Day 7 brought shocks and surprises as Salwa Eid Naser stunned Shaunae Miller-Uibo and both the heptathlon and decathlon had surprise winners.
The best in the world lit up Doha on Day 7 as we were treated to a night of sensational results.
Scroll down to see what happened!
27 Sep - 6 Oct 2019
2019 IAAF World Championships - Doha
Here's what she told us afterwards:
Niklas Kaul wins the 1500m and Decathlon gold on his senior debut!
The youngest winner at the world championships.
His 4:15.71 gives him the win and gold with 8691 points.
Estonian Maicel Uibo is second, and it's a third world champs medal for Damian Warner.
Much respect for all these athletes in one of the most gruelling disciplines there is.
Katarina Johnson-Thompson is on top of the world!
She wins the race in 2:07.26 and the gold medal with 1005 points in that race, 6981 points overall - a world leading return.
World indoor champion KJT has become world outdoor champion, as Nafi Thiam has to hand over her crown.
KJT is in tears.
She was so close to the coveted 7000 point mark, but that hardly matters.
This is going to be one of the rivalries of the Games at Tokyo 2020.
There's just 15 points between first and second on the decathlon leaderboard after the javelin event, German Niklas Kaul came through in the event he was expected to top.
He stepped on the launchpad and sent a 79.05m throw soaring through the Doha night sky: the furthest anyone has ever thrown a javelin at a world championship.
Almost 17cm beyond Warner in second in Group B who threw 62.87.
But it's Maicel Uibo who leads heading into the final 1500m event on 7869 points, 15 ahead of Warner, 19 ahead of Kaul.
Miller-Uibo or Naser?
Here we go!
Gold for the Bahraini!
Naser took off and never stopped accelerating, it looked like she went too early, but no.
Miller-Uibo tried to reel her in and run her race, clocking the 6th fastest time ever and just manages to win silver.
Naser gives us a glimpse into the future there, that was so fast - the 3rd fastest 400 in history!
That was a much quicker heat, USA's Jenny Simpson is first in 4:00.99, the woman who won gold at Daegu 2011, and two silver medals at Moscow 2013 and London 2017 looks podium-bound again.
Ethiopia's Gudaf Tsegay led with less than a lap to go but faded away, passed Gabriela Debues-Stafford and Laura Muir, who claim second and third.
Tsegay holds on to fourth, Kenya's Winny Chebet takes the final Q on offer.
Winnie Nanyondo and American Nikki Hiltz also make it with quickest qualifying times outside the auto spots.
"Huge disappointment, but no regrets. I gave it my all, and under these conditions I had to accept defeat. Thank you for all your messages, tomorrow begins my return to health and getting to Tokyo at full strength."
Kat Johnson-Thompson's family are ready to celebrate a medal on Merseyside - will it be gold?
10k gold medallist Sifan Hassan takes a fairly pedestrian 1500m, pedestrian for them, not for the rest of us.
Hassan played her cards right there, at the front of the pack as the bell goes, kicks on and wins in 4:14.69.
The always dangerous Shelby Houlihan, Rababe Arafi who ran the 800m, world and Olympic champion Faith Kipyegon from Kenya finish 2nd, 3rd and 4th.
And a great race from Ireland's Ciara Mageean who claims that final automatic spot.
We're underway, China’s Gong Lijao is the defending champion, and she's into the lead with a 19.42 on her second throw.
Only the USA's Chase Ealey has beaten Gong this year, Ealey hurls out an 18.70 on her first cast.
The experienced German Christina Schwanitz is also looking to do some damage, she throws 18.87 on attempt 2.
The one looking most likely to break into that top three is Jamaica's Danniel Thomas-Dodd, who's made her intentions very clear with a 19.02 on her second throw.
This came through a while ago, a happy moment for Orlando Ortega:
The first nine have qualified from that final heat, Djibouti's Ayanleh Souleiman tops it in 3:36.16, the fastest time of the three heats.
