Luchon Aneto Trail

The Luchon Aneto Trail is a cross-border ultra trail race of 85 kilometers with 5,200 meters of elevation gain, linking France to Spain across the highest peaks of the Pyrenees. The start is in Luchon, a historic spa town in the Haute-Garonne department, nestled at the end of a lush valley surrounded by summits exceeding 3,000 meters. The course leads runners to the foot of the Aneto, the highest point in the Pyrenees at 3,404 meters, before returning to France. This race embodies the very spirit of Pyrenean ultra trail: wild, demanding, and grandiose.

The cross-border nature of this event gives it a unique dimension. Runners cross the Franco-Spanish border via high-altitude passes, moving from the northern slope, humid and wooded, to the southern slope, more arid and mineral. This striking contrast between the two sides of the Pyrenees is one of the course's great assets. On the French side, beech and fir forests give way to lush summer pastures; on the Spanish side, landscapes become more austere, with deep valleys, immense scree fields, and glacial lakes of deep blue.

The 5,200 meters of elevation gain make this one of the most demanding races in the Pyrenees. The course strings together long, sustained climbs toward passes situated between 2,500 and 3,000 meters altitude. At these heights, the air thins, weather conditions become unpredictable, and the technical demands of the terrain increase considerably. Residual snow patches, unstable scree, and exposed ridges require solid high-mountain experience.

The proximity of the Aneto, the giant of the Pyrenees, gives this race a special aura. Even though runners do not reach the summit itself, they move through its immediate environment, amid residual glaciers, grandiose cirques, and moraines that testify to the power of geological forces. The panoramas are breathtaking: plunging views of the Maladeta massif, the Posets range, and the countless peaks bristling along the Pyrenean horizon.

Luchon, the start and finish town, is an ideal setting for this adventure. A renowned spa town since Roman times, it offers runners a remarkable heritage setting and quality infrastructure. The thermal baths allow ideal recovery after the effort, and the local gastronomy, from garbure soup to mountain cheese, restores energy with generosity.

Race conditions on the Luchon Aneto Trail are among the most alpine in the Pyrenees. The course's high altitude exposes runners to cold, wind, fog, and sometimes violent storms that break without warning in the mountains. The mandatory equipment list is substantial, and the ability to navigate in degraded conditions is a valuable asset. Time barriers are strict, reflecting the organization's seriousness regarding high-mountain risks.

This race is aimed at seasoned trail runners with solid high-mountain experience and excellent physical condition. The Luchon Aneto Trail rewards those who accept the challenge of confronting the mountain in its rawest and most authentic form. It is an exceptional Pyrenean crossing, a journey between two countries, two slopes, two worlds, united by the majestic chain of the Pyrenees.

Luchon Aneto Trail is a 85 km trail race with 5,200 m of elevation gain, located in Bagnères-de-Luchon, Haute-Garonne. The next edition is scheduled for 4 July 2026.
