Athletics Integrity Unit v. Brian Kipsang

Note on procedural posture. As with the other AIU matters in this library, Kipsang did not contest the finding or request a hearing; he admitted the violation and accepted the proposed consequences. There is accordingly no adversarial CAS-style record of arguments raised and countered — the analysis below instead traces how the AIU actually arrived at the sanction, since that involved a distinct classification question (Specified vs Non-Specified Substance) worth setting out precisely.

Facts. Kipsang, a 30-year-old Kenyan marathon runner with a personal best of 2:07:56 set in Rome the previous year, provided an In-Competition urine sample on 16 March 2025, hours before the Rome Marathon, where he finished second in 2:07:58 — behind fellow Kenyan Robert Ngeno and ahead of compatriot Joshua Kogo, a Kenyan sweep of the podium. His result from the 2024 TCS Toronto Waterfront Marathon (fifth place, 2:08:38, run the previous October) is unaffected and stands, since disqualification under this decision runs only from 16 March 2025 onward. On 1 April 2025, the WADA-accredited laboratory in Rome reported an Adverse Analytical Finding for Triamcinolone acetonide, a corticosteroid used therapeutically to reduce inflammation. The AIU notified Kipsang of the finding on 9 April 2025. He did not request analysis of the B Sample by the 9 April deadline and was accordingly deemed to have irrevocably waived that right; he then had until 25 April 2025 to respond on the remaining matters. On 1 May 2025, the AIU received a signed Admission of Anti-Doping Rule Violations and Acceptance of Consequences form. Kipsang held no Therapeutic Use Exemption for the substance.

Why the sanction band differs from the EPO and Trimetazidine cases above. Triamcinolone acetonide is classified as a Specified Substance under the WADA Prohibited List (category S9, Glucocorticoids), in contrast to the Non-Specified Substances at issue in the Korir and Solomon matters. For a Specified Substance, the standard four-year sanction only applies where the anti-doping organisation establishes that the violation was intentional; absent such a finding, the standard sanction is two years. The AIU did not establish that Kipsang's violation was intentional, so the two-year band applied directly — there was no separate one-year "admission credit" to calculate here, since Rule 10.8.1's admission-credit mechanism only operates on an asserted period of four years or more.

Outcome. The AIU imposed a two-year period of ineligibility running from 1 May 2025 to 1 May 2027, and disqualified all of Kipsang's results, medals, ranking points, and appearance money from 16 March 2025 onward. The decision was publicly announced on 5–6 May 2025 and is final at the AIU level as against the athlete; WADA and Kenyan anti-doping authorities retain an independent right of appeal to the Court of Arbitration for Sport.

Placed alongside Korir and Solomon, this case is best read as a comparison point on substance classification rather than on admission mechanics: three broadly similar-looking sanction outcomes (five, three, and two years respectively) rest on materially different legal starting points — Non-Specified with aggravating factors, Non-Specified without them, and Specified without proven intent. Kipsang's suspension was one of 25 athletes reported sanctioned for doping violations in April 2025 alone, a figure contemporaneous reporting described as broadly consistent with the pace of AIU sanctions since the unit's creation.
