Confines de la Sierra Bike Maraton

Confines de la Sierra Bike Marathon is a true BTT marathon held in Nerpio, in the Sierra del Segura on the southern edge of the province of Albacete. The event offers two formats — the full Confines marathon and a shorter Confines Sprint — across rocky mountain terrain on the border between Castilla-La Mancha and Andalucía. Riders enjoy long climbs and technical singletrack through one of the most remote and best-preserved corners of the Iberian Peninsula.
