Which will be the hardest stage of the 2017 Tour de France?
And why do you think that is?
This stage features three tough climbs, including the Col de Menté and the Col de Peyresourde, and finishes with a steep climb to Peyragudes. The terrain is challenging and the distance is long, making it a test of endurance and skill for the riders.
