This new starting point will border the coastline along a winding route with short climbs well-suited to breakaways up to the only mountain pass of the day. Lagos de Covadona is, beyond a doubt, the most important mountain pass in La Vuelta’s recent history. This tough stage comes nearing the third week, which will be forcing the well-situated favorites to defend themselves and those who are not, to attack.

The climb to Lagos de Covadonga totals 12.6 kilometers, with an average 7.3% gradient. Within this pass, the La Huesera stretch is usually decisive, with an gradient of over 13% totaling over half a kilometer in length.
