At the UCI Track World Championships, the distance for senior men is 1000 m, hence the event's alternative name, the 'Kilo', short for kilometre.
This event is a race against the clock from a standing start over 1000 m. Most indoor tracks are 250 m in length, so a kilo is usually held over four laps.
The world record is held by Russian rider Anastasia Voynova; set on 17 October 2015 in Grenchen, Switzerland during the European championships with 32.794 seconds (54.888 km/h).
They will ride around the very top of the track as they near the start line, then drop down to the bottom to gain as much speed as possible from rolling down the steep inclined banking.
The world record of 9.100 seconds was set by Nicholas Paul of Trinidad and Tobago at the Elite Pan American Track Cycling Championships in Cochabamba, Bolivia on September 6, 2019.
