This page indexes the Climbs posted on Hors Catégorie, divided into Category 4, Category 3, and Category 2 climbs (there are no Category 1 climbs in the Dublin and Wicklow mountains). As racing fans know, categorisation can be quite arbitrary — at the start of a grand tour, the merest pimple rates Cat 4; deep into the third week, stages can be so packed with mountains that major ascents go entirely unclassified. The categorisation here follows the categorisation of the relevant segment on Strava.
