Xterra Trail Vallée de Joux

In the heart of the Vaudois Jura, between deep forests, open pastures, and wild ridges, the XTERRA Trail Vallée de Joux is an alpine adventure just the way we like them: raw, authentic, and rooted in nature. Here, the trails wind between lakes, skirt the forests of the Vaudois Jura Park, and reveal the Valley's unique atmosphere: a striking calm, cut short by the runners' breath and the clicking of poles on stones.

What you'll find there

• A Swiss atmosphere on a human scale, both warm and challenging.
• A trail village where elite runners and runners come for fun mingle, smiling volunteers, a hot coffee before the start, and a well-deserved meal at the finish.
• All this in an unspoiled natural setting, where each bend in the trail immerses you a little deeper into the Jura mountains.

Course Focus

Five distances, five ways to experience the Vallée de Joux.

• The 6 km for beginners on an accessible and smooth route.
• The 12 km and 22 km for experiencing the slopes, skirting pastures, and flirting with wooded ridges.
• The 36 km for a complete, varied, and demanding loop, with long forest sections and open lake views.
• And the 68 km, an iconic format, designed for those who love pure effort: 100% nature, 100% Jura.

All courses are run semi-autonomously, with a limited number of aid stations—here, the trail spirit takes on its full meaning. No disposable cups, no unplanned assistance, and absolute respect for the mountains: we run light, responsibly, and leave with our eyes full of green.

The XTERRA Vallée de Joux Spirit

This is a trail that people return to for the beauty of the setting, but also for its balance: rigorous organization, a true race ethic, and that Swiss-style friendliness found nowhere else. Here, we don't seek to beat the others, but to find our rhythm among the fir trees, to master the climbs, and to savor each descent toward the Trail.
