Kenyan champion tests positive

Olympic and three times 1500m world champion Asbel Kiprop has reportedly tested positive for a banned substance.

The Kenyan, who 10 years ago beat Kiwi silver medallist Nick Willis at the Beijing Olympics, is widely regarded as the finest 1500m runner of the last decade.

In a statement, Kiprop said he would not ruin his career by doping.

‘‘I would not want to ruin all I have worked for since my first international race in 2007. I hope I can prove that I am a clean athlete in every way possible,’’ Kiprop said.

‘‘I have been at the forefront of the fight against doping in Kenya – a fight I strongly believe in and support.’’

Kiprop’s agent, Federico Rosa, said he was aware of the rumour but was ‘‘still trying to get confirmation’’, when contacted by The Daily Mail. However, senior athletics sources have confirmed the 28-year-old failed an out of competition test.

A report in Kenya on Tuesday said a high profile runner who has ‘‘dominated world championships over the years’’ was embroiled in a doping scandal.

It also claimed, while there was no confirmation from the Anti-Doping Agency of Kenya (Adak) or Athletics Kenya (AK), that the substance was the same blood-boosting drug used by disgraced Kenyan Jemima Sumgong.

Sumgong, who won the women’s marathon at the Rio Olympics, last year tested positive for EPO and was subsequently banned for four years.

Even if Kiprop is found guilty of doping, it’s extremely unlikely Willis will have his silver medal upgraded to gold because any ban would likely only be backdated a couple of years.

Kenya has been stung by a rash of positive tests in recent years.

Between 2012 and 2016, 40 cases were reported, including marathon gun Rita Jeptoo.
