Story summary

Ruth Chepngetich, the Kenyan marathon world record holder, received a three-year ban for anti-doping violations involving hydrochlorothiazide (HCTZ).
A urine sample collected on March 14, 2025, revealed a concentration of 3,800 ng/mL, significantly above the World Anti-Doping Agency's limit of 20 ng/mL.
Although Chepngetich initially denied wrongdoing, she later claimed to have unknowingly ingested her housemaid's medication while ill.
The Athletics Integrity Unit (AIU) found evidence of potential intentional doping, including suspicious messages from her phone.
Chepngetich's record time of 2:09:56 from the 2024 Chicago Marathon will remain valid as the AIU continues its investigation.

History

Historical Context

The Anti-Doping Act of 1990 laid the groundwork for regulating performance-enhancing drugs in sports, following earlier efforts like the International Olympic Committee's first drug tests in 1968. The establishment of the World Anti-Doping Agency (WADA) in 1999 aimed to unify anti-doping standards globally. Ruth Chepngetich's recent three-year ban for exceeding the hydrochlorothiazide limit illustrates ongoing enforcement challenges in maintaining fair competition.
