Reigning Tour de France champion Chris Froome was forced to run up a portion of Mont Ventoux after Richie Porte's bike collided with a motorcycle in the closing kilometers of Stage 12 of the Tour de France.

Froome started running and then attempted to ride on a replacement bike but caught up to a third bike on his team car. According to the UCI rules, a cyclist can finish a stage on foot as long as they have their bike with them. The two-time champion shook his head as he passed the finish line.

Froome was in the yellow jersey during the race and it appeared that he would lose it after the crash, but a review concluded that he was still on top by 48 seconds. Compatriot Adam Yates is in second.
