Athletics Integrity Unit: Kenya's Ruth Chepngetich, the reigning women's marathon world-record holder, has been provisionally suspended after testing positive for a banned substance, the Athletics Integrity Unit (AIU) announced on Thursday.
Chepngetich, 30, tested positive for hydrochlorothiazide (HCTZ), a diuretic and masking agent commonly used to obscure the presence of performance-enhancing drugs. The AIU stated that the sample was collected in March this year, and Chepngetich has “opted for a voluntary provisional suspension while the AIU's investigation was ongoing.”
The news comes less than a year after Chepngetich delivered a historic performance at the 2024 Chicago Marathon, smashing the women's world record by nearly two minutes. She clocked 2:09:56 to become the first woman to run a marathon under 2:10, notching her third win in the Windy City and cementing her place among the sport’s greatest long-distance runners.
