800 metres

The 800 metres, or 800 meters (US spelling), is a common track running event. It is the shortest common middle-distance running event. The 800 metres is run over two laps of the track (400 metre track) and has been an Olympic event since the first games in 1896. During indoor track season the event is usually run on a 200-metre track, therefore requiring four laps.

The event was derived from the imperial measurement of a half a mile, a traditional English racing distance. Imperial racing distances were common in the United States. American high schools (in the name of the NFHS) were the last to convert to metric distances in 1980, following the NCAA's conversion in 1976. Countries associated to the English system converted to metric distances after the 1966 Commonwealth Games. 800 m is 4.67 m less than half a mile.

The event combines aerobic endurance with anaerobic conditioning and sprint speed. Both the aerobic and anaerobic systems are being taxed to a high extent, thus the 800 metre athlete is required to combine training between both systems.

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.
