The distance-runner faces a potential ban for the use of EPO and furosemide, which are prohibited substances

Brimin Misoi Kipkorir, winner of the 2024 Sydney and 2022/2023 Frankfurt Marathon, has received a provisional suspension for a doping violation.

The Athletics Integrity Unit (AIU) announced Kipkorir was suspended due to the presence of EPO and furosemide, which are prohibited substances. The suspension will remain in effect until his case is resolved.

The AIU added that Kipkorir’s sample came back positive after an out-of-competition test on November 22, 2024.


The Kenyan is a multiple marathon winner and last September secured victory over 26.2 miles in Sydney, recording a course record of 2:06.18.

The 35-year-old set his personal best of 2:04:53 when he won the Frankfurt Marathon in 2023, after having already triumphed at the event a year earlier.

On the current marathon world rankings, he sits in 26th place behind fellow Kenyan Bethwel Kibet.

The last event Kipkorir competed in was the Taipei Marathon in December – after the sample was collected from AIU. He won the event with a time of 2:11:41. Organisers said Kipkorir would receive $67,500 for his victory.
