Brendan Foster
Olympic medallist and BBC athletics commentator"That was a great race. Mo Farah was tested, but he followed every move. It was a fantastic performance. The Mo Farah we know and love is celebrating. It was an absolute pleasure to watch that race. He might end up being regarded as the greatest distance runner there's ever been."

Steve Cram
BBC athletics commentator"They've thrown everything at him. They've gone hard - but it's not enough. Nothing they had could come close to Mo Farah's pace, strength and ability. He had his wits about him. When he sniffed that gold medal, nobody was going to take it away from him."

Steve Cram
BBC athletics commentator"Tripping Mo up might be one way to stop him. What's happening there is that the panic is starting to set in among the pack. They're bunching up. Geoffrey Kamworor hasn't done enough."

"Not hard enough," says Steve Cram of the Kenyans' effort to tire Mo Farah,. The Briton second, waiting, planning his crowning move. Galen Rupp in the mix, too, in fifth.

Brendan Foster
Olympic medallist and BBC athletics commentator"The pendulum is swinging towards Farah because Geoffrey Kamworor is having to lead so much. This is the hardest Farah has had to run in a major championship. But is he a championship runner? We know he is."

'It's a relentless pace'published at 14:10
Steve Cram
BBC athletics commentator"The pace has been hard and relentless, but it may have to get quicker. If the front-runners want to drop Farah, they'll have to go faster."

Women's marathon world record holder on BBC TV"Mo is just sitting there comfortably, on Galen Rupp's shoulder, and he's doing everything he needs to do without using too much energy."
Farah fourth, in controlpublished at 14:09
"I think early on they will try to do something to burn me out – or perhaps even tire me out for the 5,000m next week," said Mo Farah ahead of this race. The Briton was right, the Kenyans and Ethiopians upped the ante after the second lap but they need to continue to turn the screw if they are to continue to test the double world and Olympic champion.
Galen Rupp moving to third, Farah now fourth... Geoffrey Kamworor and Paul Tanui leading but they must do it all on their own if they are to gang up on the Briton. No Ethiopians in sight, they've fallen by the wayside.

10,000m final
Mo Farah has closed the gap on the leaders and, approaching the halfway mark, is seventh, on the shoulder of his training partner Galen Rupp. Geoffrey Kamworor leading through 5,000m... and they're slowing, which benefits the defending champion Farah.
'The way to beat Mo is to tire him out'published at 14:02
Brendan Foster
Olympic medallist and BBC athletics commentator"Apart from Mo Farah, there's no great champion in here in terms of winning on the track. But there's some good strong running here from the field. Maybe the Kenyan runners have looked at the mistake they made in the marathon this morning.
"They're running more aggressively. Mo hasn't often been in a position where he's hurting at halfway. If he gets tired - well, let's see. That's the only way I've seen him beaten."

A speedy start in the final, running through a 67-second lap with now 18 to go.
Who could be Farah's biggest threat? Mr Brendan Foster has already mentioned Kenyan world-cross country champion, Geoffrey Kamworor, while his compatriot Paul Tanui is also a dangerous runner.
These finalists running at 27-minute pace, punishing in the humid conditions. Farah allowing the front-runners to set the pace, starting to close the gap on the leaders.
