Kenyan Olympic Finalist Handed Four-Year Doping Ban

Nairobi — Kenyan long-distance runner Benard Kibet Koech has been banned from competition for four years after anti-doping authorities found biological abnormalities consistent with blood doping, athletics officials confirmed.

The Athletics Integrity Unit (AIU) said the sanction followed an investigation into irregularities detected in Koech’s Athlete Biological Passport (ABP) — a system that monitors changes in an athlete’s blood markers over time to identify potential doping practices.

Koech, 26, finished fifth in the men’s 10,000 metres at the Paris 2024 Olympic Games. The AIU confirmed that the Olympic result has now been officially disqualified.

Biological Passport Findings

According to the AIU, blood samples taken around the Kenyan Olympic Trials and during the Paris Olympics showed unusually elevated haemoglobin levels. An independent panel of experts reviewed the data and concluded that the fluctuations were highly suggestive of blood manipulation.

The ABP system does not detect banned substances directly. Instead, it identifies abnormal biological patterns that cannot be reasonably explained by natural physiological changes.

Koech’s legal team argued that the irregular readings were caused by a combination of altitude training, iron supplementation, and a previous COVID-19 infection. However, the expert panel rejected these explanations, ruling that they did not sufficiently account for the data patterns observed.

Career Impact and Wider Context

Before his provisional suspension in 2025, Koech was ranked among the world’s elite distance runners and previously held a world record in the 10-mile road race.

The case adds to growing scrutiny of Kenya’s athletics programme. Anti-doping authorities report that more than 150 Kenyan athletes are currently serving bans for doping-related violations, placing the country under increased international pressure to strengthen compliance and testing regimes.

The AIU said it remains committed to protecting the integrity of endurance events, where blood doping has historically posed a significant challenge.
