Brimin Kipkorir (born 25 May 1989) is a Kenyan long-distance runner specializing in marathon events. He has won several major international marathons, including the Frankfurt Marathon and Sydney Marathon, and set multiple course records. However, he is currently under provisional suspension due to a doping violation.
Kipkorir was born in Kapkitony, Keiyo South, Kenya. Before fully committing to athletics, he worked as a farmer in his village.
Kipkorir's marathon career has been marked by consistent performances and major victories:
In February 2025, the Athletics Integrity Unit (AIU) provisionally suspended Kipkorir after he tested positive for EPO and furosemide. The sample was collected during an out-of-competition test on 22 November 2024.
