9:59pm - BREAKING: Jamaica disqualified from 4x400m
News just in that Jamaica has been disqualified from that women's 4x400m relay final.
That means that Britain climbs up onto the podium behind Poland.
9:38pm - Rai Benjamin takes it home - Gold for the USA!
It's a 400m sweep for the United States, Rai Benjamin took it home with some to spare.
Jamaica are close(ish) at the the third exchange but the London-Benjamin handover is really clean and there's no stopping Benjamin.
Gold for the USA, silver for Jamaica whose challenge to the champions never really materialised, and Belgium held on for bronze with Colombia's Zambrano left with too much to do.
Here's how it ended:
- USA 2:56.59 (World leading time this year)
- Jamaica 2:57.90 (SB)
- Belgium 2:58.78 (SB)
That's the USA's 14th gold medal at Doha 2019, the strength in depth on show once more less than a year away from the Tokyo 2020 Olympics.
9:29pm - Men's 4x400m relay
Drum roll... And our final event of Doha 2019 is next - hit the lights.
Plenty of bright lights in the U.S. line-up for the men's relay:
1. Fred KERLEY
2. Michael CHERRY
3. Wilbert LONDON
4. Rai BENJAMIN
Jamaica should give them a run for their money:
1. Akeem BLOOMFIELD
2. Nathon ALLEN
3. Terry Ricardo THOMAS
4. Demish GAYE
Trinidad and Tobago are defending champions after they stunned the U.S. in 2017:
1. Asa GUEVARA
2. Jereem RICHARDS
3. Deon LENDORE
4. Machel CEDENIO
Look out for Colombia to challenge for a podium place, the Pan Am champs have the fastest finisher in the business:
1. Jhon Alejandro PERLAZA
2. Diego PALOMEQUE
3. Jhon Alexander SOLIS
4. Anthony José ZAMBRANO
9:31pm - U.S.A. G.O.A.T.
The USA will be awarded eight gold medals as they changed the entire line-up for that final.
That means that Allyson Felix will be awarded her 13th Worlds gold medal of her career.
U.S.A. G.O.A.T.
9:19pm - USA win 400m relay gold, Poland second!
Phyllis Francis with a seriously fast start, Sydney McLaughlin kept that lead, when 400m silver medallist McLaughlin handed over to world champion Dalilah Muhammad the U.S. were already away and gone and sure of their gold medal.
It was a poor start from Jamaica, but they recovered and were closest to the U.S. closing in at the finish, only for Poland to pip it at the line.
Justyna Swiety-Ersetic ran a serious final 400m for Poland, overtaking Jamaica's Shericka Jackson to win silver for Poland, great run from the Poles.
GB finish fourth just outside the medals.
9:17pm - Women's 4x400m hurdles final
The lights go down, the noise goes up for the 4x400m final.
USA and Jamaica the two favourites but there are lots of changes including all four from the U.S.
Jamaica ran 3:24.64 yesterday setting a new world leading time, until the USA's fab four reset in in their heat: 2: 3:22.96.
Rio silver medallist Stephenie Ann McPherson anchored Jamaica without having to really work meaning she should be fresh today.
Felix, who's already claimed her 12th world champs medal (More than Bolt!) by winning the mixed relay, is part of a team that looks individually in form and collectively in sync.
It will take something extraordinary to beat them.
Great Britain finished two seconds behind the USA and look likely for a podium finish, Poland could challenge for a medal too, as could a Sage Watson-led Canada.
Watson won gold in the 400m hurdles and was crucial to Canada's silver medal performance at Lima 2019.
9:12pm - Gold for Grenada!
21-year-old Anderson Peters is champion of the world!
He's flying the flag, the winning mark was 86.89.
Magnus Kirt picks up silver despite being stretchered off, his 86.21 is worth its weight in silver.
Germany's Johannes Vetter claims bronze, 85.37 is his best of the night.
This looks an open and exciting field before Tokyo 2020.
9:05pm - Men's javelin: Kirt stretchered off!
It looked like Magnus Kirt dislocated his shoulder there, he's down and calling for a stretcher, it's all over for the Estonian.
That means the leader Anderson Peters looks even more likely to win Grenada's first medal of the Worlds - and it should be gold too.
That would make it 41 nations on the medal table.
8:53pm - Nia Ali is women's 100m H world champion!
It's Ali's world title after coming back from having her second child!
A personal best 12.34 gives Ali gold.
