Bernese Jura Trail

The Grandiose is a demanding route for trail runners looking for challenges and sumptuous landscapes. A course on the border of the ulta trail awaits you with La Grandiose. The departure from Tramelan by the light of headlamps begins with a steep climb on the ridge and a descent to Cortébert which will immediately break a few muscle fibers. Then direction Mt-Sujet and Lamboing to go back to the summit of Chasseral. From there, the path takes you downhill into the heart of Combe-Grède to then go up on the other side of the St-Imier valley to the Mt-Crosin wind farm. One last effort because in the distance, Tramelan and the finish await you.

The Essential is a route which condenses the most beautiful sites of the Bernese Jura, hence its name. This L'Essentielle course requires good physical preparation for those who wish to take on a challenge by covering a distance close to a marathon but in the heart of nature, with added elevation. After a steep climb on the ridge, a steep and rapid descent to Cortébert which can leave traces. The path then takes you to Chasseral and its antenna to descend via the magnificent Combe-Grède via a technical path. From St-Imier, go up the Col du Sergent to arrive at the Mt-Crosin wind farm and its welcome refueling. Last effort to finally reach Tramelan and the finish line.

The Crossing largely follows the route of The Essential race but without the climb to Chasseral. The Traversée route begins with a steep climb on the ridge and a steep descent to Cortébert and the 1st refreshment point. Quiet passage along the river, ideal for restarting the machine. Hilly climb to St-Imier and big climb of Col du Sergent to arrive at the Mt-Crosin wind farm. Last effort to reach Tramelan and the finish line. NB La Traversée is now part of the Grand Chasseral Trail Series with the Villeret-Chasseral-Villeret race and the 7 Lieues trail (course des Pavés).

La Découverte is a short but nervous route which begins directly with a sharp climb in a straight line towards Les Bises de Corgémont. After a winding passage in the woods, a slight climb at the edge of the forest before a steep but not technical descent towards the St-imier valley. Halfway up, flat passage ideal for restarting before tackling the last difficulty with the climb towards the ski club chalet on the ridge. Then follows the descent towards Tramelan via picturesque paths and it is already the finish line.
