The Athletics Integrity Unit (AIU) has suspended Kenyan Albert Korir for doping.
The 2:06:57 marathon runner who won the 2025 Ottawa Marathon (2:08:22) tested positive for CERA, a red blood cell booster and a prohibited substance on the World Anti-Doping Agency list.
Korir is a five-time top-three finisher at the New York Marathon.

Canadian Rory Linkletter finished second to Korir in 2:08:31. His personal best is 2:06:49 from Chicago this year.
Korir’s suspension is provisional and appealable. Once the suspension is a ban, it is expected that the Ottawa Marathon will award Linletter the win.
Kenya continues to have a major doping problem. Currently, there are well over 100 athletes suspended for doping-related offences from the small East African nation. Nearly 500 have been suspended since 2016. Doping at these levels would be cause for federal government intervention in most countries.
