Former New York Marathon winner Albert Korir has been banned for five years after admitting to doping. The 32-year-old Kenyan tested positive for CERA, a strong blood-boosting drug, in three out-of-competition tests in October 2025.
All of Korir’s results since October, including his third-place finish in last November’s New York Marathon, are now disqualified. The Athletics Integrity Unit (AIU) said his ban will end on 7 January 2031, after a one-year reduction for admitting the violations.
Korir had previously been runner-up in 2019, won the New York Marathon in 2021 with a time of 2:08:22, and finished second in 2023 and third in 2024. The AIU confirmed the positive tests showed clear use of banned substances multiple times.
Last October, Ruth Chepngetich, the women’s marathon world record-holder, was also banned for three years for doping.