And it's a first Worlds medal of any colour for Keni Harrison who makes it a USA 1-2, that must be sweet after everything that she's been through between false starts and hitting hurdles and failing in U.S. trials.
12.46 is Harrison's time.
Jamaica bag bronze through Danielle Williams who didn't run her best race, misjudging the 3rd last barrier and never really recovering.
12.47s from Williams.
Megan Tapper crashed out early too.
8:47pm - Mihambo wins the women's long jump
Malaika Mihambo came in with a great weight of expectation in this final, and she's dealt with it so well.
A slow start was obliterated by a 7.30m leap in her third attempt, no-one could come close.
That's Germany's second gold medal of Doha 2019.
Ukraine's Maryna Bekh-Maranchuk wins silver with a 6.92m mark and it's silver for Nigeria's Ese Brume clearing 6.91m.
8:40pm - Anderson Peters leads javelin final
Grenada's Peters still out in front with that 86.69m first attempt, but Kirt and Vetter have three attempts to come.
8:31pm - Men's 10,000m final: Gold for Cheptegei!
The Ugandan kicks at the bell, Kejelcha goes with him, but it's world cross country winner Cheptegei who takes on the world and wins!
Gold for 23-year-old Joshua Cheptegei.
He's just off the championship record, that's the second fastest 10,000m ever: 26:48.36
Delight for the Ugandans who are dancing in the stands.
And it's a next-gen podium with 22-year-old Yomif Kejelcha in second and 19-year-old Rhonex Kipruto winning bronze.
Kejelcha clocked 26:49.34 and Kipruto 26:50.32.
A flying final sees an all-African podium.
8:25pm - 10,000m final: Cheptegei out front
The lead pack has lost a numbers of finalists with this brutal pace, Cheptegei and the two Kenyans are leading the way, forcing the pace.
Kipruto surges to the top again, and he should be tired as he's been the most surgey of all but he looks so fresh, so calm.
Three laps to go.
8:21pm - Better from Vetter
Back at the spear-throwing it's a javelin superman throw that leaves Vetter flat out on the ground, putting his whole body into that hurl.
85.37 - that puts him straight into second place.
But up steps Kirt and he spins a perfectly shaped throw out 85.37 metres.
Kirt second, Vetter third.
8:13pm - Men's 10,000m final: Kipruto breaks, then brakes
Bemused glances as one of the podium likelies Rhonex Kipruto makes a break and ups the speed to somwhere most runners simply don't want to go.
The Kenyan has a look around and says 'who's next?'
Cheptegei steps up with 16 laps to go.
But Kipruto can't help himself! He's joined by Kwemoi at the front and they're keeping this quick
Ethiopians Yomif Kejelcha and Belihu Hagos, are right there, as is Gebrhiwet and Uganda's Cheptegei.
Kipruto leads at halfway.
8:04pm - Javelin final launched
2012 Olympic champion Keshorn Walcott does the launching, spearing it out to 75.30m.
The Trinidadian is quickly overtaken though, a giant hurl from Grenada's Anderson Peters - 86.69 for the lead.
Magnus Kirt and defending champ Johannes Vetter among the big names in this final, Kirt flings a 83.95 and Vetter is flagged red on his first attempt.
Calibrating.
7:58pm - Women's high jump: 7.30m from Mihambo!
Back over in the sand, the German puts the pressure of the favourite tag aside and takes flight, that's huge!
7 metres 30!
That's the twelfth biggest jump of all time.
Surely that's gold already, and she has three more attempts to go.
Ese Brume drops to second and Ukraine's Maryna Bekh-Maranchuk is third on 6.91m.
7:44pm - Golden Cheruiyot takes 1500m final
A really early move from Cheruiyot, has he gone too soon?
Here comes the finish - the world No.1 this year Cheruiyot takes it!
Gold for the Kenyan in 3:29.26.
Algeria's Taoufik Makhloufi was never going to overtake Cheruiyot, a season's best 3:31.38 gives him silver, that's a fantastic finish for him.
An equally impressive bronze for Marcin Lewankowski who clocks 3:31.46 - a new national record.
Jakob Ingebrigtsen finishes just off the podium in 3:31.70, the race began quite slow which suited the Norwegian, but when Cheruiyot upped the pace significantly the 19-year-old just didn't have that necessary extra in the finish.
He'll have learned a lot from that.
There were three Scots in that race, and two of them finished in fifth and sixth, great racing from Jake Wightman and Josh Kerr.
