La 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.
