Today the peloton moves towards the Cantabrian mountains. After a long and technical descent the Alisas will narrow down the group. The final climb is very rough and irregular. It has never been in a race before. The riders will be welcomed by the monument to the Pasiega cattle.
Fernando Escartín commentary:
Mountain. Castille will bid farewell to the peloton with a simple start to the stage, followed by almost 3,000 metres of slopes. The spectacular descent from La Lunada, that will lead straight onto the Alisas mountain pass, and the final climb up the infernal Los Machucos slopes will really test the peloton's strength.
