Athletics is a group of sporting events that involves competitive running, jumping, throwing, and walking. The most common types of athletics competitions are track and field, road running, cross country running, and racewalking.
The hammer throw is one of the four throwing events in regular track and field competitions, along with the discus throw, shot put and javelin.
World Athletics is the international governing body for the sport of athletics, covering track and field, cross country running, road running, racewalking, mountain running, and ultra running. Included in its charge are the standardization of rules and regulations for the sports, recognition and management of world records, and the organisation and sanctioning of athletics competitions, including the World Athletics Championships. The organisation's president is Sebastian Coe of the United Kingdom, who was elected in 2015 and re-elected unopposed in 2019 for a further four years.
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 World Athletics Championships are a biennial athletics competition organized by World Athletics.
The 400 metres hurdles is a track and field hurdling event. The event has been on the Olympic athletics programme since 1900 for men and since 1984 for women.
The 400 metres, or 400-metre dash, is a sprinting 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.
Athletics has been contested at every Summer Olympics since the birth of the modern Olympic movement at the 1896 Summer Olympics. The athletics program traces its earliest roots to events used in the ancient Greek Olympics. The modern program includes track and field events, road running events, and racewalking events. Cross country running was also on the program in earlier editions but it was dropped after the 1924 Summer Olympics.
The 5000 meters or 5000-meter 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 meters 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 50 kilometre race walk is an Olympic athletics event. The racewalking event is competed as a road race. Athletes must always keep in contact with the ground and the supporting leg must remain straight until the raised leg passes it. Fifty kilometres is approximately 31 miles.
The 2017 IAAF World Championships, the sixteenth edition of the IAAF World Championships, were held from 4 to 13 August at London Stadium in London, UK. London was officially awarded the championships on 11 November 2011.
Karsten Warholm is a Norwegian athlete and Olympic champion who competes in the sprints and hurdles. In July 2021, he broke the 29-year-old world record in 400 metres hurdles. The following month at the 2020 Summer Olympics, he won the gold medal in the 400 metres hurdles with a time of 45.94 seconds, breaking his own world record by over three-quarters of a second. The race has been described by many as one of the greatest in Olympic history due to the records set and the high class field of competitors. Warholm has also won gold in the event at the World Championships in 2017 and 2019, as well as the 2018 European Championships.
Athletics at the 2020 Summer Olympics were held during the last ten days of the Games. They were due to be held from 31 July – 8 August 2020, at the Olympic Stadium in Tokyo, Japan. Due to the COVID-19 pandemic, the games were postponed to 2021, with the track and field events set for 30 July – 8 August 2021. The sport of athletics at these Games was split into three distinct sets of events: track and field events, remaining in Tokyo, and road running events and racewalking events, moved to Sapporo. A total of 48 events were held, one more than in 2016, with the addition of a mixed relay event.
The sports under the umbrella of athletics, particularly track and field, use a variety of statistics. In order to report that information efficiently, numerous abbreviations have grown to be common in the sport. Starting in 1948 by Bert Nelson and Cordner Nelson, Track & Field News became the leader in creating and defining abbreviations in this field. These abbreviations have also been adopted by, among others, World Athletics; the world governing body, various domestic governing bodies, the Association of Track and Field Statisticians, the Association of Road Racing Statisticians, the Associated Press, and the individual media outlets who receive their reports. These abbreviations also appear in Wikipedia.
The 2019 IAAF World Athletics Championships was the seventeenth edition of the biennial, global athletics competition organised by the International Association of Athletics Federations (IAAF), since renamed World Athletics. It was held between 27 September and 6 October 2019 in Doha, Qatar, at the renovated multi-purpose Khalifa International Stadium, but reduced to 21,000 available seats. 1,772 athletes from 206 teams competed in 49 athletics events over the ten-day competition, comprising 24 events each for men and women, plus a mixed relay. There were 43 track and field events, 4 racewalking events, and 2 marathon road running events. The racewalking and marathon events were held in Doha Corniche.
