Kenyan long-distance runner Albert Korir, the 2021 New York Marathon champion, has been suspended from professional athletics for five years following confirmed doping violations. The Athletics Integrity Unit (AIU) announced the sanction after Korir admitted to using CERA (Continuous Erythropoietin Receptor Activator), an advanced blood-boosting agent classified as a prohibited substance.
The 32-year-old athlete tested positive for the performance-enhancing drug during three separate out-of-competition tests conducted in October 2025. CERA represents a sophisticated third-generation version of erythropoietin (EPO), designed to increase oxygen-carrying capacity and endurance.
As a consequence of these anti-doping violations, all competitive results achieved by Korir since October 2025 have been nullified. This includes his third-place finish at the November 2025 New York Marathon, where he completed the race in 2:08:58. British athlete Patrick Dever, who originally finished one second behind Korir, will now be elevated to the bronze medal position.
The AIU emphasized that the multiple positive tests demonstrated “clear evidence of the athlete’s use of a prohibited substance on multiple occasions.” Korir received a one-year reduction from the standard six-year suspension due to his timely admission of the violations. His competitive ban will remain in effect until January 7, 2031.
Korir’s career highlights include consecutive runner-up placements in the New York Marathon (2019 and 2023) alongside his 2021 victory, which he completed in 2:08:22. This case follows recent disciplinary action against women’s marathon world record holder Ruth Chepngetich, another Kenyan athlete who received a three-year suspension last October for similar anti-doping violations.
