800 metres - choose a jigsaw puzzle to solve

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.
