Middle-distance running events are track races longer than sprints, ranging from 500 metres up to two miles (3218.688 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.[1] The 1500 m came about as a result of running 3+3⁄4 laps of a 400 m outdoor track or 7+1⁄2 laps of a 200 m indoor track,[2] which were commonplace in continental Europe in the 20th century.[3]
Middle-distance running is unique in that it typically requires attributes found in both sprinters and long-distance runners, including combinations of both footspeed and aerobic endurance. Middle-distance racing is commonly reported to be an extremely intense physical experience, requiring large amounts of anaerobic exertion from the body.
