A stage consisting in a little over 150 km, with an elevation gain rarely seen before in La Vuelta. Special category climb and La Vuelta 21 Alberto Fernández peak: 15 km at the unprecedented Altu d’El Gamoniteiru, with a constant climb featuring an inclination of 10-12%, will offer one of the race’s greatest spectacles. Before that, the Puertu de San Ḷḷaurienzu (1st cat), the Altu de La Cobertoria (1st cat) and the Alto la Segá or del Cordal (2nd cat), will impair the riders’ strength as well as their legs.
