The UCI 1.HC and UCI 2.HC were the second tier classification of road cycling races by the UCI, after the UCI World Tour (or its predecessor, the UCI ProTour). They are now replaced by the UCI ProSeries. The races were part of the various UCI Continental Circuits. The 1.HC events were one-day races, whereas the 2.HC events were stage races. 'HC' stands for the French phrase hors catégorie, which means beyond categorization. In 2020, the .HC races were replaced by the UCI ProSeries[1]
