takes in much of the magnificent scenery of the weekend's other races.

La Balade Chablaisienne: 62km and 4400D+ Because we like to keep the fun going, and because there are so many wonderful places in the Chablais region that we want to show you, we're bringing you this year's Balade Chablaisienne.

La Balade Chablaisienne Relais: 62km and 4400D+ New Bernex Trail Challenge route. What better way to enjoy the Balade Chablaisienne than as a team. Two runners to complete the course: the first runner will complete 33km and 2400m of D+ and the second runner 28km and 1800D+.