The top three are so close, Taoufik Makhloufi is .02 behind the winner, and Sweden's Kalle Berglund .01 behind him.
It's a bit frantic as a big pack jostles for Q's, but they need not, all nine in that finishing pack qualify:
Neil Gourley, Craig Engels, and Ronald Musagala are all through to tomorrow's semi-finals.
Timothy Cheruyiot tops Heat 2 that while looking magnificently composed clocking 3:36.82.
But behind him it was bedlam, Ethiopian Teddese Lemi blocks off Filip Ingebrigtsen and there's some pushing before Ingebrigtsen crosses Lemi's path, clipping hi heels and down he goes!
Ingebrigtsen finishes in an automatic fourth place, along with Josh Kerr, Ben Blankenship, Abdelaati Iguider, and Kevin Lopez.
Lemi has a good chance of being reinstated though, let's see what happens.
Jakob Ingebrigtsen takes first place in Heat 1 in 3:37.67, Ethiopian Samuel Tefera lead at the bell but was swallowed up by a late wave of runners and only finishes fifth.
That was a melee at the line, 0.3 seconds between the top eight finishers.
France's Alexis Miellet is second, Matthew Centrowitz of Team USA third GBR's Jake Wightman fourth, Marcin Lewandowski fifth and Amos Bartelsmeyer sixth.
Remember, six automatic qualification spots in each heat.
Timothy Cheruyiot up in the next heat.
The men's pole vault event concludes and the most dramatic moment was the exit of Kevin Bayer, he'll have to cede that world title, and in his absence it's excitingly open.
There are five men who could still win gold, debutant Niklas Kaul just won Group B of the pole vault and has the best javelin on paper - the next event up.
Could we see a young breakthrough winner?
Warner, LePaige, Uibo, Shkurenyov, all very much in the running too.
Back to shot put as the Group B qualifiers get underway.
Rio 2016 champ Ryan Crouser flies out a 21.67 throw beyond the Q line like he was throwing his keys on the table.
Attempt 1, job done.
Jacko Gill (21.12), Filip Mihaljevic (21.00) and Joe Kovacs (20.92) all join him in the final, the Croatian Mihaljevic was the only one who needed more than one attempt.
Thiam opted not to take her final throw in the javelin event which leaves Kat Johnson-Thompson out in front before one of her favourite events in the 800m.
Can Thiam upset the new British favourite, can Kat bring it home?
We'll see that final in about three hours, 12:05am local time.
Group A qualifiers are in, there were four men who went beyond the automatic qualifying distance with their first throw:
New Zealander Tomas Walsh casts out a 21.92m which is the leading distance, he's the Diamond League champion, Darlan Romani, Konrad Bukowiecki, and 2018 Diamond League champ Darrell Hill.
Armin Sinancevic adds 80cam to his personal best throwing 21.51 which puts him in the final too.
Olympic champion Ryan Crouser is up next in Group B, with the final to take place a couple of hours from now.
A very respectable throw from leader Kat Johnson-Thompson - 42.21 - that's a good start.
She has two more attempts to come.
And launches a 43.95 - a lifetime best for the leader.
Olympic champ Thiam will have to do something spectacular to retain her world crown here.
The Netherland's Emma Oosterwegel has the longest launch so far: 54.01
We also caught up with the absolute legend that is Carl Lewis in Doha, find out what he has to say about the future of athletics, and much more:
With Kevin Mayer out, Canadians Damian Warner and Pierce Lepage (Who currently leads the overall) look best placed to take gold, but Maicel Uibo, Ilya Shkurenyov and Niklas Kaul could all lay claim to the throne.
Warner took the bronze medal at Rio 2016, his career has played out in the shadow of two of the greatest ever: Ashton Eaton, and Kevin Mayer.
You know that cool exterior that world champions have?
Well what's going on in an athlete's head can be very different, we caught up with Noah in Doha and he told us the inside story:
That's it for Mayer.
