From 2005, the Classics have formed part of the UCI ProTour run by the Union Cycliste Internationale. This event series also includes various stage races including the Tour de France, Giro d'Italia, Vuelta a España, Paris-Nice and the Critérium de Dauphiné Libéré, and various non-Classic single day events. The ProTour replaced the UCI Road World Cup series which contained only one-day races.
