MONACO (AP) — Former London Marathon winner Daniel Wanjiru of Kenya has been banned for four years for doping.
The Athletics Integrity Unit said it was “highly likely” that Wanjiru used prohibited substances, citing abnormalities in his biological passport.
The 28-year-old Wanjiru’s four-year ban ends Dec. 8, 2023.
Wanjiru, who had been provisionally suspended in April, won the London Marathon in 2017 and the Amsterdam Marathon in 2016.
A blood test from March 9, 2019, showed an “extraordinarily high” hemoglobin level, the AIU said.
“We therefore confirm our previous opinion that it is highly unlikely that this profile is the result of a normal physiological or pathological condition, and it is highly likely that it was caused by the use of prohibited methods, with or without the use of prohibited substances,” the AIU said in its findings.
