Stage 18

The road

How it was won

1. 113 km to go

   Four flat kilometres, then Domancy

   The first mountain time trial at the Tour since Alpe d'Huez in 2004 opens with a gentle run out of Sallanches before pitching up the Côte de Domancy — the climb that made Hinault a world champion.

2. 29 km to go

   Porte's road-bike gamble

   Richie Porte has chosen a road bike over a time trial machine and it looks inspired: 11:33 at the top of Domancy, nine seconds up on Dumoulin, and the first 'wow' of the afternoon.

3. 34 km to go

   Froome finds his rhythm

   Twenty-two seconds down on Dumoulin at the first check, Froome is only ten adrift at the second. Porte's speed has drained away; Quintana is already more than a minute back and struggling.

4. 4At the line

   Froome wins the mountain TT

   Off the technical descent into Megève the yellow jersey stops the clock at 30:43, 21 seconds faster than Dumoulin and 33 up on Aru. A third stage win, and the Tour is now a formality.
