Rui crosses the line first with Li a couple of minutes behind her, Italy's Eleonora Giorgi wins a well-earned bronze.
And that's it for Day 2!
Hope you've enjoyed our live blog, come back for Day 3 tomorrow.
Night!
3:49am - Suzuki wins dramatic 50km walk race
He stopped a few times, dowsed himself in water and just kept going, Yusuke Suzuki is the first ever Japanese man to win a world race walking title less than a year from Tokyo 2020.
It's silver for 43 year-old Joao Viera and Evan Dunfee earns a hard-won bronze, Canada's first medal at a world champs.
2:30am - Cati McCatface!
There you are1
We found this beautiful creature yesterday morning at the marathon and asked our Insta followers to come up with a name, they came through in fine style.
Meet Cati McCatface.
1:50am - Women's walk race: China leads the way
Liang Rui and Li Maocuo are setting the pace halfway through the women's race, but Georgi and Henriques aren't a million miles away, 37 and 40 seconds back respectively.
1:30am - Defending champ Diniz is out!
Suzuki goes it solo as Diniz has dropped out, the Japanese speed-walker looks gold-bound, three minutes clear of nearest rival at the halfway mark.
Diniz had dropped out meaning that Ecuador's Claudio Villanueva is closest to the leader in a three-strong chasing pack, but something dramatic will have to happen to stop Suzuki claiming the top plinth.
12:38pm - Women's 50k walk race: Pack of four
Maocuo Li, the favourite in many experts' minds lead for much of the race so far but it's really tight at the 10k mark, four women in the lead pack are Liang Rui, Eleonora Giorgi, Li and defending champion Ines Henriques.
12:23am - Suzuki speeds ahead
In the men's race Japan's Yosuke Suzuki, the 20km world record holder, leads from France's Yohan Diniz - the defending champion and 50km world record holder.
Olympic champion Matej Toth from Slovakia is third.
Suzuki led by 15 seconds from the chasing pack at one point, but Diniz was having none of that, he's caught up with his rival and that should be a real tussle right to the finish line.
11:09pm - Live bloggers feel your pain Kris!
Hashtag media solidarity.
11:02pm - Think Teshawn enjoyed that Coleman 100m!
10:45pm - Two medals still to come
But that's not all folks, there are still two gold medals ripe for a winning at the world champs.
We're going to hit the road again in the men's and women's 50km race walk finals in and hour and 45 minutes, start time 11:30pm in Doha.
The man who suffered a terrible fate, passing out at Rio 2016 Yohann Diniz is favourite in Doha, while the one to beat in the women's race is China's Li Maocuo.
Set that reminder!
10:23pm - Coleman in pole position for Tokyo 2020
He handled the pressure, he used the anger and frustration about his pre-Worlds drug tests controversy in a positive way and Coleman has confirmed that he's the 100m leading light and favourite to take Usain Bolt's Olympic title.
His 9.76s world beating time in Doha is the 6th fastest 100m in history.
The way he took off and streaked away in the final 10 was reminiscent of Bolt, there's no doubt who the fastest man in the world is right now.
Bring on Tokyo.
10:18pm - Coleman is world champion!
9.76 seconds!
He's untouchable.
Christian Coleman is the new champion of the world!
Defending champ Justin Gatlin takes silver in 9.89, Andre de Grasse is back on the podium in 9.90.
10:08pm - Men's 100m final up next
Christian Coleman's to lose?
De Grasse, Gatlin, Simbine, can anyone stop Coleman?
We're about to find out...
Coleman starts in lane 4 next to Gatlin in lane 3, Simbine in 5, De Grasse in 6, Zharnel Hughes in 7, Blake in 8, Aaron Brown in 9.
The spectacular light show is on, the runners are getting their names in lights on the track, here we go!
10:01pm - Tajay Gayle is world champion!
Who saw this coming?
It's gold for Jamaica's Tajay Gayle who rises to the occasion, springing a big surprise in the men's long jump.
A red flag for Echevarria on his final jump guaranteed the 23-year-old Jamaican his first ever world title.
You can see the disappointment on Echevarria's face, he catches a Cuban flag and drapes it around himself half-heartedly, he's gutted.
So it's silver for Henderson, bronze for Echevarria.
Nothing disciplines you like defeat, let's see if the Cuban prodigy can use this and learn before his first Olympics at Tokyo 2020.
9:49pm - Air Jamaica cleared for take-off
Whoosh!
Tajay Gayle jumps en enormous 8.69 metres!
That's the 10th furthest jump in history, Gayle is ahead of Echevarria on the world all-time list now.
