Albert Korir, a former winner of the New York City Marathon, has been handed a five-year suspension after admitting to using a banned substance.
The decision was confirmed by the Athletics Integrity Unit.
Positive Test for Performance Enhancing Drug
Officials revealed that the 32-year-old athlete tested positive for a synthetic version of erythropoietin, commonly known as EPO.
The test was conducted out of competition in Kenya in October 2025.
EPO is known for boosting red blood cell production, which can enhance endurance performance.
Admission Leads to Reduced Suspension
Korir admitted to the violation early in the process.
As a result, his initial six-year ban was reduced by one year.
Authorities stated that the reduced penalty reflects his cooperation and acceptance of the sanction.
Ban Timeline and Career Highlights
The suspension officially began on January 8, 2026.
It will remain in effect until January 7, 2031.
Korir gained international recognition after winning the 2021 New York City Marathon with a time of 2:08:22.
He also secured third place in the 2023 edition with a personal best of 2:06:57.
In addition, he claimed victories at the Ottawa Marathon in both 2019 and 2025.
Impact and Consequences
The ban sidelines Korir during key competitive years of his career.
He will be unable to participate in major international races during the suspension period.
The case also adds to ongoing concerns about doping in long distance running.
It may influence stricter testing and enforcement measures in the sport.
What’s Next?
Korir will serve his suspension until 2031.
He may attempt a return to competition after the ban expires.
Athletics authorities are expected to continue monitoring and enforcing anti doping regulations.
Summary
Albert Korir has been banned for five years after testing positive for a banned substance.
The sanction was reduced due to his early admission.
His suspension will run until 2031, pausing a career that included major marathon victories.
