Hills between the Río Guadarrama and Río Aulencia

The ride

This ride rolls out of Las Rozas de Madrid and back again, 55.7 km with 698 m of climbing along the way. Most of it runs unpaved, so expect plenty of dirt under your wheels between the paved stretches. You pass the Río Guadarrama, then follow on to the Río Aulencia before turning for home. Two rivers, one loop, and a steady climb to keep the legs honest.
