Ber’neX Trail Challenge

The Ber’neX Trail Challenge offers a demanding and striking journey through the rugged terrain of the Chablais region in France. The main event covers 62 kilometers with a grueling 4,300 meters of elevation gain, challenging runners with its technical ascents and tricky forest trails. The race winds through deep gorges, alpine ridges, and rocky paths, offering runners a true mountain adventure. Shorter options like the 30 km route, which still offers a tough 2,100 meters of elevation, make the event accessible to a broader range of runners. The 21 km race, with 1,400 meters of elevation gain, is perfect for newcomers or those looking for a fast-paced, picturesque route through the Jura’s forested paths. In addition there is a shorter 8 km race as well as a children’s event.
