More quotes from British sprinter Adam Gemili  who feels he has learned a lot by watching the best sprinters in the 100m final.

He tells BBC Sport: "I'm always learning and improving. Hopefully as I get older I can go out and compete with these guys. I just have to train hard. If I was out on the start line hopefully I would've got into the final but it was not to be."

British sprinter  Adam Gemili, who is out in China, but will not compete in the 4x100m relay because of injury, has been talking to BBC Sport.

He says: "My injury is better now, it's more a precaution to not run. We've got a few big years coming up but if I went out and did something silly then that would put me further back.

"Watching last night's 100m was so cool. It has been a wicked experience out here. With Bolt you always have to believe in this guy and never write him off. Gatlin just fell apart but what a race to witness."

Usain Bolt places his video recorder (are they still called camcorers?!) on the podium step as he is presented with a red bouquet and his ninth world championship gold medal. Where would the sport be without him? What will the sport do when he's gone?

"It was an atmosphere like no other in the 100m final and, apart from Usain Bolt, all the experienced athletes crumbled under the pressure. It was telling that the two most inexperienced athletes took bronze ahead of Gay, Powell and others."

Mike Costello
BBC Radio 5 live athletics commentator

"Usain Bolt, the greatest athlete of all time, the man who secured such a significant victory for his sport, stands alone above all others with nine gold medals at World Championships."

More hi-jinks and tomfoolery as Usain Bolt films a video selfie before stepping on top of the podium to sing the Jamaican national anthem.   

Track and field's principal showman, Usain Bolt, is back on the track where winning has become routine, preparing for the 100m medal ceremony and the Jamaican has a video camera in his hand, filming the moment. 

It has been a successful morning for Britain's Olympic champion Greg Rutherford, who qualified second for Tuesday's long jump final.

The 28-year-old jumped 8.25m, with American Jeff Henderson, the leading long jumper this year, recording 8.36m.

Rutherford has gone on Twitter, well, asked his girlfriend to do so, and posted this message.

"Christine Ohuruogu is a solid performer and has relied on that throughout her career. She is not one of the fastest runners this year but will use this race to get into shape.

"She ran a very even-paced race. She has got really good technique, is a very powerful runner and has great upper-body strength. If there is any athlete that I don't worry about, it is Christine. She will always be right there."

While you were hopefully tucked up in bed, a few British athletes were making progress in Beijing.

Olympic long jump champion Greg Rutherford reached Tuesday's final, finishing second in qualifying.

Defending champion Christine Ohuruogu moved on to the 400m semi-finals by winning her heat, with fellow Briton Anyika Onuora also going through in a personal best time of 51.14secs.

And Holly Bradshaw recorded a season's best of 4.55m to finish joint top of qualifying  in the pole vault.

Talking of heptathletes, Katarina Johnson-Thompson had a horrible day yesterday, as she broke down in tears after her hopes of a heptathlon medal at the World Championships in Beijing ended in disappointment.

The Briton finished 28th, her chances effectively ending when she failed to record a score in the long jump.

But today she has posted this message on Twitter.

"Jess is a formidable character and she loves to compete. When she stepped back on the track again she realised this is her home and that's what spurred her on."

Are there tears? A few droplets in the corner of the eyes, but Britain's most famous mum holds it together as God Save the Queen is played. Her next task is to pose for excitable photographers before she is ushered into the bowels of the stadium, which sounds painful but it isn't. 

Steve Cram
BBC athletics commentator

"As athletes mature, it can often become more difficult for motivation and you have to find different ways of getting back to your best shape. But Jess has managed to do that."

"Gold medallist and world champion, representing Great Britain and Northern Ireland..." says the announcer, and Jessica Ennis-Hill smiles. The Olympic and world champion's name rings out and she steps on top of the podium, the best in Britain, the best in the world. 

Jessica Ennis-Hill is back in the Bird's Nest, awaiting collection of a precious metal from Prince Albert of Monaco. If there's a sporting event, Prince Albert is usually there. His employers must have a generous leave system. 

As has become tradition at this time of day, we're giving you the opportunity to vote. (I know, we do spoil you.) 

Today's question is: Will Usain Bolt and Mo Farah do the double in Beijing? You have four options to choose from so, go ahead, get voting and we'll reveal the results later this afternoon.
