"Mo's impact, Mo's quality, Mo's medals is letting these athletes know he is there. It is affecting them. He is turning this race by his very presence."

Ah, Farah's just headed off for a drink at the table out in lane nine. Let's just say he's quite relaxed about how things are going. The drinks have been moved to lane three - er, a bit close for comfort.
We have gone through 1600m.

"Mo is about 12 minutes away from what could be his most glorious moment."
Mo Farah is settled in this 15-man field right at the back. His team-mate Tom Farrell leads after the first lap.

"This will require all of Mo's concentration and all of his tactical prowess.
"Let's not forget Tom Farrell too. He was delighted with his performance in the heats and so he should be."

"The shape he is in at the moment. He is pretty much unbeatable. Even when he trips, he trips forwards so he does everything perfectly. He can just control that race perfectly."

Mo this, Mo that, let's not forget there is another Brit in the 5,000m final - Tom Farrell.
The Cumbrian 24-year-old, who trained at Oklahoma State University, missed out on London 2012 because of injury. He has already made the most of this opportunity by qualifying for the final.

In the same Bird's Nest stadium where he went out in the Olympic 5,000m heats seven years ago, Mo Farah will tonight attempt to change all that. The danger men are likely to be Kenya's Caleb Ndiku, with the assistance of his Kenyan team-mate Edwin Soi, and Ethiopia's Hagos Gebrhiwet; it's a warm, sticky evening here, and Farah must once again stay cool under the most immense pressure."

That was a superb performance from Oskan-Clarke. She has the perfect seat to watch team-mate Mo Farah go for the triple-double. Ready?
Shelayna Oskan-Clarke talking to BBC Sport after running one minute, 58.99 seconds: "I am really happy. There is not much more I can say. Everyone has been really supportive and saying how proud they are.
"I'll go away and do some more training. It was good to come here and get this experience. I am happy with what I have achieved here."

"Oskan-Clarke battled so well, losing out on fourth just on the line. A fine first international apperance. She should be so proud of herself. This lady is going to go a long way."
Steve Cram
BBC athletics commentator
"Fifth place in the world championships for Oskan-Clarke was something she would not have dreamed of at the start of the season."
Image source, BBC SportWell, what an epic battle down the home straight.
Belarus athlete Marina Arzamasova pips Canada's Melissa Bishop (silver) and Kenya's Eunice Sum (bronze) to win in 1:58.03. The 2013 champion Sum will be disappointed - had not much left in the tank in the last 50m.
Briton Shelayna Oskan-Clarke was boxed in with 250m to go when she looked like she wanted to strike.
Shelyana Oskan-Clarke is perfectly placed with a lap remaining - she's about fourth.
OK. Surely Oskan-Clarke won't win a medal here? Surely. We're off.
