Stage 20

The road

At the start

Seven climbs, and Picón Blanco

Moncalvillo did it at last: Roglič attacked with six kilometres left, took the stage and the red jersey, and Ben O'Connor's thirteen days in the lead ended 1:54 down. Enric Mas is third at 2:20, Richard Carapaz fourth at 2:54. The last mountain stage carries seven classified climbs and more than 5,000 metres of climbing in 171 kilometres, and it finishes up Picón Blanco, whose ramps touch eighteen per cent.

How it was won

1. 1141 km to go

   An 11-man break over the early climbs

   On the brutal queen stage with over 5000m of climbing, a strong eleven-rider move led by UAE's Vine and Soler shapes up over the opening ascents.

2. 271 km to go

   Roglič's team crumbles

   Disaster for Red Bull on the hardest day of the race: Dani Martínez climbs off, Patrick Gamper follows him, and Nico Denz drifts out of the time limit — three team-mates lost in an afternoon, leaving the red jersey dangerously short of help in the mountains.

3. 37 km to go

   Sivakov leads onto Picón Blanco

   Pavel Sivakov attacks the break and carries over a minute's lead onto the hellish final climb, an 18%-max wall to the ski station of Picón Blanco.

4. 45 km to go

   Dunbar attacks

   With Roglič only tapping out a controlled tempo in red, Eddie Dunbar seizes his chance 5km out, catching and passing Sivakov to lead the queen stage alone.

5. 5At the line

   Dunbar wins the queen stage

   Dunbar emerges from the cloud with his lead intact for a second win of the race, while Roglič rides calmly to the line, defending red without a full team behind him.
