The organisers of the Tour de France are always on the hunt for new climbs, mountain roads or bike paths that have laid undiscovered by the world's biggest bike race. The Col de la Loze, which returns on stage 17, has just been ridden once before; these are the new tests, fresh terrain to break top cyclists on.
Sunday's final climb is different, however. There is nothing new about the Puy de Dôme, it being first used at the Tour in 1952. However, this volcanic climb has been dormant at the Tour since 1988, due to access issues. It is as good as new to the riders at this year's race.
