Thomas Voeckler attacked on top of col du Sappel taking five points which put him level on ninety points with Majka in the KOM standings.

Serge Pauwels passed first atop the col de Pisseloup (cat. 3) and took the two points while Rafal Majka took one point to go back into the KOM lead.
The duo stayed away for the intermediate sprint which Pauwels took but were brought back for the next climb - the Col De La Rochette after 79kms. Pauwels took two more points on that climb with another Majka.
The gap went out to seven minutes so Dylan van Baarle attacked and was joined by Tom Dumoulin and then Astana's Vincenzo Nibali who worked to take their lead back to the peloton to 8.12.

Majka was first over the Grand Colombier with Zakarin in second and Julian Alaphiippe in third. Alaphilippe joined them on the descent along with Pantano.
