Stage 18

Thursday September 12 2019 - Colmenar Viejo to Becerril de la Sierra - 180.9 km
 

A very hard stage, similar to the one in which Fabio Aru managed to overtake Dumoulin as race leader in La Vuelta 15 with only one stage left. The climbs involve the mountain passes of Navacerrada, La Morcuera on both sides, and Cotos, from where the race will continue downhill to the finish in Becerril de la Sierra.
