800 metres

The 800 metres is a track race run over two laps of a standard 400-metre outdoor track. It combines sustained speed with tactical positioning and endurance.

800 metres tactics: The positioning and pacing strategies used to compete in an 800-metre race. Explains when runners accelerate, pass, and protect position across the two laps.
David Rudisha: A Kenyan middle-distance runner who won Olympic 800-metre gold in 2012 and 2016. His 2012 Olympic final set the world record in a race led from the front.

Athletics at the Summer Olympics: The track-and-field competitions held as part of the Summer Olympic Games. The Olympics established the 800 metres as a prominent international championship event.
Interval training: A training method that alternates periods of hard exercise with recovery periods. It develops the speed and recovery needed for repeated high-intensity running.
Pacing: The distribution of effort and speed across a race or other endurance effort. An even or varied pace changes the physiological cost of the 800 metres.
Jarmila Kratochvílová: A Czech former runner who set the women's 800-metre world record in 1983. Her long-standing record anchors debate about performance and anti-doping history.
1500 metres: A track race covering three and three-quarter laps of a standard 400-metre outdoor track. It places greater emphasis on sustained aerobic capacity than the 800 metres.
Women's 800 metres at the Olympics: The Olympic women's 800-metre event, first held at the 1928 Summer Games and restored in 1960. Its early removal and later return shaped the event's history in women's athletics.
VO₂ max: The highest rate at which an individual's body can take up and use oxygen during exercise. It measures an aerobic capacity relevant to sustaining fast 800-metre running.
