Trail de la Tarentaise

The Trail de la Tarentaise is a 42-kilometer trail race with 2,600 meters of elevation gain that takes place in the Tarentaise valley, in the Savoie department, starting from Moutiers. This legendary valley in the French Alps, crossed by the upper Isere river, is one of the most famous mountain regions in the world, home to internationally renowned ski resorts such as Courchevel, Meribel, La Plagne, and Les Arcs.

Moutiers, the starting point of the race, is a historic thermal town located at approximately 480 meters of altitude, at the confluence of the Isere and the Doron de Bozel rivers. This valley-floor position gives the race a distinctive character, as runners start from a relatively low altitude and progressively climb toward the summits. Moutiers is also an ancient episcopal city, whose Cathedral of Saint Peter bears witness to a rich religious and cultural past.

The 42-kilometer course winds through the characteristic landscapes of the Tarentaise. The valley is framed by two major massifs: the Vanoise to the south, with its glaciers and peaks exceeding 3,000 meters, and the Beaufortain to the north, a gentler massif with vast alpine pastures. Runners cross mixed forests of broadleaf and coniferous trees, then alpine meadows where Beaufort and Tome de Savoie cheeses are produced, protected designation of origin products that define the gastronomic reputation of the region.

With 2,600 meters of positive elevation gain, the Trail de la Tarentaise offers a demanding yet accessible profile for runners with solid mountain trail experience. The climbs are varied, alternating between steady gradients on forest trails and steeper sections in the high-altitude pastures. The descents follow technical trails that demand vigilance, particularly in the wooded sections where roots and rocks can prove treacherous.

The Tarentaise benefits from a distinctive mountain microclimate, with summers generally warm in the valley floor and cooler conditions at altitude. Sunshine is good thanks to the east-west orientation of the valley, but afternoon thunderstorms remain frequent during the summer period. Runners should plan for equipment adapted to temperature variations between the valley floor and the high points of the course.

For international runners, Moutiers is remarkably well served. The Moutiers-Salins-Brides-les-Bains train station is an important railway hub, served by direct TGV trains from Paris, Lyon, and other major French cities, particularly during the ski season. Chambery airport is about an hour away by road, and Geneva airport less than two hours. Accommodation options are abundant, ranging from hotels in town to rentals in the surrounding resorts.

Assistance on the Trail de la Tarentaise is an appreciable advantage for runners. The valley's configuration with its multiple access roads allows an assistant to reach several points along the course. Local knowledge of access routes, terrain conditions, and the specific weather patterns of the Tarentaise can prove decisive for adjusting race strategy in real time.

The Trail de la Tarentaise is an event that combines the wild beauty of high Savoyard mountains with the accessibility of a marathon distance. It is an ideal race for runners who wish to discover the Savoie Alps in a demanding yet human sporting context, in the heart of a valley whose natural and cultural richness never ceases to amaze.
