New York, NY – Former New York City Marathon champion Albert Korir has been handed a five-year ban from competition after admitting to a doping violation, the Athletics Integrity Unit (AIU) announced Monday. The 32-year-old Kenyan runner, who won the prestigious marathon in 2021, tested positive for CERA, a prohibited substance, in multiple out-of-competition tests last October.
The ban effectively ends Korir’s competitive career for the foreseeable future, stripping him of any results achieved after his initial positive test in early October 2025. Korir’s consistent presence at the top of major marathons, including five podium finishes at the New York City Marathon between 2019 and 2025, now comes under a shadow.
CERA, or Continuous Erythropoietin Receptor Activator, is a synthetic form of EPO, a performance-enhancing drug that stimulates red blood cell growth, thereby improving endurance. The AIU cited “compelling evidence” of repeated leverage, noting the multiple positive tests as a significant aggravating factor in the length of the suspension. Even as the initial five-year ban was issued, it was reduced by one year due to Korir’s admission of guilt.
Korir’s victory at the 2021 New York City Marathon came in a time of 2:08:22. He consistently proved a formidable competitor in the World Marathon Majors, securing second-place finishes in New York in 2019 and 2023, and a third-place finish in 2025. He similarly achieved notable results at the Boston Marathon, finishing fifth in 2024 and fourth in 2023. His personal best remains 2:06:57, set at the 2023 New York City Marathon.
The AIU’s decision underscores the ongoing battle against doping in elite athletics, particularly within Kenyan distance running. According to reports, Kenya currently has the highest number of athletes under provisional suspension, with 140 out of 683 sanctioned athletes globally originating from the East African nation – representing 20.5 percent of the total. India follows with 137, and Russia with 75. The United States has 15 athletes currently sanctioned.
This case arrives amidst broader scrutiny of anti-doping efforts in Kenya. In September 2025, the World Anti-Doping Agency (WADA) declared the country’s anti-doping agency “non-compliant” with the WADA code, though the status was later changed to “watch list” following demonstrated improvements. The recent suspension of marathon world record holder Ruth Chepngetich for three years after testing positive for HCTZ further highlights the challenges facing the sport.
While the situation presents a serious concern, some within global athletics organizations believe Kenya is making strides in addressing the issue. Despite the high number of current suspensions, there is a growing sense that the country is actively working to strengthen its anti-doping measures and combat the problem at its source.
Korir is now ineligible to compete in any sanctioned athletics event until January 2031. The AIU’s ruling serves as a stark reminder of the consequences of doping and the commitment to maintaining the integrity of the sport. The case also raises questions about the effectiveness of current anti-doping protocols and the need for continued vigilance in protecting clean athletes.
The incident will undoubtedly impact the competitive landscape of marathon running, removing a consistent contender from major races. Fans and fellow athletes alike will be watching closely to see how this case influences future anti-doping efforts and the ongoing pursuit of fair play in the sport.
What’s Next: The focus now shifts to the upcoming marathon season and the continued efforts of the AIU and WADA to ensure a level playing field for all athletes. Further updates on Kenya’s anti-doping progress will be closely monitored by the international athletics community.
