Maraton de Montaña Los 10000 del Soplao 2026

The 10,000 of Soplao BTT is a 163 km mountain-bike cycling march held in Cabezon de la Sal, Cantabria, northern Spain. Taking place in May, it follows the Spanish BTT format, meaning Bicicleta Todo Terreno: off-road, all-terrain riding, not a standard road sportive. The event serves as a meeting point for sport, tourism, and nature, fitting its Cantabrian setting near mountains and the coast. Starting in Cabezon de la Sal, the distance alone ensures it is a long day for participants focused on endurance cycling rather than a short local ride.
