Service members and civilians stationed at Kandahar Airfield, Afghanistan, start the 24-Hour Run for Charity, April 16, 2011.

A 24-hour run is a form of ultramarathon, in which a competitor runs as far as they can in 24 hours. They are typically held on 1- to 2-mile loops or occasionally 400-meter tracks.

Top runners will often run 200 kilometres (124 mi) or more, depending on conditions, and the best can go beyond 270 kilometres (168 mi). Some participants will have a crew to help them, but others just set up a camp with all the gear and supplies they need near the starting area to access each loop. Often 24-hour events are combined with 6-, 12-, and 48-hour events. 24-hour runs have also been held in relay formats, with runners completing a mile each in succession for 24 hours. Often these events are not internationally sanctioned, and are more for charitable purposes.[1]

The world records for the event on all surfaces are 258.339 km (160.524 miles) for women, set by Patrycja Bereznowska of Poland in 2017,[2] and 303.506 km (188.590 miles) for men, set by Yiannis Kouros in 1997.


The first international championship was held February 3–4, 1990 in Milton Keynes, England.[3] A full continental championship was formed in 1992 as the IAU 24 Hour European Championship.[4]

The IAU 24 Hour World Championship is the pinnacle of competition in the 24-hour run. The first IAU Individual Track Championships were held in San Giovanni Lupatoto, Verona, Italy on 22–23 September 2001.[5]

The German website DUV lists 160 24-hour races that were scheduled for 2012, a figure that has doubled over the last 10 years. The longest running 24-hour race is the Self-Transcendence 24 Hour Race Ottawa, Canada which began in 1981.[6]

A 24-hour race exclusively for youth was started in Hong Kong in 2010, and has continued annually (Running to Stop the Traffik).
