Jonah Koech Faces Three-Year Ban for Blood Doping
Jonah Koech, an American middle-distance runner, has been banned from athletics for three years due to blood doping violations.
The US Anti-Doping Agency (USADA) announced that Koech's doping was detected through abnormal blood values in his athlete biological passport, which monitors blood parameters over time. As a result, he has been disqualified from all competitive results since July 30, 2025, including the forfeiture of medals and prizes.
Koech, who won the men's 1500m at the US Outdoor Championships last year, accepted the ban for using a prohibited substance or method. He has not competed since finishing 13th in the 1500m final at the World Championships in Tokyo last September.
