The ride

Roll out of Gernika-Lumo and the road soon turns rough: 54% of this 60 km loop is unpaved. The route climbs for 2068 m, winding through Urdaibaiko Biosfera Erreserba, a nature reserve, before dropping toward the Butroe river. Follow the river's course, then spin the paved stretches back to where you started.
