World Athletics 2023 WA vs Hosea Kimeli Kisorio

In December 2023 the Athletics Integrity Unit (AIU), on behalf of World Athletics, reported an anti-doping rule violation against the Kenyan Athlete Hosea Kimeli Kisorio after his sample tested positive for the prohibited substance Erythropoietin (EPO).

Following notification the Athlete initially failed to respond to the communications of the AIU. Ultimately in January 2024 the Athlete timely admitted the violation, waived his right for a hearing and accepted the sanction proposed by the AIU.

The AIU deems that the Athlete failed to demonstrate that the violation was not intentional. Because he had signed and submitted the Admission of Anti-Doping Rule Violations and Acceptance of Consequences Form he received a 1 year reduction from the AIU.

Therefore the AIU decides on 18 January 2024 to impose a 3 year period of ineligibility on the Athlete, starting on the date of the provisional suspension, i.e. on 1 December 2023.