He battled on bravely after he felt that hamstring twang in the hurdles, but he simply cannot go on any more, pulling up in the run-up to a pole-vault jump.
He drops the pole and flops onto the mat in tears.
This is one of the most unforgiving sports in the world, get better Kevin, we'll see you in Tokyo.
We've seen the triple jump and the long jump in the heptathlon earlier, and if that's whetted your appetite for more, our Podcast this month is for you.
Klishna was the only athlete to compete for Russia in either track of field at Rio 2016, but her Olympic experience was not enjoyable.
She had to take a break from long jumping altogether in 2018 to recover mentally.
The Olympic Channel Podcast spoke to her as she prepares for action on Saturday in the long jump at the IAAF World Championships in Doha:
Johnson-Thompson stays on top after taking off in the long jump event, and with just two more tests to come here's how it stands:
We've seen Kevin Mayer come second in Group A with Ilya Shkurenyov topping the first group, recording a 48.75 throw.
Germany's Niklas Kaul goes to the top of Group B launching a 49.20 on his second attempt, that's the furthest (farthest?) hurl of the evening.
Kaul is a 2016 world U20 decathlon champ and is a podium contender here on his senior debut.
Johnson-Thompson jumps 6.77m!
She's top of the long jump standings with that, in an event we expected Thiam to dominate.
The 26-year-old Liverpudlian won the 2018 Commonwealth Games and she's on course for gold today.
Thiam has a much stronger javelin (Next event) but the British athlete is expected to win the 800m (The final event).
And Thiam's final jump is...
She's shaking her head
6m 40cm, that's 37cm short of the overall leader Johnson Thompson, who has another jump to come.
The favourite jumps 6.25 in her first jump and improves to 6.35m in her second, she can go further, no doubt, one more jump left for her.
Here's how things stand before the competition today, Britain's Katarina Johnson-Thompson is in the lead::
More celebrations like this today please!
The moment Dina's been dreaming of.
Britain's first ever sprint medallist picks up Britain's maiden gold in the 200m, the silver went to the USA's Brittany Brown wears silver.
Big moment too for Swiss sprinter Mujinga Kambundji who not only became the first woman from her country to make a 200m final, but picked up their first medal too.
Here's how it happened yesterday:
21-year-old breakout star Grant Holloway gave us one of the most electric moments of Day 6 in Doha when he won the men's 110m hurdles final in spectacular fashion.
Reigning Olympic champ Omar McCleod crashed out taking Orlando Ortega with him, this was the reaction at Grant's old high school, which he graduated from only three years ago:
He's fighting on, that was huge from Mayer, he liked that!
A 48.34m cast is the furthest anyone has thrown, that's massive from Mayer, all things considered, he harvests 836 points, and passes on his final throw.
But but up steps Ilya Shkurenyov and hurls a 48.75.
Overall leader Warner is up in the next Group.
Well, he made a 'that's it I'm done' gesture after the men's 110m hurdles, but he's back out for the discus throw.
Not a bad attempt either, but his foot touched the top of the rim in the launch circle which means that throw won't can't.
Face of disbelief from Mayer, but it's great to see that he's going to continue.
Rojas makes absolutely sure not to flag up red on that jump, -43cm behind the foul line.
And then clears the auto Q line leaping 14.31 to confirm her presence in Saturday's final.
A little dance to celebrate.
Jamaica's Shanieka Ricketts has the biggest jump so far: 14.42
Behind her is Colombia's always effervescent, always exuberant, always ebulient Caterine Ibarguen, who's second after she pound her thighs, lets out a few screams, gets the crowd a-clapping and leaps 14.32, beyond the automatic qualifying mark.
(That new thesaurus is paying for itself already)
Ukraine's Olha Saladukha and Keturah Orji with Team USA have both cleared the qualifying mark of 14.30 too.
The top 12 will qualify here, so not necessary to clear the Q line.
Rojas saw a red flag on her first jump, she's up next...
