Overview
- The Athletics Integrity Unit suspended Albert Korir for five years and set the ban to run through January 7, 2031.
- Three samples taken in October during training for New York tested positive for CERA, a lab-made drug that boosts endurance by raising red blood cell counts.
- The AIU treated the findings as continued use and raised the standard four-year sanction to six years before cutting one year because he admitted the offense and waived a hearing.
- All results since October were annulled, including his third place at last autumn's New York Marathon, while his 2021 New York win stands.
- The case highlights ongoing doping problems in elite distance running in Kenya and underscores pressure on the sport’s integrity system.
