Marathon world record holder Ruth Chepngetich has been banned for three years by the AIU following her admission to an Anti-Doping Rule Violation regarding the presence and use of Hydrochlorothiazide, a banned diuretic and masking agent in doping. The announcement from the AIU was made public on Thursday morning.

Chepngetich broke the women's marathon world record in 2:09:56 at the 2024 Chicago Marathon. She is the 2019 World Champion and three-time winner of the Chicago Marathon.

The AIU shared that Chepngetich was tested 15 times out of competition and four times in competition in 2024. After she broke the world record, the AIU tested her more as she prepared to race the 2025 London Marathon. Chepngetich struggled in the two races that followed.
