The Ruta BTT dos Callos de Meis is a mountain-bike route in Meis, Pontevedra province, Galicia, starting at 09:00 in mid-July. It provides two off-road BTT routes, 40 km and 34 km, both designated as non-competitive, aligning more with a group cycling challenge than a competition for top positions.
The event, organized by Armenteira e Punto C.C., is at least in its tenth year. The participant limit is 500, with categories from Cadete and Junior to Elite, Sub23, Cicloturismo, and Masters up to Master 60, including women in various age groups. Riders with federation licenses have a reduced entry fee compared to those without, consistent with the Spanish cycling federation structure supporting the event.
