Marathon world record holder Ruth Chepngetich has been provisionally suspended by the Athletics Integrity Unit (AIU) after testing positive for the banned substance Hydrochlorothiazide. The test was conducted on March 14th, and revealed a concentration far exceeding the minimum reporting level. The positive test came shortly after Chepngetich’s second-place finish at the Lisbon Half Marathon. Hydrochlorothiazide is a masking agent that can hide the presence of other banned drugs. Chepngetich has the right to appeal the decision. This news comes after she set a new world record at the Chicago Marathon. This isn’t the first time an athlete represented by her agent has tested positive for a banned substance.

**Marathon World Record Holder Ruth Chepngetich Suspended for Doping Violation**

NEW YORK – Ruth Chepngetich, the world record holder in the women’s marathon, has been provisionally suspended by the Athletics Integrity Unit (AIU) for testing positive for Hydrochlorothiazide, a banned masking agent. The positive test occurred on March 14th, with results showing a significantly elevated concentration of the substance in her urine.

The AIU announced the suspension on April 19th, after Chepngetich had already voluntarily suspended herself during the investigation. Hydrochlorothiazide, classified as a diuretic and masking agent, can be used to conceal the presence of other prohibited substances. The positive test was reported shortly after she finished second at the Lisbon Half Marathon.

Chepngetich shattered the marathon world record last year at the Chicago Marathon, becoming the first woman to break both the 2:11 and 2:10 barriers with a time of 2:09:56. Her record-breaking performance had already drawn scrutiny due to the prevalence of doping cases in Kenya, but Chepngetich deflected questions about the legitimacy of her time.

“You know people must talk…so I don’t know,” Chepngetich responded when questioned about her record.

The AIU’s investigation continues, and Chepngetich has the right to a hearing before a Disciplinary Tribunal. She faces a potential two-year ban if found guilty of doping.

This incident also brings renewed attention to Chepngetich’s agent, Federico Rosa, whose other represented athletes have previously faced doping charges and bans, including Rita Jeptoo, Jemima Sumgong, Lawrence Cherono, Sarah Chepchirchir, Titus Ekiru, and Sheila Chelangat.
