Middle-distance running
Middle-distance running events are track races longer than sprints, ranging from 500 metres up to two miles. 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 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, which were commonplace in continental Europe in the 20th century.
Four-minute mile
A four-minute mile is the completion of a mile run (1.609 km) in four minutes or less. It translates to an average speed of 15 miles per hour (24 km/h). It is a standard of professional middle-distance runners in several cultures.
