And as stage 18 is underway, cyclists are making their final push.
Polish cyclist Pawel Poljanski shared a photo that some might find a little freaky of his legs on social media with the caption, "After 16 stages, I think my legs look a little tired."
His very veiny and sunburnt legs show the physical effects of the Tour de France.
Chris Froome, the defending champion also shared his legs ahead of a competition back in 2014.
Tour de France is a 111.5 mile ride up to the Col d'Izoard.
Froome currently holds a 27-second lead over two others ahead of stage 18.
