As defined by Union Cycliste Internationale (UCI) rules, the first round of competition used to qualify for the sprint competition is the flying 200 m time trial. In this round each rider completes two to three warm up laps and then completes the final 200 m, which is usually just under a lap. The number of riders that qualify for the sprint rounds depends on the competition; in World Cup competitions, 16 riders will advance and in a world championship, 24 riders will advance.
