Cycling shoes are not meant for running. In fact, they're actually pretty difficult to run in, thanks to the big hunk of metal that connects the sole of the shoe to the pedal.

So keep that in mind when you watch British cyclist Chris Froome do this:

Late in the twelfth stage of the Tour de France, Froome was riding in the lead up Mont Ventoux on Thursday when fellow cyclist Richie Porte crashed into a motorcycle, knocking Froome off his bike amid a crowded scrum of spectators, cameras, and other cyclists.

So he put all that endurance training to use, and started running.

Eventually, his team scrounged up a new bike and set him back on the road, allowing him to finish on two wheels.

For his part, though, Froome managed to hold on to the famous yellow jersey. After a jury review, the ASO, which manages the Tour, cited the “exceptional situation” and ruled that he likely would have finished quickly enough in the stage to hold onto the leader's jersey.

Froome was pleased, even if his feet likely weren't.
