The Tour de France is renowned for its grueling climbs, each one presenting a unique challenge to the world's elite cyclists.

As they battle their way up the steep gradients, the categorization of these ascents plays a crucial role in determining the severity and impact on the overall race.

The most challenging climbs are designated as Hors Catégorie (HC), meaning "beyond classification."

These are the behemoths of the Tour, with staggering gradients, extended lengths, and often breath-taking scenery.

Iconic HC climbs like the legendary Col du Tourmalet and the awe-inspiring Mont Ventoux demand the utmost physical and mental fortitude from the riders. - https://francefocusguide.com/blog/how-are-tour-de-france-climbs-categorized/
