Mo Farah has told how "everything just came together for me" as he became double Olympic champion.
Speaking the morning after he added the 5,000m gold to his 10,000m title won last Saturday night, Farah felt all his hard work had finally paid off. He said double gold was a fitting comeback from the "big disappointment" of failing to make a final in Beijing four years ago - but added he could not have done it without the deafening support of the crowd.
He told the BBC: "As an athlete you dream of becoming an Olympic champion but, for me, to become Olympic champion twice is just an unbelievable feeling."
He added: "If it wasn't for the crowd I don't think I would have been up there, for sure. They make a big difference. In front of 80,000 people just cheering your name and getting louder and louder, it's the best feeling ever, it's just like being at a football game."
He said he felt he was able to dictate Saturday night's race and he "knew I had it in me" to be first over the finish line.
On his remarkable progress over the last four years, Farah added: "It's been a lot of hard work and grafting. In Beijing, for me it was really disappointing. I had to move forward and recover and get into my running again, and then last year I made the big decision to move to the US."
He went on to say: "There is a decision in your career you have to make...I'm glad I made that decision, and it just shows you it works.
"But a lot of miles have gone into these legs, week in, week out, over 100 miles, sometimes I'd be hitting 120 miles, so it just shows you it's hard work. There are no short-cuts, just hard work and grafting."
Asked what his achievements in London mean to him overall, Farah said: "To be double Olympic champion, to be on the podium, it's the best thing.
"There is no word to describe it because all the work, all the sacrifices, all the things you put into it, it's just unbelievable."