7:38pm - Women's high jump final is on!
The best of the world's high-flying elite steps on the runway, they'll have six attempts each to win a world title.
Not the best of starts for Malaika Mihambo who goes 6.52 in her first jump and X's her second.
Brittany Reese crashed out yesterday unexpectedly making the favourite German Mihambo even more favourite.
Nigerian Ese Brume leads for now on a 6.91m leap, but there's a long way to go.
7:21pm - Nigerian Amusan aces Heat 3
Another impressive run from Nigerian Tobi Amusan with that fluid style and natural rhythm of hers, running another clean 100m - she set a PB 12.48 yesterday and matches it in this heat today.
She's Commonwealth Games, African Championships and African Games champion, can she take the step up to the world podium in an hour and a half?
She's given herself every opportunity.
Janeek Brown is second in 12.62, that means we'll have four Jamaicans in the final.
Costa Rica's Andrea Carolina Vargas was so happy to make it into the semis yesterday and today she makes the final!
It's a national record too, delight for Vargas.
Can Amusan break into that big three of Williams, Ali and Harrison?
As we saw in the men's final with Omar McLeod crashing out and taking Orlando Ortega with him, anything can happen in a hurdles final.
7:16pm - Women's 100m H semi: Keni tops Heat 2
Keni Harrison tops that slightly slower heat in 12:58, moving well.
The world record holder wants that first world outdoor title here in Doha.
Two Jamaicans in second and third: Megan Tapper and Yanique Thompson went 12:61 and 12:80.
7:08pm - Women's 100m H semi-finals
It's Danielle Williams and Nia Ali neck and neck, Williams takes it... Clocking 12.41
Just.
The two big favourites came up big in Heat 1, Ali finishing second in 12.44, a PB for the U.S. hurdler.
World leader Williams won that on the final few hurdles and Ali - who's just returned from having her second child - are both very much in contention for that final later.
Nadine Visser had a very strong start but lost the leaders in the finish, she sets a new Dutch record: 12.62.
6:48pm - Going the distance: 10,000m and 1500m finals
We're really looking forward to these two races tonight, Timothy Cheruiyot is favourite in the 1500, but Norwegian sensation Jakob Ingebrigtsen (Still only 19!), Marcin Lewandowski and the Swedish surprise Kalle Berglund all looked good in the semis.
In the 10,000m Mo is no mo', and with the exit of Farah to focus on the marathon, we'll have a new champion today for the first time since 2013.
Silver medallist at London 2017 Joshua Cheptegei maybe slight favourite to step up on the podium, but he'll have to contend with the considerable talents of Yomif Kejelcha, Hagos Gebrhiwet and Rhonex Kipruto.
It's anyone's game.
6:36pm - More trouble tonight
"When we're on the same team, that means trouble for the rest of the world!"
Christian Coleman stopped for a chat after the USA's spectacular 4x100m relay gold medal run last night, the USA can add to their relay tally tonight in both the men's and women's 400m relays.
6:24pm - Double delight for Ethiopian fans
Lelisa Desisa got the party started early this morning winning the first ever men's IAAF World Championships midnight marathon.
And it was double the celebrations with another Ethiopian securing second: Mosinet Geremew
There are many Ethiopians living and working in Doha and their celebrations at the finish line were something special:
6:20pm - Today's Schedule
The World Championships is ready to bow out in style today, here's how Doha 2019 plans to go down in a blaze of glory:
Women's 100m hurdles final
Fraser-Pryce, Allyson Felix, Liu Hong, Nia Ali?
Women winning gold medals who have returned after giving birth has become a bit of a theme here at the world championships, is Nia Ali next?
Olympic silver medallist Ali is back on track after a year off where she had her second child with Canadian sprinter Andre De Grasse.
She won Heat 1 comfortably in 12.59 yesterday.
Ali will have to contend with 2015 champion Danielle Williams who put down the fastest qualifier yesterday: 12.51
She stunned the world four years ago, but it would be no surprise to see Williams top the podium this time around.
The third gold medal contender is world record holder Keni Harrison.
Her calmness and composure caught the eye yesterday winning her heat in 12.55.
It was disaster for the reigning Olympic champion Brianna McNeal after she crashed out with her fourth false start of this season yesterday.
A personal best from Nigeria's Tobi Amusan puts her among the podium contenders too, can she add to those gold medals at the Commonwealth Games, African Championships and African Games?
