AIU Bans 2021 NYC Marathon Champion Albert Korir for Five Years After Doping Admission

The case spotlights stricter AIU penalties driven by multiple positives under early-admission rules.

Overview

  • Albert Korir received a five-year ban announced Monday, running from January 8, 2026 to January 7, 2031 following a provisional suspension that began in January.
  • Korir admitted violations after three out-of-competition tests in Kenya in October 2025 found CERA, a long-acting drug that boosts red blood cell production similar to EPO.
  • All results from October 2025 are disqualified, including his third-place finish at last November’s New York City Marathon, while his 2021 New York title remains intact.
  • The AIU treated the multiple positives as an aggravating factor that pushed the standard four-year term to six before cutting one year for his early admission and acceptance.
  • He waived a hearing and accepted the sanction, and media reports indicate Patrick Dever is elevated to third in the 2025 New York race as the ruling echoes recent Kenyan marathon bans such as Ruth Chepngetich’s.
