Mo Farah is looking remarkably casual for a man who has an appointment with athletics history in the early hours of the morning.

Strolling around the Olympic Village, he has the air of a man who knows his fate - and is quite content about it.

After his imperious victory over 10,000m, Farah is aiming to cement his place in the pantheon of distance running legend.

Not since the Flying Finn Lasse Viren in 1972 and 1976 has a long-distance runner done the 5,000m and 10,000m double at consecutive Olympics.

And Farah is well aware of the weight of that history.

He came through a slow heat to secure his 5,000m final progress, which will have suited him just fine.

Of course, the double is nothing new, he has pulled it off at the last two World Championships, but his nerves are palpable.

He got up from the track to win over 10,000m and nearly took a tumble again in heat. Should he fall in the final, he won’t have the chance to get up and recover.

He said the heat had been a “wake-up job”, that he had been “a little bit distracted” and needed “to get back in the zone and focus”.

But don’t doubt his desire.

“It is possible to win another gold, but you look at the other guys and they’re ready for me,” he said, aware that the target on his back is huge.

“I just have to get myself back in that frame of mind and get ready, but I’m still hungry and I still want it.

No-one is going to give it to you, I’m the one they all want to beat and I’ve only done half my job here.

“I’m nervous, of course, but I’ve been here before, I know what it takes. I know what I have to do. All that experience will go a long way but it won’t be enough on the start line.”

Farah has worked hard to study the greats of his sport, reading up on Viren’s exploits on Munich and Montreal.

And since he was shocked by an Ethiopian he had never even heard of, Ibrahim Jeilan, in the 10,000m final at the 2011 World Championships in Daegu - his last loss at a major - he has left no stone unturned in his preparations.

“I am a geek,” he said. 'I do watch races and I do try and learn something about it, look at it, see what I could do.

“I watch myself a little bit, just try and do my homework a bit. I had to learn the hard way, in Daegu. I didn't even have a clue who he was, nobody knew.”