The Cuban can only go 7.91 in his 5th jump, he'll have to do something very special on his final jump, he's currently 3rd behind Olympic champ Henderson.
But Echevarria has gone 8.92 this year (albeit wind assisted), does he have that one big jump left in him?
9:38pm - 10,000m: Sifan Hassan is pure gold!
Ethiopia's Letensebet Gidey took the lead from Hellen Obiri, but Sifan Hassan takes off at the bell!
She's away and gone.
That's the first ever world title for the Dutch runner, finishing in 30:17.62, what a talent she is.
That's a world leading time.
Gidey put her heart and soul into that race, but Hassan saved up all that fire for the last lap, it's a well-earned silver for the Ethiopian.
Kenya's Obiri bags bronze.
9:31pm - Cati McCatface?
We found this cute cat at the marathon last night, and asked for names on Instagram: Catar or Cati McCatface?
Get your vote in!
9:18pm - Long Jump: Trailing Gayle
Gayle launched himself into the lead with his first jump, but he's seen red flags on the next two.
His 8.46 is still the distance to beat.
Echevarria is up... That looks good, the Cuban rarely goes over the line, his first jump was -25cm in the good, and that one gets a white flag too.
That's his best yet, 8.34m, he goes into second behind Henderson.
But Henderson goes 8.39! Manyongo jumps 8.18, he's in fourth.
3 jumps each to come.
9:10pm - Bang! And off goes the Women's 10,000m
The Ethiopians are bouncing in the crowd as the gun goes.
Remember World and Olympic champion Almaz Ayana is not here, so a new world champ will be crowned.
26-year-old Ethiopian-born Dutch runner Sifan Hassan, Rio 2016 5000m silver medallist Hellen Obiri, Kenyan trial champ Agnes Tirop, and Ethiopia’s Letesenbet Gidey are ones to watch here.
9pm - Long jump: Tajay Gayle flies to 8.46m!
It's a lifetime best for Jamaican Tajay Gayle who leaps 8.46 on his first attempt!
Rubs hands excitedly.
This is going be good.
Jeff Henderson's first jump measures in at 8.28m, ahead of favourite Juan Miguel Echevarria's 8.25m.
The Cuban will have to bring his A-Game if he wants that first world title.
8:44pm: Price wins USA's first hammer world title!
Tears and cheers as DeAnna Price wins the USA's first ever hammer throw gold medal.
Her 77.54m throw is the winning distance.
She's wrapped in the stars and stripes, tears flowing, "I love you" she says to her coach and husband J.C. Lambert, locked in a huge embrace.
Beautiful moment.
That's also the maiden gold medal for the U.S. at Doha 2019.
Poland's Joanna Fiodorow wins silver and China's Wang Zheng completes the podium.
8:32pm - First world record!
Ok, it's the first ever race of its kind, but we've watched history in the making in the 4x100m mixed relays.
Fun to watch.
The U.S. records the fastest time of 3:12.42, which goes down as a world record, we'll probably see that broken later this evening.
Jamaica, Bahrain, and Great Britain & Northern Ireland qualified behind USA, and in Heat 2 Poland, Brazil, India and Belgium made the final too.
8:09pm - Pole Vault: Mondo makes it - just
It came down to his final jump but European champion Armand 'Mondo' Duplantis clears 5.75m at the third attempt, making sure of his place in the final.
He blows put his cheeks and lies back on the mat.
Phew emoji.
Germany's Raphael Holzdeppe also makes at the third attempt to secure his spot in Tuesday's final, and he celebrates like he's won it! Not sure if there's an emoji for that one.
Sam Kendricks, Thiago Braz, Claudio Michel Stecchi, and China's 23-year-old Bokai Huang (Who jumped a personal best 5.75) all progress from Group A.
Group B qualifiers include Piotr Lisek, Cole Walsh, Mondo and Holzdeppe.
8pm - Price leads Hammer final
Leading with a 76.87m throw, DeAnna Price does even better throwing 77.54m, she's delighted with that.
The U.S. has never won this event and Price is bidding to break new ground.
Closest to Price right now is Poland's Joanna Fiodorow who spun a 76.35 personal best on her first attempt.
7:48pm - Move! Haliham Nakaayi coming through
Huge smiles for Uganda's Haliham Nakaayi as she wins the final 800m semi in 1:59.35.
Eunice Sum and Natoya Goule were in her way with 100m to go so she just barged her way through, Goule particularly put off-balance, and the Jamaican can only finish fourth.
The first two qualify...
The judges will probably take a look at that.
But it may not matter as Goule qualifies anyway with her time, USA runner Ce'Aira Brown took third and she's in the final too.
