An irritated Mo Farah said he will never fail a drugs test and accused journalists of making "something out of nothing" as he faced more probing over doping allegations.
The four-time Olympic champion thrilled the crowd at the London Stadium on Sunday when he won the 3000 metres at the Anniversary Games in his homeland.
Farah's latest victory came at the end of a week in which the 'Fancy Bears' hacking group released a document that claimed his biological passport once flagged up unusual results, before he was later cleared.
The Brit's spokesperson said any suggestion of misconduct made in a document claimed to have been taken from an IAAF database - three months on from world athletics' governing body confirming it had been the victim of a cyber attack - were "entirely false and seriously misleading".
And the 34-year-old expressed his frustration at being asked about the allegations just days after the IAAF apologised to the athletes named by the 'Fancy Bears' and the governing body said there was no evidence that he was guilty of wrongdoing.
"I am sick of repeating myself. You guys just make something out of nothing." he told reporters.
"I will never, ever fail a drugs test. I work hard at what I do and I just carry on enjoying what I do. What I do day in and day out, there are no secrets to what I do. My life is not as easy as people think - it is hard work, about grafting.
"I wish you guys would understand it a bit more and write down the facts."
He added: "People who know me and do what I do and love the sport and what we do, day in and day out, in terms of our system and what we do, as I say, I am sick of repeating myself year after year,
"I do what I do with a love and a joy. I can only control my legs and what I do, and I know there are a lot of people who support me, behind me, the whole nation.
"It is just a small minority who think to become a success you must be doing something. I said I will never fail a drugs test. That is who I am. I believe in clean sports and I just have to enjoy what I do, keep smiling."
