Kenyan distance runner Rhonex Kipruto, the 10-kilometre road running world record-holder, has been suspended for suspected doping, the Athletics Integrity Unit said Wednesday.
Kipruto, who also won a bronze medal in the 10,000-meter race at the 2019 world championships, has been notified of a charge relating to irregularities in his athlete biological passport, the AIU said.
The biological passport can detect possible irregularities in blood values assessed over time without an athlete testing positive for a banned substance. The 23-year-old Kipruto was suspected of using a banned substance or method, the AIU said.
