Which will be the hardest stage of the 2017 Tour de France?
I was wondering, which do you think will be the hardest stage of the 2017 Tour de France?
Based on current data and predictions, it looks like stage 12, which covers 214.5 kilometers from Pau to Peyragudes in the Pyrenees, will be the toughest stage of this year's race.
