Middle-distance running events are track races longer than sprints up to 3000 metres. The standard middle distances are the 800 metres, 1500 metres and mile run, although the 3000 metres may also be classified as a middle-distance event. The 880-yard run, or half-mile, was the forebear to the 800 m distance and it has its roots in competitions in the United Kingdom in the 1830s. The 1500 m came about as a result of running three laps of a 500 m track, which was commonplace in continental Europe in the 1900s.
