Story summary

Olympic and world marathon champion Peres Jepchirchir has been provisionally suspended by the Athletics Integrity Unit (AIU) due to a positive test for EPO, a banned substance. The AIU announced on X that an out-of-competition sample collected in Kenya before her Sydney Marathon victory in August returned an adverse analytical finding. Jepchirchir, who is 33 years old and also a former half marathon world record holder, won the women’s marathon gold at the Tokyo Olympics in 2021 and the world title last year. In most doping cases, athletes are provisionally suspended until their case is resolved with a verdict or dropped. Kenya, known for its world-leading runners, has faced numerous doping allegations over the years, adding scrutiny to its hosting of the 2029 World Track Championships in an African country for the first time.
