Course
The Trail du Mercantour is a 72-kilometer trail race with 4,500 meters of elevation gain, taking place in the Mercantour National Park in the Alpes-Maritimes. The start and finish are in Saint-Martin-Vesubie, a mountain village nicknamed the "Swiss Riviera," perched at 1,000 meters altitude in the Vesubie valley. This race is an immersion into one of France's most biodiverse national parks, a territory where the Alps meet the Mediterranean in a striking contrast.
The Mercantour is an exceptional massif. The last alpine bastion before the Mediterranean, it harbors extraordinarily rich fauna and flora. Wolves, which naturally returned from Italy in the 1990s, are the park's most famous residents. Chamois, reintroduced ibex, golden eagles, and bearded vultures populate these mountains. The flora includes more than 2,000 species, many of them endemic. Running through the Mercantour is to cross a sanctuary of living nature.
The 72-kilometer course explores the heart of the park, following trails that wind between intensely blue altitude lakes, larch forests ablaze with color in autumn, flower-filled alpine pastures, and panoramic ridges. Runners cross several passes situated between 2,200 and 2,700 meters altitude, offering spectacular views of the Vesubie and Tinee valleys and, on clear days, the shimmering Mediterranean to the south.
The 4,500 meters of elevation gain reflect the impressive verticality of the Mercantour. Valleys are deep, slopes are steep, and passes are high. Climbs are long and demanding, often on stony trails exposed to the sun. Descents, technical and sometimes vertiginous, follow narrow trails carved into steep slopes. The terrain is typically southern alpine: metamorphic rocks, schist, and gneiss, with passages over smooth slabs and unstable scree.
The Mercantour's distinctive feature is its proximity to the Mediterranean. This maritime influence translates into exceptional luminosity, sometimes near-tropical flora in the lower valleys, and weather conditions that can combine intense heat with violent storms. Runners may start under blazing sun only to find themselves hours later in fog and rain at altitude. This Alps-Mediterranean combination is unique and adds a fascinating element of uncertainty.
Saint-Martin-Vesubie is a characterful village that hosts the race with fervor. Its medieval lanes, fountains, and colorful facades create a charming setting for the start village. The local gastronomy, influenced by proximity to Italy and mountain traditions, is generous: Swiss chard pie, socca chickpea flatbread, raviolis in beef stew, and mountain cheeses fill the aid station tables.
The Trail du Mercantour is aimed at experienced trail runners seeking alpine beauty in its most southern expression. It is a race where the mountain dons the colors of the south, where light is golden, where the fragrance of lavender mingles with the freshness of altitude. The Mercantour is a treasure of the southern Alps, and this race is the finest way to experience it.
