The Ciclomarcha de Aveinte is a 50 km mountain bike ride based in Aveinte, a small municipality in the province of Ávila, Spain. It is run as a BTT event, using the Spanish term for off-road cycling, and it appears on the calendar in early October.
This is not a competition for rankings or prizes; the listed format is non-competitive. Riders start in Aveinte and cover a single 50 km distance, making it a straightforward local off-road cycling day rather than a multi-distance festival.
