La Grandiose is a demanding route for trail runners looking for challenges and sumptuous landscapes.
A course bordering on ultra-trail running awaits you with La Grandiose. The start in Tramelan, illuminated by headlamps, begins with a steep climb to the ridge and a descent to Cortébert that will immediately test your muscles.
Next, head towards Mont-Sujet and Lamboing before climbing to the summit of Chasseral. From there, the trail leads you down into the heart of the Combe-Grède valley before climbing back up the other side of the St-Imier valley to the Mont-Crosin wind farm. One last push, because in the distance, Tramelan and the finish line await.
