Mo Farah has announced in a statement that he will continue to work with coach Alberto Salazar, who has denied doping allegations.
The coach issued a 12,000-word statement disputing claims made by BBC Panorama and investigative website ProPublica that he violated several anti-doping rules. Farah says he believes in the evidence provided by Salazar and will continue to work with him.
Double Olympic champion Farah said on his official Facebook page: "Following all the speculation I want to make it clear where I stand. Although it's been a difficult time, I asked Alberto to respond to the allegations made against him and he has now done so in full.
"As someone I've worked with for many years, I feel I have to believe in Alberto and the evidence he has provided. Based on that evidence, I will continue to work with him and hope now that I can focus on what I do best - training hard to win medals for my country."
Salazar has been at the centre of recent doping allegations along with Farah's training partner Galen Rupp, who also denies any wrongdoing.
Salazar also previously denied his relationship with Farah, who recently travelled to his American training base to seek answers from his coach, had broken down. The Brit said he had been "reassured" by his coach that the allegations are false.
Farah, who has not been accused of anything illegal, came under scrutiny after a report in the Daily Mail claimed he missed two drugs tests in the build-up to the London 2012 Olympics, where he won 5,000 and 10,000m gold.
On Wednesday, a report claimed the US Anti-Doping Agency (USADA) is investigating whether Salazar encouraged Rupp and others to skirt anti-doping rules. USADA is reportedly still investigating the case.
Rupp won his seventh successive 10,000m race at the US Championships on Thursday, before his coach Salazar afterwards.