7:42pm - An hour before Echevarria takes flight
An hour to go before the long jump final, Echevarria to leap to a first world title?
Stay tuned!
7:36pm - Men's 100m finalists
Here's the confirmation of the 100m finalists:
7:26pm - Ajee Wilson bosses semi-final
It's a slow start in Heat 2 with Wilson setting the pace, she takes it and there's a real battle for the second qualifying spot.
Almanza, Arafi, and Oskan-Clarke all fighting, but it's the Moroccan who comes through.
Rababe Arafi qualifies with Wilson in a slow heat dictated by Ajee Wilson, that really suited her, plenty left in the tank.
Times:
- Ajee Wilson 2.00.31
- Rababe Arafi 2.00.80
7:22pm - Pole vault update
Olympic champion Thiago Braz, defending world champion Sam Kendricks, European champion Mondo Duplantis, and two-time 2019 six-metre jumper Piotr Lisek all have a clean slate so far.
The automatic qualification mark is 4.75m, they're currently jumping 4.70 and it's the big names delivering so far.
7:15pm - Women's 800m semi-finals
The gun goes on the Heat 1, U.S. runner Raevyn Rogers is the name that stands out here, and she goes straight into the lead.
Winnie Nanyondo from Uganda is pushing her on the inside but Rogers closes the door.
And that's how it finishes, Rogers pushed the pace, Nanyondo stayed with her, they left everyone else behind.
1:59.57 is the winning time.
7:03pm - Heat 3: Sambini and Hughes through
Consistency from South African Akani Sambini who wins the third and final semi-final heat in 10.01, terrible start from European champ Zharnel Hughes but does well to recover, finishing in 10.05.
Justin Gatlin and Italian Filippo Tortu qualify for the final with fastest times outside the top two.
6:52pm - Heat 2: Gatlin-Blake-De Grasse
Heat 2 features reigning world champion Justin Gatlin, former world champion Johan Blake, and Rio 100m bronze medallist Andre De Grasse.
And De Grasse takes it!
Laid low by a hamstring injury, De Grasse is back, he stole through as Gatlin and Blake were focused on each other, that was close - so close they finish on the same time! 10.09
Gatlin should qualify as a fastest loser.
It finished:
- Andre De Grasse 10.07
- Johan Blake 10.09
- Justin Gatlin 10.09
6:48pm - Christian Coleman goes 9.88!
Boom.
Explodes off the blocks, streaks away from the very start, blitzes race, runs straight down the tunnel.
Coleman drops a searing semi-final.
That's not far off his 9.81 season's best, 9.79 is his PB.
Aaron Brown is second on 10.12 and Adam Gemeli third on 10.13.
6:42pm - Big three through in 400m hurdles
Karsten Warholm was on cruise control in his semi-final, winning at a canter, while Rai Benjamin won Heat 3 with Abderrahman Samba just behind him.
Warholm to slay the world record? Samba or Benjamin to stun the Norwegian?
Thiere will be fireworks in that final.
100m up next!
6:34pm - Korir speaks to Olympic Channel
Emmanuel Korir, the fastest qualifier for the semis for the men's 800m spoke to us about the late withdrawal of Nijel Amos:, and how he's just happy to be here after a serious car accident 2 months ago in Eldoret, Kenya:
"It's bad. Amos is a great athlete and competitor. It all depends with what he was expecting to do. I can’t say how it would have been in the final."
He also talked about his season so far and stepping into David Rudisha's shoes as king of 800m in Kenya.
"I’ve had a lot of injuries this season, a stress fracture and a shoulder dislocation. Then the car accident , I thank God I am alive and I’m here, because it was bad."
- Emannuel Korir to Olympic Channel
Korir has one eye on Tokyo 2020 already:
"To qualify for the Diamond League finals and World Championships is great, but my main focus for now is next year."
6:25pm - Korir clocks fastest 800m
That was fast.
Emmanuel Korir clocks the quickest men's 800m qualifying time in 1:45.16.
Mostafa Smaili and Wesley Vazquez qualify in 2nd and 3rd.
Elliot Giles wins the final 800m heat in 1:45.53 taking over after 500m, Clayton Murphy claimed second and Amel Tuka is third.
6:17pm - 800m heats
Defending champ Pierre-Ambroise Bosse was forced to run a faster race than he might have liked by Qatar's Abubaker Haydar Abdalla who wanted to put on a show in front of home fans.
Brandon McBride pipped it at the line, Bosse and Abdalla completing the automatic spots.
Heat four brings a surprise as it goes right down to the wire despite the presence of Adam Kzszcot five runners have a chance at the line:
Ferguson Cherutiot Rotich, Bryce Hoppel and Ayouni take the top three places, and Kszczot can only finish fifth.
