The 10,000 metres or the 10,000-metre run is a common long-distance track running event. The event is part of the athletics programme at the Olympic Games and the World Athletics Championships, and is common at championship-level events. The race consists of 25 laps around an Olympic-sized 400 m track. It is less commonly held at track and field meetings due to its duration. The 10,000-metre track race is usually distinguished from its road running counterpart, the 10K run, by referring to the distance in metres rather than kilometres.
