Trails des Balcons de Cauterets is a late-June mountain trail series held in Cauterets, a village in the Hautes-Pyrénées of southwest France. Runners begin at approximately 1,000 meters above sea level. The event is situated near the Pyrénées National Park and features several distances, ranging from approximately 11 km to ultra-style options around 80 km. The shorter races involve significant climbs: the 11 km route has about 500 meters of elevation gain, the 20 km version around 1,200 meters, and the 47 km race roughly 3,000 meters, with the longest option exceeding 5,000 meters.
The courses traverse rocky trails between high passes, with rivers, green slopes, and mountain terrain influencing the race more than speed. The highest point mentioned is the Col de Lisey, and participants also pass near Lac de Nère, incorporating exposed climbs and waterside sections. This event suits individuals seeking a genuine Pyrenean trail experience over a flat road race. Local runners, mountain specialists, and visitors balancing distance with significant elevation are all welcome.
