Maratón BTT Sierra del Arca

Maratón BTT Sierra del Arca is a mountain bike marathon held in San Roque, within the Campo de Gibraltar region of Cádiz. It takes place in late October and is part of the XCM Series Cádiz, the provincial cross-country marathon series for mountain bikers. The event starts from Estación de San Roque and provides two BTT route choices: 67 km and 42 km. Both distances are designated as non-competitive, focusing the day on enjoying the Sierra del Arca terrain rather than pursuing an official race time.
