Athletics Integrity Unit v. Imaobong Uko

Nigerian 400m runner Imaobong Uko (a Baylor University athlete and 2021 World U20 champion) was provisionally suspended by the AIU on 7 July 2024 after accumulating three missed "whereabouts" filings within a 12-month period — a violation of the World Athletics Anti-Doping Rules' whereabouts requirements, which obliges elite athletes to keep quarterly-updated location information (home address, training schedule, and a daily 60-minute testing window) on file so out-of-competition testers can locate them. Her third failure reportedly occurred shortly before the 2024 Nigerian Championships, where she still competed and placed third in the 400m.

Uko has publicly stated that she raised, during her AIU hearing, that persistent technical problems with the whereabouts filing platform, combined with what she described as an unresponsive Athletics Federation of Nigeria (AFN), contributed to the missed filings; she named three specific federation officials she says she contacted for help — Mbachi Louis, a Mrs. Onos, and Taldang, the AFN's Assistant Secretary — without receiving timely assistance. She has said that when she raised this directly with federation representatives during the hearing itself, their response was to claim she had incorrectly submitted her information, an accusation she has denied. The AFN publicly rejected her account, stating that whereabouts compliance is the athlete's sole responsibility under the rules (not the federation's), that she had been sent multiple reminders by both the AFN and Nigeria's National Anti-Doping Committee, and that the filing platform is straightforward. At least one unnamed former Nigerian international, quoted in the same reporting, sided publicly with the federation, saying the AIU's process includes step-by-step videos and an FAQ section, and asking how Uko could make the same filing mistake repeatedly: "Nigeria did not fail her, she failed herself." Whatever the merits of that dispute, it did not alter the outcome: the AIU imposed the standard two-year sanction that applies to a third whereabouts failure within 12 months, running from 7 July 2024 to 23 July 2026, with her results nullified from the relevant period.

This case is a useful reminder that "whereabouts failure" sanctions proceed on a strict three-strikes threshold under the Code, independent of an athlete's explanation for any individual missed filing — unlike a positive test, there is no substance-classification or intent analysis to run through, only whether three qualifying failures occurred within the relevant window.
