- Sprint (cycling)
-
The sprint or match sprint is a track cycling event involving between 2 and 4 riders, though they are usually run as a one-on-one match race between opponents who, unlike in the individual pursuit, start next to each other.

Racing style
Depending on the size of the velodrome, this event can be from 600 m to 1000 m. Unlike the sprints in athletics, these events do not usually start with riders sprinting from the starting line and they are not confined to lanes. The early parts of each race will often be highly tactical with riders pedaling slowly, as they carefully jockey for position, often trying to force their opponents up high on the track in an attempt to get their rivals to make the first move. Some even bring their bicycles to a complete stop, balanced upright with both feet still on the pedals (a track stand), in an attempt to make the other rider take the lead. The reason for this apparently strange behavior, as in many track cycling events, is both aerodynamics and tactics.
When racing at high speed, the rider who manages to stay just behind their opponent can draft, expending less effort. By riding behind the 'lead out' rider, the second rider reduces the aerodynamic drag they feel. Just before the finish, the trailing rider pulls out of the slipstream, and using their fresher legs may be able to overtake their opponent before the line. To prevent this, the leading rider may choose to accelerate quickly before the last lap, hoping to catch his opponent off guard and establish a large enough gap to negate the aerodynamic effect or to keep the speed high enough to prevent his opponent from completing a pass.
During the race, the 'lead out' rider may choose to hug the measurement line on the inside of the track, giving him the shortest path around the track, or he may choose to hug the sprinter's line, a red line 85 cm up track, to force his opponent to come higher over the top of him. The sprinter's line defines the sprinter's lane; once the sprint is initiated, riders may not drop into the sprinters lane or cross out of the lane unless they have a clear lead over their opponent.
Rules and Qualifying/Race Format
As defined by 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 2 to 3 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 Championships, 24 riders will advance. The top riders are seeded in the following rounds, meaning the fastest qualifier will face the slowest qualifier and so on. Knock out rounds then proceed, initially on a one race basis and then on a best-of three-race format from the quarter-final stage. Riders defeated in the earlier rounds may get a chance to continue in the competition through the repechage races.
Great Britain currently hold the major titles in this event. Chris Hoy, former World Champion and Olympic Champion, and Victoria Pendleton, World and Olympic Champion, are World Record holders in Individual sprint.
Famous sprinters
Famous track sprinters of the past include Britain's Reg Harris, Australia's Dunc Gray and Sid Patterson, Germany's Michael Hübner and Japan's Koichi Nakano. The former world and current Olympic champion is Chris Hoy, who was recently knighted in the British royal court.
Variants
Keirin
The Keirin is a variant of the sprint in which a higher number (usually 6-8, or 9 in Japan) of sprinters compete in a very different format. Riders are paced in the early laps by (and are required to stay behind) a derny motorcycle, which slowly increases the speed of the race from 25 km/h to about 50km/h. It then leaves the track with about 600-700 m remaining. The first rider across the finish line in the high-speed (sometimes 70 km/h) finish is the winner.
Olympic sprint
Despite its name, the Olympic sprint (also known as the team sprint) is not a conventional match sprint contest but a type of short distance three-man team pursuit held over three laps of a velodrome. Like the (much longer) team pursuit event, two teams race against each other, starting on opposite sides of the track, but at the end of the first lap, the leading rider in each team drops out of the race by riding up the banking leaving the second rider to lead for the second lap; at the end of the second lap, the second rider does the same, leaving the third rider to complete the last lap on his own. In the women's event, teams of two compete over a two-lap distance.
Chariot
The chariot is a short, usually one lap, race. Depending on track size, between 4 and 8 cyclists start from a standing start, and do an all out sprint for one lap. The first rider across the finish line is the winner.
