Women's 4x100m final
Sums up the championships for Britain.
The USA win their third successive world title in the women's 4x100m, just ahead of Jamaica who sent Shelly-Ann Fraser-Pryce into the sunset with a silver.
Bronze for Germany, edging out the Brits. So that's no medals from the relays at all for GB. Very disappointing.
Women's 4x100m final
The USA are seeking a hat-trick of world titles.
Jamaica are powered by the emotion of Fraser-Pryce.
And Britain have a strong team.
Who will take the gold?
We'll know in a minute...

Can she do so with global medal number 25?
The tributes have been flooding in throughout the championships, including from eight-time Olympic champion Usain Bolt.
Although he has nothing but respect for his compatriot, his one complaint is that Fraser-Pryce has kept going long enough to make him look bad, eight years after he retired aged 30.
"There are no words to explain how great Shelly-Ann is," Bolt told BBC Sport.
"She's a legend in my book, she has proven again and again that she is one of the best in the world.
"She left, had a kid, came back to the sport and still dominated. I'm happy to know and to see this greatness."

Amy Hunt is going to elevate the team and she's coming off a great high from that 200m [silver medal].
They ran really well in qualifying, they're looking strong and we've not got a gold medal yet. I'm not putting too much pressure on and I'm not going to jinx it but I hope this 4x100m women's team can step up here.

Fair to say it was mixed fortunes for Britain in the 4x100m relay heats on Saturday...
GB women through to finals but men blunder handover
As the rain picks up again in Tokyo, the women's high jump final has been paused just as we approached the conclusion.
No action in the men's discus either, which had not resumed after the first delay.
But on the track, the relays will continue...

Great Britain's Dina Asher-Smith, Success Eduan, Desiree Henry and Daryll Neita qualified for the women's 4x100m relay with a good showing in Saturday's heat.
The team has been changed for the final though, with world 200m silver medallist Amy Hunt coming for Eduan as she eyes a second medal of the week.
They won silver in Paris last summer, and the nations they finished on the Olympic podium alongside - USA and Germany - will likely provide the stiffest opposition again.

We're down to the final three in the women's high jump.
Favourites Nicola Olyslagers (Australia) and Yaroslava Mahuchikh (Ukraine) - who passed at 2m after failing her first attempt - are joined by Poland's Maria Zodzik, who cleared the height at the final attempt.
What a time to produce a personal best. She's guaranteed a medal.

GB athletes get few chances to grab the sporting limelight and they deliver this. Too many sub par performances and excuses. The whole set up needs looking, especially field events which are abysmal.

It has not been as successful a day - or a championships - as we would have hoped from a British perspective.
But the GB team did pick up two medals earlier in a dramatic 800m...
GB duo take silver and bronze in 800m finals
Men's 4x400m final
GB's Toby Harries speaking to BBC Sport after finishing sixth: "The shoes are heavy from the rain so it's always going to be a little slower but I think, we're born and bred in this, we're British we have to deal with rain so in a way it benefits us.
"But today we just weren't good enough. We'll suck it up and next year we'll be back in that medals table."
Men's 4x400m final
GB's Charlie Dobson speaking to BBC Sport after finishing sixth: "I mean there was quite a decent gap to fifth, unfortunately we just weren't in a position to fight for anything.
"But I want to say a massive thank you to our sponsors - they've been a massive help for us getting here and we will definitely be back and one day get that medal."
Men's decathlon final
Image source, Getty ImagesGermany's Leo Neugebauer hangs on for the gold medal! He was labouring at the back end of the 1500m but gets over the line just in time to pip Ayden Owens-Delerme (Puerto Rico) to the title by 20 points.
Neugebauer, the Olympic silver medallist, wins with a season's best 8804 points.
USA's Kyle Garland takes the bronze medal.
Men's 4x400m final
GB's Lewis Davey speaking to BBC Sport after finishing sixth: "It is [a well drilled unit] and we practice a lot so we have a good group of lads and we don't really have an excuse. It wasn't great with the conditions but I thought that was absolutely dreadful.
"I don't know about the other lads but my running felt absolutely dreadful."
Image source, Getty ImagesThe women's high jump final is back under way, with six athletes still in medal contention.
Australia's Nicola Olyslagers, who completed her jump before the rain delay, is the only person to clear 2m so far, doing so at the first attempt.
However, the men's discus final is yet to restart.
Men's decathlon final
The final event in the men's decathlon - the 1500m - gets under way at 12:49.
Germany's Leo Neugebauer leads the way with 8072 points. USA's Kyle Garland (8057 points) and Puerto Rico's Ayden Owens-Delerme (7958 points) in the other medal positions.
Women's 4x100m final
One of the greatest competitors in modern athletics, Shelly-Ann Fraser-Pryce, has been confirmed as running the first leg for Jamaica in the women's 4x100m.
This will be Fraser-Pryce's final race before retirement.
For GB, as expected, 200m silver medallist Amy Hunt will run the second leg in place of Success Eduan, who ran in the heats.
Hunt will join Dina Asher-Smith, Desiree Henry and Daryll Neita for the final at 13.10 BST - in Britain's final chance for gold at these championships.

It seems people reading this blog think that the Team GB athletes should be immune to criticism. This has been an underwhelming world championships and that is fact. Improvement is vastly needed ahead of Beijing 2027 and LA 2028

It's hard to know what to say about this Team GB performance. Paris was poor and this was worse. I guess the only way is up?

Women's 4x400m final
It's a championship record for USA, winning the women's 4x400m in 3:16.61. Sydney McClaughlin-Levrone coasted home on the anchor leg. The Olympic champions are back on top of the world!
Jamaica and defending champions Netherlands take silver and bronze, with both teams running season's best times.

Heading into the final lap, USA are still in first place. Gold is looking very secure.
Jamaica are second but the Netherlands' Femke Bol is chasing them down.
