A half marathon is a road running event of 21.0975 kilometres (c. 13 mi 192.5 yd)—half the distance of a marathon. It is common for a half marathon event to be held concurrently with a marathon or a 5K race, using almost the same course with a late start, an early finish, or shortcuts.[circular reference] If finisher medals are awarded, the medal or ribbon may differ from those for the full marathon. The half marathon is also known by its rounded distance: a 21K, a 21.1K, or 13.1 miles.
A half marathon world record is officially recognised by World Athletics. The men's world record time is 56:51, set by Yomif Kejelcha in 2026 in Buenos Aires. Jacob Kiplimo ran 56:42 in Barcelona in 2025, but this mark was not ratified by World Athletics due to his proximity to the lead car. The women's world record, in a mixed-gender race, is 1:02:52, set by Letesenbet Gidey of Ethiopia in October 2021 in Valencia, Spain. The world record for the women's only race is 1:05:15, set by Agnes Jebet Ngetich of Kenya in September 2026.
Participation in half marathons has grown steadily since 2003, partly because it is a challenging distance, but does not require the same level of training that a marathon does. In 2008, Running USA reported that the half marathon was the fastest-growing type of race.
Races close to the official half marathon distance of 21.0975 km (13.1094 mi) have taken place throughout the early 20th century, and athletes have also been timed at the midpoint of full marathons. The 1946 Central American and Caribbean Games in Barranquilla, Colombia featured a road race that is listed at exactly the modern half marathon distance, referred to as the "Carrera Centroamericana y del Caribe: (21 kms. 97,5 metros)". The 1952 South American Championships in Athletics in Buenos Aires, Argentina featured a road race that was 21.097km, referred to as "la media maratón" ('the half marathon') by the Chilean newspaper La Nación.
The earliest half marathon recognised by the ARRS is the 1960 Romford Half Marathon in England, though it was short of the full half marathon distance. The earliest half marathon recognised by World Athletics is the 1965 Feckleton Half Marathon in England. The event grew in popularity, leading to the eventual establishment of the World Athletics Road Running Championships in 1992, originally titled the IAAF World Half Marathon Championships.
