Puerto de Estacas de Trueba, 3ª (km 118): 1.140 m – 11 km – 3 %
Puerto del Escudo, 1ª (km 158,5): 1.010 m – 7 km – 9 % (not counting previous false flat)
Alto Campoo – Fuente del Chivo, Es (Meta): 1.990 m – 18 km – 5,6 % (another hilarious categorization)


The longest stage of this Vuelta and the start of a very important tríptico, but I would be very surprised if anything significant happened here. Final climb is too shallow and very exposed to the wind.
Looks good for a break away.
