Farah talked about how he wants to move up to the marathon after the 2017 World Champs and talked about the 5000 WR.
On the 5000 WR:
"It's possible - I have thought of it and I do want to give it a shot but sometimes you have got to be honest with yourself and look at yourself.
"There are barriers. A guy like me, yes, I am good in terms of championship races and that's where I dominate - but in terms of running fast times I haven't quite done that.
"I've run 12'53 and you have to go under 12'50 and then you have to go 12'45 and beyond. The world record is 12'37. It's incredibly, incredibly hard and I will give it a shot but you've got to be honest with yourself. It's not an easy record.,,,
"Could I do a world record right now...could I do it straight away? No."
