Two-time world champion Shelly-Ann Fraser-Pryce has a champion's hairstyle. 

There's talk the green-dreadlocked great could run 10.60 - only three women have ever dipped under 10.70 in the 100m and no-one has done so since 2009. Can the Jamaican do it?

Here are the contenders, featuring the big names... defending champion Shelly-Ann Fraser-Pryce, European champion Dafne Schippers, America's Tori Bowie... and I could go on. 

If the women's 100m finalists can finish with the elan of Ezekiel Kemboi we will have experienced a wonderful race. 

The fastest women in the world, who also happen to have the best haristyles in the world will burst out of the blocks at around 14:35 BST, which is pretty soon really. 

Earlier we asked if you think Usain Bolt and Mo Farah will do the double and the majority of you think both will - 69% of you in fact.

Thanks for voting.

"That was absolutely amazing from Ezekiel Kemboi. You don't win four world titles and two Olympic Games without being the very best. He is a great athlete and a character of the track."

Blimey. An incredible turbo-charged burst of speed from Ezekiel Kemboi after the bell and the Kenyan overtakes everyone and maintains his pace to capture a fourth consecutive world title. An astonishing sprint finish, clocking 8:11.28 to win. 

Predictably, it was a Kenyan top three, with Conseslus Kipruto (8:12.38) second and Brimin Kiprop Kipruto (8:12.54)  joining them on the podium. 

American Evan Jager, who looks more like a decathlete such is his stature, is ranked second in the world this year and bursts into the lead at the bell... but he's quickly overtaken and his chances are gone, gone, gone... 

"It's going to be a sprinter's race," says Brandan Foster of the men's 3,000m steeplechase final. 2013 World silver medallist Conseslus Kipruto is leading the bunch. Blond American Evan Jager is by his side.

Both Shawnacy Barber and Raphael Holzdeppe fail to clear 6.00m after three attempts which means gold will be awarded to young Canadian Barner, who cleared 5.90m with his first attempt.

Here's how close a finish it was between compatriots Molly Huddle and Emily Infield. I guess a distance runner does not usually have to master the dip finish.

And now after that drama we have the 3,000m steeplechase final under way. Ezekiel Kemboi bidding for a fourth consecutive world title. He's one of four Kenyans in the final, but no British athletes I'm afraid.

Britain's Kate Avery, fourth at last year's Commonwealth Games, comes home in 15th in 32:16.19

"I cannot believe what I have just seen! Run through the line! Molly Huddle's team-mate Emily Infeld pips her right on the line and takes bronze. She has handed that to Infeld. She will regret that for the rest of her life, she relaxed on the line and is absolutely distraught."

Richard Butler:, external Huddle... You should run through the line.

Ethiopia's Gelete Burka (31:41.77) must settle for second, while America's Molly Huddle, who did all the hard work in the final laps, pushing the others on, is beaten to the line in a sprint finish by her compatriot Emily Infeld (31:43.49). Tears for Huddle, who slowed thinking bronze was hers, joy for her team-mate. Sport can be cruel. 

It's Kenya versus Ethiopia, Gelete Burka versus Vivian Cheruiyot... the pair scrap it out coming down the home straight and it's the Kenyan Cheruiyot who is the stronger, winning in 31:41.31. The Kenyan now a four-time world champion.

We're into the final stages of the women's 10,000m... the final bell tolls and there are seven athletes in contention... Vivian Cheruiyot in contention...

Excitement in the pole vault final. Defending champion Raphael Marcel Holzdeppe has one final chance to clear 5.90m - and he does it! 

The final now a showdown between the German and Canada's Shawnacy Barber. Renaud Lavillenie has been confirmed as the bronze medallist, which is not what he came to Beijing for.
