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 (880 yards), 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.

Runners in this event are often fast enough to compete in the 400 metres or the 4 × 400 metres relay but only Alberto Juantorena and have won major international titles at 400 m and 800 m. If they are so inclined, 400 m runners are usually encouraged to run the 200 metres while 800 m runners are encouraged to run the 1500 metres.

800 meter runners go through a different training plan. As they are planning for the year, they go through different phases. Scott Abbott a track coach of Sacramento State university stated, athlete of the 800 meter trains during the summer by doing base training, cross Country by doing Aerobic development, and winter by doing recovery and transition track workout. Speed work for an 800 athlete could be 100-400m pace run and sprint work. Endurance could simply be 5k/3k pace and high-end Aerobic as Abbott concluded.
