Froome won stage fifteen, which finished on Mont Ventoux. Kennaugh and Porte dropped all of the leading contenders except Contador on the early part of the climb, before Froome surged clear of Contador with remaining and caught Quintana, who had attacked earlier in the climb. The pair worked together to put time into their rivals, before Froome dropped Quintana with remaining and soloed to the finish. This gave Froome a lead of four minutes and fourteen seconds over Mollema in second place, with Contador a further eleven seconds back. Froome also regained the lead in the mountains classification. He won the stage seventeen time trial, finishing the course from Embrun to Chorges in 51 minutes 33 seconds, with Contador coming in nine seconds behind him, in second place. Froome defended his lead during the Alpine stages, extending his overall lead as Mollema and Contador dropped back.
