Former london marathon champion Daniel wanjiru has lost the case at the Court of Arbitration for Sport (CAS) over the anti-doping rule violation.
Wanjiru, who won the 2017 London marathon title had appealed at CAS but his case was dismissed and will serve his four-year doping ban since 2019.
Wanjiru was banned by the Athletics Integrity Unit for an athlete’s biological passport violation after unusually high levels of hemoglobin were detected in his blood sample.
ABP is software that monitors abnormal biological parameters, which may indicate the use of a prohibited substance by the suspected culprit.
In the 2016 Amsterdam Marathon champion’s case, AIU ruled that the high levels had no physiological explanation and could only be a case of doping.
The court, led by Jan Paulsson, concluded that Wanjiru and his lawyers have failed to prove that his samples had been inadequately mixed, leading to a false positive.
“The panel is comfortably satisfied that the abnormal ABP values were caused by a transfusion. The athlete has not provided any objective, physiological or pathological reason or condition to explain the abnormality in the ABP values,” the court ruled.
It added: “The athlete’s appeal is dismissed. Accordingly, his period of ineligibility of 4 years starting on December 9, 2019, and the disqualification of his results from March 9 2019 stand as ordered by the Disciplinary Tribunal.”
