Mo Farah said that it was "hard work" winning today's 5,000 metre final at the World Championships, adding that it was "harder than the last".
He told the BBC:
I never thought in my career I would achieve something like this. This is something I've worked so hard for. All I was thinking about was my kids and how much I've been away from them.
It was hard. It was a lot more hard work than the last, I put so much hard work into it.
Mo Farah is hailed as Britain's greatest ever athlete after repeating his Olympic success with a double victory at the World Championships.
He won two Olympic gold medals last year and has already won gold this year in the 10,000 metres but is he the greatest of all time?
