Kenyan distance runner Caren Chelagat has been handed a four-year ban from athletics after the Athletics Integrity Unit (AIU) found her guilty of two anti-doping rule violations involving the prohibited substance norandrosterone.
The 31-year-old road runner received the sanction after an in-competition urine sample she provided at the Durban International Marathon in South Africa on May 3, 2026, returned an adverse analytical finding for exogenous 19-norandrosterone.
The AIU decision, published on September 4, 2026, imposed a four-year period of ineligibility beginning July 17, 2026. The ruling also disqualifies Chelagat’s competition results from May 3, 2026, meaning she loses any titles, medals, prize money and appearance fees associated with those results.
The AIU found Chelagat responsible for two Anti-Doping Rule Violations under the World Athletics Anti-Doping Rules.
The first violation falls under Rule 2.1, which concerns the presence of a prohibited substance, its metabolites or markers in an athlete’s sample.
The second falls under Rule 2.2, which covers the use or attempted use of a prohibited substance or prohibited method.
The substance detected in Chelagat’s sample was exogenous 19-norandrosterone, a metabolite associated with nandrolone, an anabolic androgenic steroid.
The substance appears on the World Anti-Doping Agency’s Prohibited List under the S1.1 Anabolic Androgenic Steroids category and is prohibited at all times.
The AIU therefore determined that Chelagat had committed anti-doping violations based on the laboratory finding and the applicable strict-liability rules.
Chelagat did not admit to intentionally using a prohibited substance.
During the proceedings, she suggested that the adverse finding could have resulted from medical treatment she received at a health facility several days before the Durban marathon.
However, the AIU said she did not provide sufficient supporting medical documentation to establish that the prohibited substance entered her system unintentionally.
Under anti-doping rules, athletes are responsible for substances detected in their samples. An athlete can avoid or reduce a sanction by establishing, under the applicable rules, that the violation was not intentional or that another recognised mitigating circumstance applies.
In Chelagat’s case, the AIU concluded that she had not demonstrated that the violations were unintentional. As a result, she received the standard four-year period of ineligibility applicable to the violations.
The doping case directly affects Chelagat’s performance at the Durban International Marathon.
She finished fifth in the women’s race in 2:40:40, a performance that represented a marathon personal best.
However, because the sample that triggered the anti-doping case came from that competition, the AIU has now disqualified her result.
The disqualification applies to her results from May 3, 2026, onward.
This means Chelagat will forfeit the benefits attached to the affected results, including any medals, titles, ranking points, prize money and appearance fees.
Her 2:40:40 performance therefore no longer stands as a valid competitive result.
The AIU imposed the four-year sanction effective July 17, 2026. The period of ineligibility means Chelagat cannot participate in competitions or activities covered by the anti-doping rules during the ban.
The ruling also places her competitive career on hold until the period of ineligibility expires, unless the sanction is successfully changed through an appeal or another recognised legal process.
The AIU decision noted that Chelagat did not qualify for a reduction based on a voluntary admission of the violation. She had maintained her position that she did not knowingly commit the anti-doping violations.
Chelagat retains the right to challenge the decision through the applicable appeal process.
The AIU decision also identifies the relevant parties, including the World Anti-Doping Agency (WADA) and the Anti-Doping Agency of Kenya (ADAK), as parties that may have appeal rights under the rules.
Any appeal would go before the Court of Arbitration for Sport (CAS) in Lausanne, Switzerland, in accordance with the applicable procedures.
Until an appeal changes the ruling, the four-year ban and disqualification of her affected results remain in force.
Chelagat has competed primarily in road races, including long-distance events. Her career has included competition in the 10-kilometre, half-marathon and marathon distances.
Before her Durban result was disqualified, her 2:40:40 marathon performance represented her fastest recorded marathon time. She also recorded a 35:48 personal best over 10 kilometres, achieved in 2022.
However, Chelagat has not held a Kenyan, African or world record.
