Le Casse-Pattes des Tourbières

The Le Casse-Pattes des Tourbières returns for its 8th edition on Sunday, April 26, 2026, in the scenic village of Clarens, France. This event is known for its friendly, high-energy atmosphere and routes that showcase the unique peat bog (tourbière) landscapes of the Hautes-Pyrénées. The race offers a variety of challenges, from technical trail runs with significant elevation gain to family-friendly marches and children's races. Participants are encouraged to embrace the local terrain, which is designed to be both physically demanding and visually rewarding, finishing with a celebration of the regional natural heritage.

Clarens is situated in the Plateau de Lannemezan within the Hautes-Pyrénées department. Geographically, the area acts as a gateway to the Pyrenean foothills, characterized by its unique humid zones and high-altitude bogs that are rare in the region. The landscape features rolling hills and dense woodlands, providing a varied underfoot experience for runners. In late April, the climate is typically fresh and maritime; average daytime highs reach 15°C (59°F), while the humidity of the peat bog environment often leads to damp morning trails and misty conditions around the 7:00 AM start time.

The event logistics are managed by the Pyrénées Chrono platform, ensuring professional timing and digital results for all competitive categories. Registration is accessible online, with the central hub located in Clarens for bib pickup and post-race festivities. The program is specifically structured to welcome all ages, with the youth race aimed at participants between 7 and 14 years old. While the 19 km and 12 km trails are timed for competitive runners, the 7 km march provides a non-competitive option for those wishing to appreciate the environmental significance of the local tourbières at a more relaxed pace.
