Ruth Chepngetich: AIU and Wada Debate Stripping Marathon World Record

Ruth Chepngetich set the women’s marathon world record in Chicago two years ago, crossing the finish line in 2hr 9min 56sec.

The Doping Ban That Left a Record Intact

Chepngetich tested positive for 20 times the legal limit of hydrochlorothiazide (HCTZ) in her system. Her defence to the Athletics Integrity Unit (AIU) claimed she took her housemaid’s medication after feeling hot and experiencing a rapid resting heartbeat. The AIU dismissed that explanation as hardly credible. Investigators also recovered screenshots on her phone regarding the banned substance testosterone alongside messages discussing programs linked to doping. Chepngetich maintained she never used testosterone and insisted those messages belonged to a group chat. The AIU prosecuted the case, resulting in a three-year ban that runs until 2028. Despite the suspension and the discarded credibility surrounding the performance, her world record remains officially recognized on the books because she passed the mandatory drug test administered immediately after her race in Chicago.

Brett Clothier and the World Anti-Doping Code Defences

Athletics Integrity Unit head Brett Clothier admitted in an interview that the current situation is not satisfactory. The World Anti-Doping Agency (Wada) maintains that stripping past results without evidence or reasonable inference of prior doping would breach multiple legal principles, including human rights and proportionality. Wada pointed out that Lance Armstrong lost his Tour de France titles because he chose not to use procedural avenues to contest his sanctions, making that case a weak precedent for widespread retrospective disqualification. Anti-doping experts interviewed about the dilemma noted that introducing new rules—such as a social contract forcing athletes to forfeit records if caught doping within a year—would require total agreement from global sports federations, governments, and human rights bodies.

AIU Catches 317 Athletes as Shoe Brands Fund Testing

Track and field officials point to aggressive testing numbers to demonstrate active enforcement against cheats. The AIU has caught 317 elite Kenyan athletes since its establishment in 2017, operating on an annual budget of $11.9m (£9m). Major shoe brands are also stepping in to fund independent pre-race screenings. Adidas paid $50,000 for extra testing before Sabastian Sawe set the men’s marathon world record in London. Nike funded similar pre-race screens for Jacob Kiplimo and Brigid Kosgei before Chicago. Meanwhile, athlete representatives are pushing for stricter private contracts. Eric Lilot, an agent representing elite runners, wants to require his athletes to sign agreements forcing them to surrender any prize money still owed if they are ever proven to have intentionally doped.
