Trail des Baous takes place the weekend of July 15-16 in Saint-Jeannet, organized by Longo Trail. It offers mountain running above the French Riviera, distinct from a flat road race. The primary trail events are a 42 km with 2,200 m of elevation gain and an 18 km with 850 m of gain, providing options for a long mountain run or a shorter, hilly trail race.
The routes are set between the Mercantour mountains and the Mediterranean Sea, with views toward the Esterel massif and the Italian coast. The weekend also features the Foulée des Baous races alongside the main trail challenge: a 10 km with 250 m of climbing, a 5 km with 120 m of climbing, and children's races. This format establishes it as a local running festival rather than a singular event.
