The 5000 metres (about 3.1 mi or 16,404 ft) is a popular running distance. It is also known as a 5K or 5 km. Colloquially it is called a "five-K". It is one of the track events in the Olympic Games and the World Championships in Athletics. "5000 metres" refers to racing on a track. "5K" usually refers to a roadrace or cross country event. While mainly run as an outdoor event, the 5000 m is sometimes run on an indoor track. Official records are kept for both outdoor and indoor 5000 m track events, but not for 5 km road races.
Much of the distance's popularity is due to the challenge it gives to both amateurs and professionals. It is a distance race that demands a great deal of endurance as well as speed. Strategies also play a key role, and the combination makes it attractive to many.
