Athletics Integrity Unit v. Sarah Chepchirchir

Sarah Chepchirchir, winner of the 2017 Tokyo Marathon, finished second at the Bangsaen42 Chonburi Marathon in Thailand on 5 November 2023 — her comeback race after already serving a four-year period of ineligibility from 6 February 2019 to 5 February 2023, arising from discrepancies in her Athlete Biological Passport. A urine sample collected at that race returned an adverse analytical finding for metabolites of testosterone. She was provisionally suspended on 22 December 2023 as the AIU's hearing process began, with her results disqualified from the date of the race onward. What distinguishes this case procedurally is Chepchirchir's near-total non-engagement with it: she was given until 5 January 2024 to respond to the charge and never did. The AIU then notified her that she had irrevocably waived her right to have the B Sample analysed. She was separately given an exceptional extension to 10 January 2024 to request the laboratory documentation package underlying the finding, or to submit any explanation at all — and again did not respond. She also had a standing offer to admit the violation in exchange for a one-year reduction in whatever sanction followed, with a deadline of 11 February 2024 to do so; she let that deadline pass as well.

Because this was a second violation, and because Chepchirchir made no attempt to establish that it was unintentional or otherwise mitigate her position, the AIU imposed the maximum available sanction: an eight-year period of ineligibility. The ban runs from 22 December 2023 to 21 December 2031, when Chepchirchir would be 47 years old — effectively ending her competitive career.

The case is a useful illustration of how much of the outcome in an anti-doping matter can turn on an athlete's own engagement with the process rather than on contested scientific argument: Chepchirchir's sanction reflects not just the underlying finding but a sequence of missed deadlines and unanswered notices that foreclosed any avenue for a reduced sanction.
