Despite numerous riders, including Tour de France leader Chris Froome, begging spectators not to run alongside the riders as they climb mountains, some fans still feel the need to do so.
Froome courted controversy after elbowing a Colombian fan out of the way on stage eight and then raucous fans caused the carnage on Mont Ventoux when Froome was forced to run up the hill.
But on stage 15, one wannabe Usain Bolt was apprehended by one of his fellow spectators as he ran alongside Julian Alaphilippe (Etixx-Quick Step) on the Grand Colombier climb.
The topless running man was hauled to the side of the road by a chap wearing an Ag2r La Mondiale top and looked a little startled to be stopped in his tracks.
With plenty of mountain stages still to come we're sure to see more people trying to run alongside the riders, but if you're in doubt about which kind of spectator to be, be the guy in the Ag2r top.
