ROUTE G4: SIERRA DE UBIERGO GRAVEL TOUR

This route starts from El Grado and goes around Sierra de Ubiergo, and it can be cycled in two ways. The first, you cycle the Alto de Torreciudad from its hardest and most challenging side, almost without a proper warm up. Afterwards you will descend the Alto de San Roque by a gravel road. The second way at the beginning is more gentle, climbing up the gravel road to the Alto de San Roque and ending up with a giddy down from the Alto de Torreciudad.