Amusan clocked the fastest qualifying time across all the heats: 12.48 (A new PB).
We'll see the semi-finals first up on Day 10.
Women's long jump final
Next on the menu is a world championship that looks Germany bound: Malaika Mihambo is just making winning look so easy.
Mihambo came into these Worlds on the back of a nine competition winning streak, clearing seven metres in five of those – six if you include her wind-aided 7.11m (2.2m/s) victory at the European Team Championships.
She topped her qualifier with a 6.98m jump yesterday, leaving lots in the tank.
The 25-year-old was the only one her group to clear the automatic qualifying distance.
Mihambo will have to hold off the challenge of the multi-talented Tori Bowie who won a gold, silver, and bronze medal at Rio 2016, but all in sprint events.
Can Bowie add a Worlds long jump gold medal to her collection of precious metals?
A 6:77m jump yesterday bodes well.
Brittany Reese was one who analysts saw as a potential nemesis for Germany's top jumper, but Reese failed to qualify from Group A, making 2018 European champion Mihambo even more likely to become 2019 world champion.
The Ukraine's Maryna Bekh-Romanchuk came closest to Mihambo in the other group, jumping 6.74m.
Behind her Abigail Irozuru, Nastassia Mironchyk-Ivanova and Jamaica's Sha'keela Saunders all went through to tomorrow's final.
But it's Mihambo leads the world with 7.16m, owns the three best jumps in the world this season, five of the best six, and six of the best eight.
Can anyone outjump her in the final?
Men's javelin
Magnus Kirt is having the season of a lifetime.
Mr. Consistency set a national record of 90.34m in Ostrava, then reset it - 90.61m - in Kuortane, a world leading throw.
Yesterday the Estonian launched the javelin 88.36 to win his group.
Kirt also won silver in the Diamond League final in Zurich, and he's on course for a world title here in Doha, but as we've seen already, there are no givens in finals.
There were two shocks yesterday as Rio 2016 champ Thomas Rohler crashed out of the men's javelin competition, then 2018 Diamond League champion Andreas Hoffman headed for the exit too.
Both can throw over 90m on a good day, but Hofmann could only cast the spear 80.06m and Rohler 79.23m.
No such trouble for defending champ Johannes Vetter who threw 89.35 on his first attempt yesterday, and the 21-year-old NCAA and Pan Am champ Anderson Peters from Grenada was only 4cm behind on 85.34.
Peters could easily be a podium finisher today.
Women's 4x400m relay: Jamaica vs. The USA
These sprint titans go head to head once more in the 4x400 relay.
Jamaica ran 3:24.64 yesterday setting a new world leading time, until the USA's fab four reset in in their heat: 2: 3:22.96.
Rio silver medallist Stephenie Ann McPherson anchored Jamaica without having to really work meaning she should be fresh today.
Here's the U.S. line-up:
1. Jessica BEARD
2. Allyson FELIX
3. Kendall ELLIS
4. Courtney OKOLO
Felix, who's already claimed her 12th world champs medal (More than Bolt!) by winning the mixed relay, is part of a team that looks individually in form and collectively in sync.
It will take something extraordinary to beat them.
Great Britain finished two seconds behind the USA and look likely for a podium finish, Poland could challenge for a medal too, as could a Sage Watson-led Canada.
Watson won gold in the 400m hurdles and was crucial to Canada's silver medal performance at Lima 2019.
Men's 4x400m relay final: The USA v Jamaica part 2
In the very last event of Doha 2019 we can expect fireworks in the final final.
The U.S. and Jamaica again come in as favourites, but remember what happened at London 2017?
The USA were favourites in that final too but Trinidad and Tobago stunned the statesiders, Jareem Richards and Machel Cedenio were the heroes for Trinidad that day.
The United States had a couple of shaky handovers yesterday, Vernon Norwood exchange with Wilbert London, cost them the lead in their heat yesterday, but raw power got them out of trouble.
London turned on the turbo, leaving anchor Nathan Strother a long lead to work with, and the USA qualified first in 2:59.89.
Jamaica were less than a second off the USA's time yesterday, anchor Javon Francis brought it home.
Keep an eye on Colombia too, they qualified behind Jamaica, with individual silver medallist Anthony Zambrano finishing like lightning, he's worth the admission alone.
The Pan Am champs Colombia set a new national record: 3:01.06
Defending champs Trinidad and Tobago finished third behind Colombia, who could bring the curtain down on the World Championships 2019 with a big surprise.
