Edwin Harold Flack was an Australian athlete and tennis player. Also known as "Teddy", he was Australia's first Olympian, being its only representative in 1896, and the first Olympic champion in the 800 metres and the 1500 metres running events.

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