About the Event

Escape into one of the Jura's most breathtaking natural amphitheaters at the **Trail du Cirque du Fer à Cheval on Saturday, March 21, 2026**. Set in the heart of Arbois, the capital of Jura wines, this wildly popular event invites runners to traverse the dramatic limestone cirques and vine-clad valleys that define this UNESCO-worthy landscape. With five demanding distances ranging from a welcoming 10km to the monumental 84km ultra featuring 3,500m of elevation gain, the course delivers a complete immersion into the region's rugged beauty. Each route winds through private forest paths and panoramic ridgelines granted exclusively for race day, offering perspectives of the Fer à Cheval cirque that few ever witness. It is a celebration of Jura's wild soul, timed impeccably for the first flush of spring.
Demand for this event speaks for itself: the 84km, 46km, 32km, 22km, and 10km trails have already reached their 500-runner capacity, closing registration well in advance of race day. Only the 10km marche-randonnée and limited camping emplacements remain available, a testament to the fervor this event inspires among Franc-Comtois trail devotees and UTMB points seekers alike. Organizers have meticulously structured each course with generous cutoffs, frequent liquid and solid aid stations, and the option for 84km runners to bifurcate onto the 46km course at kilometre 42—a compassionate nod to the unpredictability of ultra-distance racing. Every participant is encouraged to secure the optional cancellation insurance during registration, ensuring peace of mind against the whims of weather or circumstance.

The race weekend unfolds from the Camping au cœur des vignes, where the scent of Savagnin hangs in the air and the distant profile of Mont Poupet beckons. Here, trail runners, hikers, and their families converge for a communion of effort and terroir. The 6:00 AM start for the 84km sees headlamps bobbing like fireflies into the darkness, while the 10km runners depart at 10:30 under full morning light, sharing the same finish line and the same profound sense of accomplishment. With 500 bibs per distance and a strict cap, the Cirque du Fer à Cheval has earned its reputation as an intimate, high-quality event where every runner matters. Secure your remaining spot now for the randonnée or pitch your tent among the vines—the Jura awaits, and its horseshoe-shaped cirque will leave its mark on your memory long after your legs have recovered.