The French team is trying to patch up Mayer so he can continue, currently getting massaged on that left hamstring.
Watch this space.
Favourite Warner explodes into that 110m hurdles race and he's away, winning from Mayer who finished really strongly, but looks in pain.
He's wincing and holding his left hamstring.
He makes a 'that's it', 'it's over' gesture.
Is Kevin Mayer, favourite and world record holder, done?
Looks like it.
Ilya Shkurenyov takes Heat 1 in 14.28 collecting 939 points, Maicel Uibo finishes second, Tim Nowak third.
In Heat 2 Kai Kazmirek hits a hurdle and stops running, slapping a hurdle to the ground in disgust, his race is done.
Harrison Williams takes heat 2 in 14.43, Vitaliy Zhuk second and Niklas Kaul.
The three overall leaders are up in Heat 3.
We have a treat coming up in the triple jump too.
The Olympic champion vs. the world champion - that's what we'll see in our second event of the day as qualification gets underway.
Rojas won the Pan Am Games in Lima in August, jumping very impressively, Ibarguen didn't even take part because of injury worries.
Rojas jumped a Pan American record of 15.11m, beating Ibarguen's record that was set at Guadalajara 2011.
Get set for one of the best rivalries in sport here as world champion Rojas goes head to head with reigning Olympic champion Ibarguen.
First up we have the men's 110m hurdles decathlon event, as Kevin Mayer looks to retain his title despite some questions about his fitness.
The Olympic silver medallist has some work to do though, he's currently in third place behind the two Canadians, the leader Damian Warner often leads after Day 1 and he was a little disappointed not to be further ahead at the close play yesterday:
“It feels good to be in the lead, but I was hoping for a better score after day one,” said Warner. “Some of the events didn't go as planned, but I am still in the medal hunt. As disappointed as I am, I am still in the lead.”
Mayer is focused on today:
“I didn't quite get to compete at my best today,” said Mayer. “We started at 4:30pm but I woke up at 7am. I had to wait eight hours. When we do a decathlon, we do not have much time to recover between events."
"All things considered, I did not perform at my best. I still recorded some PBs, but I did not enjoy it as much.
“I hope to regain my rhythm tomorrow,” he added.
“The events in which I struggle the most are over. My second day is better so I can't wait. My rivals are the ones feeling the pressure. I want the world title but I can't take it for granted. I hope to do well to avoid any stress in the 1500m. I am a perfectionist.”
Here's what's up Day 7 of athletics heaven.
With four gold medals up for grabs, here's what we have to look forward to:
Is this a nailed-on cert for the Bahamian favourite Shaunae Miller-Uibo?
Can Salwa Eid Naser find that bit extra and stun the Olympic champ, or do we have another shock on our hands?
A season's best for Britain's Katarina Johnson-Thompson in the final event of yesterday's four hep events left her topping the table overnight, but favourite and Olympic champ Nafi Thiam wasn't all that bothered:
"We'll see tomorrow," she said.
Thiam is dominant in two of three events tomorrow: long jump and javelin.
Johnson-Thompson will have to stay close in those two and then win the 800m grand finale.
It's lining up to be a photo finish, here's how it stands before play today:
Hot favourite in this event, Kevin Mayer didn't have it all his own way yesterday.
And the final event of the day sees Canadian Pierce LePage put down a PB 47.35 in the final 400m heat, the fastest of the three heats, he moves up to second in the overall standings.
Kevin Mayer finished last in the 400m heat despite recorded a season's best 48.99, and alarm bells went off in camp Kevin when he came off the high jump competition holding his knee.
Damien Warner goes into tomorrow's final day in first place, but then he often does... Can he improve in Day 2 events and take a surprise gold?
The decathlon starts up first thing tomorrow at 4:35pm local time in Doha with the 110m hurdles, then it's discus, pole vault, javelin, and the 1500m final.
This one could go right down to the wire.
Here's how it stands:
