Treparriscos

The Treparriscos is the "lighter" version of the Quebrantahuesos: about 85 km with ~1,350 m of climbing. It features the Cotefablo pass (~13.7 km at 4.4%) as the key section where differences are made. To tackle it confidently, train 10-15 km climbing efforts, manage your pace on moderate ascents and control energy expenditure on smaller climbs before Cotefablo.
