Ruth Chepng'etich (often spelled Ruth Chepngetich, born 8 August 1994)[1] is a Kenyan road runner who is the current women's world record holder in the marathon, with a time of 2:09:56 set at the 2024 Chicago Marathon.

The silver medal went to Rose Chelimo of Bahrain with a time of 2:33:46, and bronze went to Namibia's 39-year-old Helalia Johannes, who clocked 2:34:15.

[9][10] Chepng'etich's record has since been broken, and she is currently the sixth fastest woman in history at the distance.

[13][14] On 9 October, Chepng'etich successfully defended her Chicago title at the 2022 Chicago Marathon with a time of 2:14:18, a personal best by almost three minutes, then the second-fastest time in history, and just 14 seconds outside of compatriot Brigid Kosgei's then-world record of 2:14:04.

Chepng'etich ran most of the race well under world record pace as she went out very fast with her first 10 miles clocked at 49:49.