He'll have to wait and see if he goes through as a fastest loser.
6:05pm - Breaking: Divine Oduduru out of Worlds
Reigning NCAA champion Divine Oduduru is not listed in Sunday’s 200m heats meaning that his World Championships is over.
He withdrew from the 100m yesterday to focus on the 200m, but it looks like he withdrew after the final confirmation stage which disqualifies him from the rest of his events.
Devastating from a man the world expected so much from in Doha.
Olympic Channel's Evelyn Watta is on the ground trying to confirm exactly what happened.
5:56pm - Kipngetich tops heat 2
In the heat that Nijel Amos should have been Kenya's Ngeno Kipngetich and Adrian Ben of Spain open up down the home straight coming in at blistering pace.
GBR's Jamie Webb holds on to third and that last automatic qualifying place.
5:51pm - Making plans for Nijel
It's making plans without Nijel at the Doha Worlds, Nijel Amos had to drop out of the second heat with the word going around the stadium that an Achilles' injury flared up when he was warming up.
The Botswanan and his many fans at home will be very disappointed.
Get better soon Nijel!
5:43pm - Fraser-Pryce brings the sunshine
We caught up with Shelly-Ann Fraser-Pryce who ran 10.80s earlier - the fastest 100m heat in IAAF World Championships history:
"For me, it felt good to execute and making sure that I get to the next round because that has always been the aim at these championships. The heat doesn’t really matter. It’s about the finals and getting to the finals."
That 10.80 came with her hardy even trying.
"It’s just progress as easily as possible through each round. And I was glad that I was able to do that."
What about the yellow hair?
"The hair? it is like sunshine. Jamaica is hot, Doha is hot, so I decided to go for yellow!" - Shelly Ann Fraser-Pryce
5:37pm - Men's discus qualification
Group A has finished up in the men's discus with no-one making the automatic mark, Jamaica's Federick Dacres came closest with 65.44m.
The top four or five should make it through, Group B is up next.
5:22pm - Brazier takes Men's 800m Heat 1
Remember, the first three qualify from the 800m, USA's Donovan Brazier takes the first heat finding that extra gear in the final 50m winning heat 1 in 1:46.04.
Canada's Marco Arop and Swede Andrea Kramer led for much of the race, but Brozier turned on the turbo on the curve.
Arop is second, Tshepo Tshite from South Africa overtook Kramer who tired in the closing 30 metres to grab the third auto qualifier spot.
Big news for Brozier as it looks like the favourite is out:
5:15pm - Four fastest women today:
5:05pm - Dafne Schippers takes final heat
Flying DutchwomanDafne Schippers wins that heat with a powerful finish making up for an awful start, she clocks 11.17.
She's two-time reigning world 200m champion, and needed the distance to turn that one around.
Teahna Daniels and Gina Bass qualify in second and third.
4:58pm - Tori Bowie up next
Heat 5 of 6 next, look out for the U.S. sprinter Tori Bowie...
But that's a really poor start, ragged by her standards, and she can only finish third.
Mujinga Kambudji tops heat five in 11.17, and that's a great run from China's Liang Xiaojing who exploded off the blocks too.
Liang clocked 11.18, Bowie 11.30.
4:53pm - Asher-Smith in great shape
That's a really solid run from Britain's 100m hope.
10.96 for Dina Asher-Smith, great technique, ran tight all the way through, little look around to see she's clear a few metres from the pack.
USA's English Gardner and Jamaica's Joneille Smith finish on exactly the same time: 11.20s
4:47pm - Thompson clocks 11.14s
Elaine Thompson has a slow start and has to work a little to win that heat.
She didn't really get started at all there, Kelly-Ann Baptiste was right on her shoulder finishing in 11.21s, USA's Morolake Akinosun is third.
Dutee Chand places 7th finishing in 11.48 seconds.
4:42pm - Elaine Thompson's response?
Rio 2016 100 and 200m champ Elaine Thompson is up next in heat 3.
We've seen two lightning heats already, can Thompson top it?
India's Dutee Chand is also in action here.
Not the best race ever from Thompson, has to work to win.
4:36pm - Ta Lou up next
African Games champion Marie-Josee Ta Lou from the Ivory Coast should dominate this next heat.
Ta Lou streaks away: 10.85
So exciting to watch, that cadence, pumping those legs, she's finishes way ahead of Britain's Daryll Neita who clocks 11.12.
"I haven't run that fast since 2017 says Neita, I'm really happy."
4:31pm - Shelly Ann Fraser-Pryce goes 10.81s!
