You are wrong.

Also the Hors categorie...tougher than cat 1
Hors catégorie is a French term used in cycle races (most notably, the Tour de France) to designate a climb that is "beyond categorization", an incredibly tough climb. Most climbs in cycling are designated from Category 1 (hardest) to Category 4 (easiest), based on both steepness and length. A climb that is harder than Category 1 is designated as hors catégorie. The term was originally used for those mountain roads where cars were not expected to be able to pass.
