WOMEN’S marathon world record holder Ruth Chepngetich has been banned for three years by World Athletics after she admitted to breaking anti-doping rules.
Chepngetich, a Kenyan, was provisionally suspended in July following a positive test for Hydrochlorothiazide (HCTZ) — a banned diuretic used commonly as a masking agent — in March.
However, Chepngetich’s achievements which pre-date that sample, including her world record time of two hours, nine minutes and 56 seconds in Chicago in October 2024, will remain valid.
The Athletics Integrity Unit (AIU) had sought a four-year ban but the 31-year-old’s punishment was reduced to three years because she admitted to the violations.
However, the AIU said it will continue to investigate evidence from Chepngetich’s phone which it found indicate “a reasonable suspicion that her positive test may have been intentional” – including messages dating back to 2022.
Brett Clothier, head of the AIU, said: “The case regarding the positive test for HCTZ has been resolved, but the AIU will continue to investigate the suspicious material recovered from Chepngetich’s phone to determine if any other violations have occurred.”
When interviewed in April by the AIU, Chepngetich, the first woman to run a marathon in under 2 hours 10 minutes, could not provide an explanation for the positive test.
While HCTZ has a minimum reporting level of 20 nanograms per millilitre (ng/mL) in urine, Chepngetich’s sample showed an estimated concentration of 3,800 ng/mL.
Chepngetich changed her explanation on July 31, claiming that she had taken her housemaid’s medication — marked as being HCTZ — after becoming ill two days before the positive test.
The AIU said it had “serious reservations about the credibility of the new version of events” and, in the context of the sport’s anti-doping rules, such “recklessness” is considered “indirect intent, for which an increased four-year sanction applies”.
An automatic one-year reduction was applied after Chepngetich admitted the anti-doping rule violations within the 20 days required.
The three-year ban began on April 19 — when Chepngetich accepted a voluntary provisional suspension — with the athlete’s results, awards, titles, appearance and prize money since March 14 forfeited.
AIU chair David Howman said the case underlined that “nobody is above the rules”.
“While disappointing for those who put their trust in this athlete, this is how the system is supposed to work,” Howman said.
“The road-running industry should be commended for collectively funding anti-doping efforts capable of uncovering doping violations committed by elite athletes in their events.”
