Jonah Koech, the US1500m champion, has been banned from athletics for three years for blood doping, resulting in the stripping of his title. The US Anti-Doping Agency (USADA) identified Koech's doping violation through his athlete biological passport (ABP), which tracks an athlete's blood values over time to detect signs of doping. Koech's ABP showed highly atypical blood values, leading to the ban.
Koech had won the 1500m race at the US Outdoor Championships last year, finishing ahead of notable athletes Ethan Strand and 2024 Olympic gold medallist Cole Hocker, with a meet record time of three minutes 30.17 seconds.
However, his results from July 30,2025, onwards have been disqualified, including the forfeiture of any medals, points, and prizes. This decision comes after Koech accepted the ban for the use of a prohibited substance and/or method.
Koech's blood samples, collected before and after the US Outdoor Championships, revealed abnormal values, prompting the USADA investigation. As a result, Koech has not competed since finishing 13th in the 1500m final at the World Championships in Tokyo last September. Born in Kenya, Koech had competed collegiately in the United States from2015 to 2019 before becoming eligible to represent the country in June 2021.
The three-year ban will significantly impact Koech's athletic career, and his case serves as a reminder of the ongoing efforts to combat doping in athletics. The USADA's use of athlete biological passports has proven effective in detecting doping violations, even in the absence of a positive drug test.
As the athletic community continues to grapple with the issue of doping, Koech's ban will likely have far-reaching consequences for the sport.
