Trail du cirque du fer à cheval - Arbois 2027

The Trail du cirque du fer à cheval is a trail-running series held in Arbois, with races scheduled for a Sunday in March. It offers runners a range of mountain-style distances: 84 km with 3,500 meters of elevation gain, 46 km with 2,000 meters, 32 km with 1,400 meters, 22 km with 780 meters, and 10 km with 400 meters. The schedule begins early for the longest race, with the 84 km starting at 06:00, followed by shorter races throughout the morning. The two 10 km events share the same distance, climb, and start time, but differ in bib prices. The longer races' prices increase progressively from 22 EUR for the 22 km to 80 EUR for the 84 km.