Wow.
Shelly Ann Fraser-Pryce makes a strong opening statement beyond her brilliant yellow hair.
Pure power, and she even pulled up towards the end.
That's different class, not far off her 10.73 season's best this year.
4:23pm - The fastest woman in the world?
The women's 100m gets underway today.
We'll see Olympic champions Elaine Thompson and Shelly-Ann Fraser Pryce who head the world rankings this year with 10.73s, just three-hundredths of a second outside their respective personal bests.
But Britain's Dina Asher-Smith could announce her Olympic intentions by challenging the Jamaicans here in Qatar.
Add African Games champion Marie-Josee Ta Lou, two-time reigning world 200m champion Dafne Schippers and three members of USA's victorious 4x100m relay team at Rio 2016 to the mix and today is going to be fun.
Here's a full preview of the women's 100m event.
4:11pm - Day 2 Schedule
Here's the full rundown of what's happening today:
3:39pm - Day 2 is on!
Usain Bolt's Empire of Sprint © is over and his successors have aligned in Doha, with Christian Coleman, defending world champ Justin Gatlin, and South Africa's Akani Simbine looking keen on his crown.
We'll find out tonight who wins the 100m Game of Thrones, semi-finals at 6:45pm, and the final is at 9:15pm in Doha.
Will Echevarria win his first world title? Long jump final is at 8:40pm.
The fastest women in the world will sprint off over 100m in the heats today, that's at 4:30pm, and the first ever 4x400m mixed relay may give us a glimpse at the most decorated women's U.S. track ever: Allyson Felix.
3:08pm - We're live!
Day 1 opened with pyrotechnics on and off the track, including Christian Coleman running the only sub-10 second 100m heat, Juan Miguel Echevarria jumped 8.40m on his first jump, way beyond anyone else, and Ruth Chepngetich won the first ever IAAF World Championships midnight marathon.
Find out how it all went down here.
What to get excited about on Day 2
Day 1 will crown the fastest man alive in the men's 100m: the race the world stops to watch.
Once upon a time there was a sprinter named Usain Bolt who lit it up, you may have heard of him, but for the first time since Saint-Denis 2003 he ain't here.
It's time for a new king and the principle pretender to to the throne is Christian Coleman, who put the drug test controversy behind him to run the only sub-10 heat yesterday: 9.98
But there are plenty of other names who want to wear the crown: 37-year-old Gatlin proved he was fit yesterday, South Africa's Akani Simbine ran 10.02 in his heat, and Andre De Grasse, Hakim Sani Brown and Yohan Blake will all plotting their path to the top of the podium.
Here's the full schedule of today's action:
Who can stop Echevarria?
Cuba's long jump superhero Juan Miguel Echevarria jumped 25cms further than anyone else in qualifying yesterday jumping 8.40m making him the man to beat in today's final.
The charismatic Cuban won the Pan American Games in August and wants to write his name among the world champions less than a year off the Tokyo 2020 Olympics.
The closest to the high-flying Echevarria yesterday was Japan's Shontaro Shiroyama, but with the reigning Olympic champion Jeff Henderson and the defending world champ Luvo Manyonga in the field, Cuba's would-be world-beater can take nothing for granted.
Women's 800m semi-finals
In the absence of Caster Semenya due to the new IAAF DSD regulations, we're going to have a new 800m champion.
We'll have the semi-finals today at 7:15pm, with the final on Day 4, Monday.
In the absence of Semenya, Ajee Wilson, Raevyn Rogers and Natoya Goule are the names that sound most likely to be in the same sentence as world champion on Monday.
Women's 10,000m Preview
In the absence of World and Olympic champion Almaz Ayana who is still recovering double knee surgery in July last year, it's a fascinating field.
Ethiopian-born Dutch runner Sifan Hassan is a serious contender, at 26 what she lacks in experience she more than makes for in talent and courage.
Hassan has really backed herself in Doha entering the 10,000m, the 5000m and the 1500m.
Could she win all three?
Unlikely, she'll drop one of the shorter distances after tomorrow's 10,000m, by which time she may already be wearing a gold medal.
Rio 2016 5000m silver medallist Hellen Obiri may have something to say about that, Agnes Tirop, who outlasted Obiri in the Kenyan trial, or Ethiopia’s Letesenbet Gidey will also be keen to change the conversation.
The Price is right
USA's DeAnna Price dominated the qualifying round in the women’s hammer with 73.77m and will go all-out to make that gold medal hers in the final.
Men's pole vault
Saturday also brings the men's pole vault qualifiers, we're excited to see the next generation bring the sport to new heights.
