Alpe d’Huez is a legendary climb, world-renown by cyclists. A relentless 8.5 miles with 21 hairpin bends and 8.1 percent gradient, it’s been a stage that can make or break the Tour de France for riders. But, it’s not included in every Tour. This epic climb only comes once in awhile. And, what’s important about it is the decisiveness of Alpe d’Huez in determining the overall leaders. Historically, the winner of the entire Tour has often been in the yellow leader jersey following the Alpe d'Huez stage. Meaning, how riders compete on this one stage is critical in determining the outcome of the entire race.
