Ultra Trail du Saint-Jacques by UTMB

The Ultra Trail du Saint-Jacques by UTMB is a 100-kilometer ultra trail race with 4,200 meters of elevation gain in the Puy-de-Dome department, in the heart of volcanic Auvergne. This event, part of the UTMB World Series circuit, is one of the benchmark races in French trail running, combining the mythical 100-kilometer distance with a course crossing the most beautiful volcanic landscapes of the Massif Central.

The Ultra Trail du Saint-Jacques course is rooted in the tradition of pilgrimage paths leading to Compostela. The trails follow portions of the Via Podiensis and other historic routes, connecting villages of character, Romanesque churches, and exceptional natural sites. This spiritual and heritage dimension adds unique depth to the sporting event, with every kilometer charged with history and meaning.

The 4,200 meters of elevation gain accumulate across a course traversing the main volcanic massifs of Puy-de-Dome. Runners climb the slopes of the puys, cross mountain forests, descend into valleys, and climb back toward new summits, in a succession that tests endurance and determination. Ridge passages, sometimes airy and exposed, offer grandiose panoramas over the Auvergne volcanoes.

The terrain is extremely varied, reflecting Auvergne's geological diversity. Trails alternate between basalt lava paths, forest tracks, high-altitude meadows, peatland and wetland passages, and dirt paths between pastures. The Massif Central's weather conditions, often changeable, add an extra dimension to the challenge, with possible passages through fog, rain, or wind.

The Ultra Trail du Saint-Jacques demands rigorous preparation and mastered race management. The 100-kilometer distance, combined with substantial cumulative elevation gain, requires a meticulously planned strategy for nutrition, hydration, and pacing. Time cutoffs, while reasonable, select out runners who progress too slowly.

Integration into the UTMB World Series circuit gives this race an international dimension. Runners from around the world come to attempt this event, which offers valuable qualification points for the UTMB in Chamonix. The atmosphere is that of a major international race, with a lively start village, renowned partners, and professional organization.

Aid stations, numerous and well-stocked, offer Auvergne specialties: Saint-Nectaire, Cantal cheese, truffade, Puy lentils, and mountain charcuterie. The volunteers' warm and caring welcome is precious support during the difficult moments of night and the final hours of the race.

The Ultra Trail du Saint-Jacques by UTMB is a complete event that deserves its reputation. The combination of a demanding course, exceptional volcanic landscapes, and high-level organization makes it an unmissable fixture in the French and international ultra trail calendar.

Ultra Trail du Saint-Jacques by UTMB is a 100 km trail race with 4,200 m of elevation gain, located in Le Puy-en-Velay, Puy-de-Dôme. The next edition is scheduled for 13 June 2026.
