UCI Cycling World Championships

The UCI Cycling World Championships is the multi-discipline world championship event for cycle sports, organised by its governing body the Union Cycliste Internationale (UCI). It brings together the individual cycling disciplines, which hold separate UCI World Championships events, to be held as part of one event every 4 years; these disciplines will also continue to hold separate annual world championship events outside of the planned quadrennial editions.
