500mTT

In the track time trial, a track cycling event, cyclists compete individually against the clock to record the fastest time over the specified distance from a standing start.

Track time trial bikes differ from normal track bikes in two major ways; firstly they have disc or 3–5 spoked wheels and secondly they often use aero-bars to allow the rider to adopt a more aerodynamic riding position, for the same reasons as in road individual time trials. The frames are often more streamlined to reduce air resistance.

At the UCI Track World Championships, the distance for senior men is 1,000 metres, hence the event's alternative name, the 'Kilo', short for kilometer. Junior men also race 1000 m. Being such a short, high-intensity event, the kilo is popular with riders who specialise in the sprint. The Kilo time trial was removed from the Olympics programme after 2004 to make way for BMX racing. This led to a number of Kilo riders, most notably Chris Hoy, to begin focusing on other sprint events.

This event is a race against the clock from a standing start over 1,000 m. Most indoor tracks are 250 m in length, so a kilo is usually held over four laps. Other common track lengths are 167 m (six laps), 333 m (three laps) or 400 m (2.5 laps). Riders will keep to the black line at the bottom of the track to ensure they have to cover the least distance over the 1,000 m. Riders usually only get one attempt to set a time, and the winner of the event is simply the rider to post the quickest time.

A fast time at the elite level is around 1 minute 5 seconds.

The world record is 56.303 seconds, set by Francois Pervis in the 2013 Track World Cup at Aguascalientes, Mexico.

The Women's version of the event is held over 500 m. Other than the race distance this is the same as the men's Kilo event, with the fastest rider over the distance declared the winner. This event was also removed from the Olympic programme after 2004 to make way for BMX.

The world record is held by Russian rider Anastasia Voinova; set on 17 October 2015 in Grenchen, Switzerland during the European championships with 32.794 seconds (54.888 km/h).
