> Races last about two and a half minutes. Each race is six laps (1.5km) in length and cyclists are paced by a motorised bike for three laps with increasing speed from 30kph to 50kph, followed by a three-lap sprint to the finish.
> In the first round, a maximum of 30 riders are organised into five heats. The fastest two from each heat automatically advance to the second round. The remaining 20 are sent to a repechage round, in which they are organised into four five-rider heats, with the top two in each heat advancing.
> A total of 18 riders - 10 from the first round and eight from the repechage - advance to the quarter-finals. The quarter-finals are divided into three heats of six riders each. The top four in each heat advance to the semi-finals with no repechage.
> The semi-finals are divided into two heats of six riders each. The top three in each advance to the final. Gold, silver and bronze are awarded to the top three finishers in that heat. The bottom six from the semi-finals race in a B final to determine places 7-12.
> The riders to watch for: Harrie Lavreysen (Ned), Azizulhasni Awang (Mas), Matthew Richardson (Aus), Ota Kaiya (Jpn), Kevin Santiago Quintero Chavarro (Col), Jack Carlin (Gbr).
