In addition to the standard women's marathon world record, World Athletics also recognizes a second world record for women in the "Women Only" category, meaning that the marathon was run on a course without any male athletes in the competition. The current "Women Only" record of 2:15:50 was set by [[Tigst Assefa]] on April 27, 2025, at the London Marathon in the elite women's race.<ref>{{Cite web |date=2025-04-27 |title=London Marathon: Tigst Assefa sets women's-only world record |url=https://www.bbc.co.uk/sport/athletics/videos/c4gr4y2ek0ro |access-date=2025-04-27 |website=BBC Sport |language=en-GB}}</ref>

==History==
Marathon races were first held in 1896, but the distance was not standardized by the [[World Athletics|International Association of Athletics Federations]] (IAAF, now World Athletics) until 1921.<ref>{{cite web |date=April 25, 2008 |title=The Marathon journey to reach 42.195km |url=http://www.germanroadraces.de/274-1-16409-the-marathon-journey-to-reach-42195km-.html |url-status=live |archive-url=https://web.archive.org/web/20140306080943/http://www.germanroadraces.de/274-1-16409-the-marathon-journey-to-reach-42195km-.html |archive-date=March 6, 2014 |access-date=February 26, 2014 |publisher=european-athletics.org}}</ref><ref>{{Cite book |last=Martin |first=David E. |url=https://archive.org/details/olympicmarathon00mart/page/113 |title=The Olympic Marathon |author2=Roger W.

The actual distance for pre-1921 races frequently varied from the 1921 standard of 42.195&nbsp;km (26 miles 385 yards).

Kipchoge took part in a similar attempt to break the two-hour barrier in Vienna on October 12, 2019, as part of the [[Ineos 1:59 Challenge]].
