Kimaiyo Admits Anti-Doping Rule Violation, Gets Two-Year Ban

Kenyan athlete Philemon Kiplimo Kimaiyo has admitted to an anti-doping rule violation after testing positive for the prohibited substance Chlortalidone, earning a two-year ban from competition.

The athlete provided an out-of-competition urine sample in Mwaita, Kenya, on July 19, 2026, during testing conducted under the authority of the World Athletics Athletics Integrity Unit (AIU).

The sample initially had a specific gravity of 1.002, below the required 1.003 threshold for analysis. After providing four further samples, the athlete eventually produced a suitable sample, coded 1780921, which was analysed by a WADA-accredited laboratory in Paris.

The laboratory reported an Adverse Analytical Finding for Chlortalidone on July 29.

Chlortalidone is listed by WADA as a Specified Substance under the S5 category of diuretics and masking agents and is prohibited at all times.

During an AIU interview on August 25, Kimaiyo said he did not know what Chlortalidone was. He explained that about a week before the test, he had taken painkillers belonging to his wife to treat pain after long runs, but could not recall the name or appearance of the medication.

He later supplied photographs of the medication packaging, including a box of Olmecure-CT 40, which contains Olmesartan Medoxomil with Chlortalidone.

Kimaiyo admitted the anti-doping rule violations on September 1 and accepted the consequences.

The AIU said it had no evidence that the violations were intentional, meaning the applicable sanction was two years rather than four.

His suspension began on September 1, 2026, and will run for two years.

The AIU also ordered the disqualification of all his results since July 19, 2026, including the forfeiture of any titles, awards, medals, points, prizes and appearance money earned during that period.

The ban is Kimaiyo’s first anti-doping rule violation.
