XTerra Trail Vallée de Joux

The XTERRA Trail Vallée de Joux returns in 2026 for its 17th edition, set in an exceptional natural setting amongst forests, pastures and the shores of Lake Joux.

On Saturday 10 October, it’s the turn of the youngest participants and short-distance enthusiasts, with children’s races – a 6 km and a 12 km – through the magnificent landscapes of the Vallée de Joux.

On Sunday 11 October, the serious competition begins with three iconic routes:

58 km for the most seasoned competitors,
36 km for a sustained challenge,
22 km for a more accessible format.

On Saturday 10th, the races will start from Le Sentier, and on Sunday 11th, they will start from the Abbey, on the shores of Lake Joux – a magical spot that perfectly embodies the XTERRA spirit: authenticity, nature and pushing your limits.

Whether you’re a keen runner, a thrill-seeker or simply a nature lover, the XTERRA Trail Vallée de Joux is an unmissable event not to be missed!
