Marathon world record progression
World records in the marathon are ratified by World Athletics, the international governing body for the sport of athletics.
The late Kenyan athlete Kelvin Kiptum set a men's world record time of 2:00:35 on October 8, 2023, at the 2023 Chicago Marathon, a mixed-sex race.
Kenyan athlete Ruth Chepng'etich broke the women's world record with a time of 2:09:56 on October 13, 2024, at the 2024 Chicago Marathon, a mixed-sex race.
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.
