Another Bolt gold-medal ceremonypublished at 11:52
Men's 200m final
And the medal ceremonies come thick and fast as it is now Usain Bolt's turn to step on to the top of the podium. Yet again. For a tenth time at a World Championships.
He filmed his 100m medal ceremony with a video camera earlier in the week but has left the camera behind today.
Polite applause for Justin Gatlin from the Beijing crowd as he picks up his second silver medal of the championships.

Women's 400m final
Back in the Bird's Nest and the American flag is raised as Allyson Felix picks up her gold medal after winning in a season's best time of 49.26 seconds.
"I think she is under-rated as an athlete - she shows up at championships and truly delivers," says Michael Johnson on BBC Two.

'They were trying to kill me'published at 11:45
Men's 200m final
So how do you stop Usain Bolt? Justin Gatlin and the rest of the field in the 100m and 200m couldn't find a way, but a Chinese cameraman on a segway found out how. Take him out ankle high from behind. The amazing video is definitely worth watching.
Just as Bolt was minding his own business, celebrating his victory, a cameraman clipped a barrier...
...and crashed into the back of Bolt, sending the champion flying.
Luckily Bolt was OK and saw the funny side of it.
"They were trying to kill me, I don't know what was going on" he joked.
"They are like 'you're winning too much so take him out'.
'We should cherish every Bolt victory'published at 11:43
Men's 200m final
Tom Fordyce
Chief sports writer in Beijing"It was another of Usain Bolt's great conjuring tricks. Coming into these championships Gatlin had run more than two tenths of a second faster over 200m than any other man in the field this year, and almost half a second quicker than Bolt.
"Ten World Championship gold medals now, another in his sights in the sprint relay; six Olympic golds, Rio and the chance for three more less than 12 months away.
"It cannot keep going forever. The current end date is August 2017 and the next World Championships in London. The world records will probably sit untouched for a generation, but the man who set them will one day be gone.
"It is why we should cherish every victory, even as they seem inevitable, every little vignette as the cameras come searching for him before he goes to his blocks, every selfie-laden lap of honour."

Michael Johnson
400m world record holder on BBC TV"Usain Bolt is the best in the world and he does not have any rivals. We have to give him a lot of credit for running in the 100m and 200m - this is the most he has been challenged."

Men's 200m final
Just like all good films, it deserved a sequel.
Bolt v Gatlin. Good versus Bad, or so it was badged up. An Olympic hero versus a disgraced two-time drug cheat.
Good triumphed in the first installment, the 100m on Sunday, but what would happen in the second part - the 200m?
The world waited. And again Bolt delivered. In emphatic style. He stormed to victory in 19.55 seconds - the fastest time in the world this year - with American Gatlin trailing in second in 19.74.

Hellopublished at 11:32
Hello, thanks for joining us and welcome to BBC Sport's live text commentary from day seven of the World Athletics Championships.
Great Britain have won three gold medals so far in Beijing, and we have more chances of medals today.
Three Brits are in the women's long jump final, and teenage sprint sensation Dina Asher-Smith runs in the women's 200m final. We will also see British competitors try to secure their places in the women's javelin, women's 100m hurdles and men's 1500m finals. It is going to be a fun day.
A chance for redemptionpublished at 11:30
Sunday was meant to be the day Katarina Johnson-Thompson had been dreaming of. It was the final day of the women's heptathlon, an event she had been tipped to win a medal in.
But sport can be cruel.
Image source, Getty ImagesThree successive fouls in the long jump saw her fail to collect any points and ended her medal hopes.
The tears flowed as the hopes were dashed.
Image source, Getty ImagesBut now she has a second chance of glory. She has qualified for the women's long jump final and is again dreaming of gold. Will the story have a Hollywood ending? Can she end a tough week on the podium?
