Marathon du Montcalm

About the Event

Confront the mythical high-altitude trails of the Pyrenees at the Challenge du Montcalm, a legendary ultra-trail and mountain running festival celebrating its 36th edition in Auzat, Ariège, from 13-16 August 2026. This is the home of the epic PICaPICA, a 109km odyssey with 11,500m of ascent traversing France and Andorra above 3,000 meters, alongside its formidable siblings: the 70km PicAriège, the 40km Marathon du Montcalm, and a full spectrum of races from a vertical kilometer to a festive night run. More than a competition, it's a profound human adventure powered by nearly 700 passionate volunteers, offering an unparalleled blend of extreme challenge, breathtaking scenery, and warm, convivial community spirit in the heart of the mountains. With registrations opening on 11 December 2025, prepare to test your limits on some of Europe's most revered and demanding mountain routes. Join the Montcalm family for an unforgettable experience where every step is a legend in the making.
