Waterside between Río Riaza and Río Duero

The ride

Roll out of Hoyales de Roa and the unpaved tracks take over almost at once, carrying you along the Canal de Guma. The route then follows the Río Duero and later the Río Riaza, each river marking another stretch of the loop. With 582 m of climbing spread across the ride, the pedalling stays honest, and the return brings you back to where you started.
