Mo Farah will not end his relationship with Alberto Salazar after saying he has “not seen any clear evidence” that his coach has been involved in doping.
However, the British Olympic and world 10,000m and 5,000m champion said he would be the “first to leave” if the allegations against Salazar were true.
UK Athletics has “no concerns” over the pair working together after allegations were made in a BBC investigation.
There is no suggestion Farah has done wrong and Salazar denies the claims.Farah spoke to Salazar on Friday and says he want answers from the American “as soon as possible”.
“I’m really angry at the situation,” said the 32-year-old. “It’s not right or fair. I haven’t done anything but my name is getting dragged through the mud.
“I need to know what is going on, are they true or not? If they turn out to be true I will be the first person to leave him.”
Farah, who won 5,000m and 10,000m gold at the London Olympics in 2012, admitted the controversy had “affected” him before he races in Birmingham on Sunday.
“My reputation is getting ruined. You guys are killing me,” he told a news conference.
“I’m a clean athlete. I’m against drugs 100% and believe anyone caught should be banned for life.”
