The next counting event is the Tour of Flanders on Sunday, April 6.
The UCI’s WorldTour Ranking is compiled using a points system, with points awarded for one-day race, tour stage and stage race overall finishing positions for events in the UCI’s WorldTour.
The amount of points awarded depends on the ranking of the event. For example, winning the Tour de France overall gives a rider twice as many points as winning the Eneco Tour overall.
