Water route between Río Aranzuelo and Río Gromejón

The ride

Roll out of Gumiel de Izán and the road soon leads into the Sabinares de Arlanza-La Yecla nature reserve, with 77.5 km of paved riding ahead. From there the route follows the Río Aranzuelo and later the Bañuelos, both rivers shaping the way. The Río Gromejón joins the story before the loop turns back toward Gumiel de Izán. With 598 m of climbing spread across the day, it's a route that keeps unfolding.
