Trail Zapallobos 2026

Trail Zapallobos begins and ends in Tremor de Arriba, a village in El Bierzo, province of León, Spain. This June mountain-running event offers three choices: a 24 km trail race, a 14 km trail race, and a category for walkers. The race is organized by Club Deportivo Atlético Aguzo, specifically its mountain section. Registration is online, all three race options have the same fee, and a paid meal is available for companions, giving the day more of a local club-event atmosphere than a runner-only checkpoint affair.
