1500 metres

The 1500 metres or 1,500-metre run (approximately ¹⁵⁄₁₆ mile) is the foremost middle distance track event in athletics. The distance has been contested at the Summer Olympics since 1896 and the World Championships in Athletics since 1983.

The demands of the race are similar to that of the 800 metres, but with a slightly higher emphasis on aerobic endurance and a slightly lower sprint speed requirement. The 1500 metre race is predominantly aerobic, but anaerobic conditioning is also required.

Each lap run during the world-record race run by Hicham El Guerrouj of Morocco in 1998 in Rome, Italy averaged just under 55 seconds (or under 13.8 seconds per 100 metres). 1,500 metres is three and three-quarter laps around a 400-metre track. During the 1970s and 1980s this race was dominated by British runners, along with an occasional Finn, American, or New Zealander, but through the 1990s a large number of African runners began to take over in being the masters of this race, with runners from Kenya, Morocco, and Algeria winning the Olympic gold medals.

IAAF Diamond League

The IAAF Diamond League is an annual series of track and field meetings held from 2010 onwards, beginning with the 2010 IAAF Diamond League. It was designed to replace the IAAF Golden League, which was held annually since 1998.

While the Golden League was formed to increase the profile of the leading European athletics competitions, the Diamond League's aim is to "enhance the worldwide appeal of athletics by going outside Europe for the first time." In addition to the original Golden League members (except Berlin) and other traditional European meetings, the series includes events in China, Qatar, and the United States.
