Kenyan long-distance runner and world record-holder Ruth Chepngetich has been provisionally suspended after testing positive for a banned substance, the Athletics Integrity Unit (AIU) announced on Saturday.
Chepngetich, 30, tested positive for hydrochlorothiazide, a diuretic listed on the World Anti-Doping Agency’s (WADA) prohibited substances list due to its potential use as a masking agent for performance-enhancing drugs. The test was conducted in March, and she voluntarily accepted a provisional suspension in April, pending the outcome of a full investigation.
One of the most prominent figures in women’s marathon running, Chepngetich made headlines in 2024 when she shattered the women’s marathon world record at the Chicago Marathon, finishing in 2:09:56. The historic performance marked the first time a female athlete had completed the marathon in under two hours and 10 minutes.
The AIU stated that its investigation has entered a decisive stage, and Chepngetich now faces possible disciplinary proceedings. If found guilty, she could face a ban of up to two years from competition.
Hydrochlorothiazide is commonly used for medical conditions such as hypertension, but in the context of sports, it is strictly prohibited due to its ability to dilute urine and potentially conceal the presence of other banned substances.
Chepngetich’s suspension comes amid increased scrutiny of Kenyan athletes following a string of doping violations in recent years. Kenyan authorities, in coordination with international anti-doping agencies, have intensified efforts to clean up the sport and safeguard the country’s storied legacy in distance running.
The disciplinary hearing is expected to take place in the coming months, where Chepngetich will have the opportunity to present her defense.
