A long, treacherous mountain stage to Peñas Blancas, high above the Costa del Sol.
The first seventy kilometres are flat, but then come three climbs in a row on the way to the uphill finish at Peñas Blancas, above Estepona. Exactly the kind of stage where you can lose the Vuelta but not win it.
With the Vuelta's toughest mountain stage on the schedule the very next day, the favourites will try to save energy here without getting caught out by a cunning attack.
Over 5,000 metres of climbing, five categorised ascents and a final climb averaging nearly 10 percent: stage 20 is the toughest day of the 2026 Vuelta.
The only long time trial of this Vuelta lived up to the billing. Stefan Küng powered to victory on the flat, wind-exposed 32.1km course from El Puerto de Santa María to Jerez de la Frontera, beating his Red Bull-BORA-hansgrohe teammate Callum Thornley by three seconds and João Almeida by nine. But the day belonged to Enric Mas: riding the time trial of his life, the race leader conceded just 33 seconds to Primož Roglič, who moved above Felix Gall into second overall but still trails the red jersey by 1:37 with two mountain stages left. Gall lost nearly a minute and a half to Roglič on the stage and slipped to third at 3:01. The full story of stage 18, the general classification after eighteen stages, and a look ahead to Friday's mountain stage to Peñas Blancas.
The first mountain day of a brutal closing weekend produced this Vuelta's most dramatic finish yet. A breakaway containing Eddie Dunbar, Santiago Buitrago, Tom Gloag, Urko Berrade and Marcel Camprubí escaped over the stage's early climbs and held its lead all the way to the base of the Peñas Blancas summit finish. Buitrago attacked first and looked set for a solo win, but Dunbar hauled him back and swept past with roughly 350 metres to go, taking his first stage win of this Vuelta by 14 seconds. Behind them, Primož Roglič tested Enric Mas with a late dig, but the race leader answered without difficulty and the entire top five — Mas, Roglič, Felix Gall, Richard Carapaz and Oscar Onley — crossed the line together, some five minutes down, with the general classification completely unchanged. The full story of stage 19, the standings after nineteen stages, and a look ahead to Saturday's brutal queen stage through the Sierra Nevada.
