They build up an advantage of 7.15 as the rain started to come down as they went through the feedzone at Mornas at which point Kris Broeckmans retired.
Onto the Col de Lescou which has gradients of 4.7% and the duo were still around six minutes clear.

The peloton started to put the hammer down and the gap dropped to 3.27 with twenty kilometres to go, meaning that Keizer was no longer the virtual leader on the road.

With the gap down to thirty seconds, Gautier got up to Van der Sande as Keizer broke away and went over the climb. They were joined by Chad Haga and Tim Wellens of Lotto Soudal who cauught up to Keizer with 8kms left.
The attacks from the peloton continued and Rohan Dennis had to put in one burst of speed of keep others in check.
A small group including Nibali was pulled everyone back and Tony Martin joined Oss and Tammerink before Adam Yates brought them all back again with two kilometres left.
