Mo Farah: It is not right or fair, I am 100% clean

An investigation by the BBC television programme Panorama in association with American website ProPublica alleged that Salazar had given Farah's training partner Galen Rupp the banned anabolic steroid testosterone.

While there was no suggestion or evidence that Farah has broken any rules, the double Olympic champion took to his Facebook page strenuously denying that he has ever taken performance-enhancing drugs.

The furore has continued, though and Farah spoke to Sky Sports News regarding the media storm about Salazar.

Asked whether he had ever taken or been advised to take testosterone, EPO (human growth hormone) or thyroid medication to assist his performance, Farah said: No, never.”

“For people to think I have taken shortcuts; it’s not right or fair. I am 100% clean.” added an emotional Farah.

“I put my body through hell, I run 120 miles a week.”

However, he did say that if it is proven that Salazar had crossed the line, then he would immediately cease their relationship.

"If more people come out and it’s proven that he’s crossed the line then I’ll be the first person to come out," said Farah.

"I work every day and every year I spend seven months away from my family. I miss my kids’ birthdays and those are times I will never be able to go back on and share with them. That kills me," Farah told Sky Sports News HQ.

"To be labelled a cheat – it’s not fair. If I’m a cheat then prove I’m a cheat or just leave me alone and let me do what I do best.

"That’s to run and represent my country and make my country proud. There were 75,000 people at the London (Olympics) cheering me on and shouting my name. I will never let them down but people need to know the truth."

Farah could not be clearer. He has done no wrong and sees no reason to leave Alberto Salazar’s stable until it has been proven that his coach as done wrong. Farah appears to feel that he has been smeared by association – there is no evidence that he has done any wrong and, as he rightly states, allegations have been made against his coach but nothing has been proven.

He was bold and bullish and provided a clear message. He has done nothing wrong.
