Athletics: Kenya’s marathoner Albert Korir handed five-year ban for doping violation

Kenyan long-distance runner Albert Korir has been handed a five-year ban after testing positive for a prohibited performance-enhancing substance, adding to growing concerns over doping in Kenyan athletics.

The sanction was confirmed by the Athletics Integrity Unit, which revealed that Korir tested positive for synthetic erythropoietin (EPO) during an out-of-competition test conducted in Kenya in October.

EPO is a banned substance that boosts the production of red blood cells, enhancing endurance by improving oxygen delivery to muscles—an advantage particularly significant in long-distance running.

Initially facing a six-year suspension, Korir received a one-year reduction after admitting the violation and accepting the sanction early.

As a result, his ban runs from January 8, 2026, when he was provisionally suspended, until January 7, 2031.

Korir, 32, rose to global prominence after winning the New York City Marathon in 2021 with a time of 2:08:22.

He later achieved a personal best of 2:06:57 while finishing third in the 2023 edition of the same race.

He also claimed victories at the Ottawa Marathon in 2019 and 2025, establishing himself as one of Kenya’s consistent performers on the international marathon circuit.

His suspension comes at a time when Kenya continues to grapple with a doping crisis that has cast a shadow over its reputation as a powerhouse in long-distance running.

The country has faced intense scrutiny since the period leading up to the 2016 Rio Olympics, when widespread doping violations led to warnings and sanctions from global anti-doping authorities.

According to data from the AIU and the World Anti-Doping Agency, more than 140 Kenyan athletes—predominantly distance runners—have been sanctioned for doping offences over the past decade.

These cases have prompted stronger testing regimes and government-backed reforms aimed at restoring credibility in the sport.

Korir’s case follows other high-profile sanctions, including that of Ruth Chepngetich, the women’s marathon world record holder, who received a three-year ban after admitting the use of hydrochlorothiazide (HCTZ), a diuretic commonly used as a masking agent.

In a further sign of tightening enforcement, Kenyan authorities in June 2024 issued their first lifetime ban to marathon runner Beatrice Toroitich, while 10km world record holder Rhonex Kipruto was handed a six-year suspension.

Sports analysts say Korir’s ban underscores both the persistence of doping challenges and the increasing effectiveness of anti-doping efforts.

While the crackdown has led to a growing list of sanctioned athletes, it also signals a stronger commitment by authorities to protect the integrity of competition.

As Kenya continues its efforts to rebuild trust in athletics, cases like Korir’s highlight the ongoing battle between performance pressure and fair play in one of the country’s most celebrated sporting disciplines.
