One hour run
The one hour run is an athletics event in which competitors try to cover as much distance as possible within one hour. While officially recognized by the International Association of Athletics Federations as a track event, it is rarely contested apart from occasional world record attempts.
The event has a long history, with first recorded races dating back to the late 17th century.
The first athlete to run more than 20 kilometers in one hour was Emil Zátopek, in September 1951. Zátopek also set the 20,000 meters world record in the same race, and since that time most men's 20,000 m world records were set en route to one hour world records.
The men's world record is, set by Haile Gebrselassie on 27 June 2007, while the women's world record is, set by Dire Tune on 12 June 2008.Women's world record progression
