Sprinting is running over a short distance at the top-most speed of the body in a limited period of time. It is used in many sports that incorporate running, typically as a way of quickly reaching a target or goal, or avoiding or catching an opponent. Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the depletion of phosphocreatine stores in muscles, and perhaps secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis.
The 800 metres, or meters, is a common track running event. It is the shortest commonly run middle-distance running event. The 800 metres is run over two laps of an outdoor (400-metre) track and has been an Olympic event since the first modern games in 1896. During the winter track season the event is usually run by completing four laps of an indoor 200-metre track.
The 400 metres, or 400-meter dash, is a sprint event in track and field competitions. It has been featured in the athletics programme at the Summer Olympics since 1896 for men and since 1964 for women. On a standard outdoor running track, it is one lap around the track. Runners start in staggered positions and race in separate lanes for the entire course. In many countries, athletes previously competed in the 440-yard dash (402.336 m)—which is a quarter of a mile and was referred to as the "quarter-mile"—instead of the 400 m (437.445 yards), though this distance is now obsolete.
The 200 metres, or 200-meter dash, is a sprint running event. On an outdoor 400 metre racetrack, the race begins on the curve and ends on the home straight, so a combination of techniques is needed to successfully run the race. A slightly shorter race, called the stadion and run on a straight track, was the first recorded event at the ancient Olympic Games. The 200 m places more emphasis on speed endurance than shorter sprint distances as athletes predominantly rely on anaerobic energy system during the 200 m sprint. Similarly to other sprint distances, the 200 m begins from the starting blocks. When the sprinters adopt the 'set' position in the blocks they are able to adopt a more efficient starting posture and isometrically preload their muscles. This enables them to stride forwards more powerfully when the race begins and start faster.
The 4 × 100 metres relay or sprint relay is an athletics track event run in lanes over one lap of the track with four runners completing 100 metres each. The first runners must begin in the same stagger as for the individual 400 m race. Each runner carries a relay baton. Before 2018, the baton had to be passed within a 20 m changeover box, preceded by a 10-metre acceleration zone. With a rule change effective November 1, 2017, that zone was modified to include the acceleration zone as part of the passing zone, making the entire zone 30 metres in length. The outgoing runner cannot touch the baton until it has entered the zone, and the incoming runner cannot touch it after it has left the zone. The zone is usually marked in yellow, frequently using lines, triangles or chevrons. While the rule book specifies the exact positioning of the marks, the colours and style are only "recommended". While most legacy tracks will still have the older markings, the rule change still uses existing marks. Not all governing body jurisdictions have adopted the rule change.
60 metres hurdles is a distance in hurdling which is generally run in indoor competitions. It is equivalent with the first 5 hurdles of a standard outdoor hurdle race. The current women's and men's world records are 7.65 seconds and 7.27 seconds, respectively.
The 5000 metres or 5000-metre run is a common long-distance running event in track and field, approximately equivalent to 3 miles 188 yards or 16,404 feet 2 inches. It is one of the track events in the Olympic Games and the World Championships in Athletics, run over 12+1⁄2 laps of a standard track. The same distance in road running is called a 5K run; referring to the distance in metres rather than kilometres serves to disambiguate the two events. The 5000 m has been present on the Olympic programme since 1912 for men and since 1996 for women. Prior to 1996, women had competed in an Olympic 3000 metres race since 1984. The 5000 m has been held at each of the World Championships in Athletics in men's competition and since 1995 in women's.
The 3000 metres or 3000-metre run is a track running event, also commonly known as the "3K" or "3K run", where 7.5 laps are run around an outdoor 400 m track, or 15 laps around a 200 m indoor track.
The 3000 metres steeplechase or 3000-meter steeplechase is the most common distance for the steeplechase in track and field. It is an obstacle race over the distance of the 3000 metres, which derives its name from the horse racing steeplechase.
The 4 × 800 metres relay is an athletics track event in which teams consist of four runners who each complete 800 metres or 2 laps on a standard 400 metre track.
The 10-second barrier is the physical and psychological barrier of completing the 100 metres sprint in under ten seconds. The achievement is traditionally regarded as the hallmark of a world-class male sprinter. Its significance has become less important since the late 1990s, as an increasing number of runners have surpassed the ten seconds mark. The current men's world record holder is Usain Bolt, who ran a 9.58 at the 2009 IAAF World Championship competition.
The World Athletics Relays, known as the IAAF World Relays until 2019, is an international biennial track and field sporting event held by World Athletics where teams from around the world compete in relay races, some of which are not part of the standard Olympic programme. The first three editions were set to take place in Nassau, Bahamas at the Thomas Robinson Stadium in 2014, 2015 and 2017. Originally intended as an annual event, it was later decided to happen every odd year, the same as the World Athletics Championships for which it serves as a qualification stage.
Alessandro Sibilio is an Italian sprinter and hurdler, who competes in the 400 metres hurdles and 400 metres. He won a gold medal at the 2018 IAAF World U20 Championships. He competed at the 2020 Summer Olympics, in 400 m hurdles.
Alice Mangione is an Italian sprinter, specialising in the 400 metres. She competed at the 2020 Summer Olympics, in 4 × 400 m relay and 4 × 400 m mixed relay.
The men's 4 × 400 metres relay at the 2021 World Athletics Relays was held at Silesian Stadium on 1 and 2 May.
The Borlée family is a sporting family consisting of many athletes, one of whom, the progenitor Jacques, became a coach in the world of athletics.
Trevor Stewart is an American Olympic athlete. He won a gold medal in the men's 4x400 metres relay and a bronze medal in the mixed 4x400 metres relay at the 2020 Summer Olympics.
The men's 4 × 400 metres relay at the 2021 World Athletics U20 Championships was held at the Kasarani Stadium on 21 and 22 August.
