But don't worry if you can't watch the live stream where you are, we've got you covered right here, scroll down for live coverage and updates of everything that happens, as it happens.
Hit refresh for all the latest.
All times below are local time in Doha, Qatar (UTC+3).
Before Doha 2019 they had never won a race walk gold medal, now they have two!
The 20k race walk gold medal goes to Toshikazu Yamanishi. who clocks 1:26.34.
Vasiliy Mizinov wearing neutral colours secures silver 15 seconds behind the winner.
Sweden win their first race walking medal in 28 years as Perseus Karlstrom persists and is rewarded with gold, completing 20 kilometres in 1:27:00.
And that's it for Day 9!
At 17km it's Yamanashi finding the rhythm and racing solo 16 seconds ahead of Sweden's Karlstrom.
It looks like no-one will catch Yamanashi.
China's Cai drops out, absolutely soaked from head to toe.
These conditions are testing the best in the world to the absolute limit, the endurance and mental strength on show is so impressive.
And it's a red card for Callum Wilkinson, his race is over, he's devastated with that.
The two Japanese podium threats have made their way to the front half way through, Toshikazu Yamanishi has upped the pace considerably, he leads at the 10k mark, 17 seconds clear of Sweden's Perseus Karlstrom.
Kaihua Wang and the other fleet-footed Japanese challenger clock 44.23 at the 10k line, in a group of four or five more.
The amount of water the racers are pouring on themselves is incredible, many grabbing two at a time and just showering in the stuff.
No surprise in this heat and humidity.
It's still a tightly packed field at the front, leader from the early stages Dane Bird-Smith still setting the standard at the 5k mark in 22.26.
But there are ten men just a second behind him.
Now it's China's Wang Kaihua who leads after a burst from British competitor Callum Wilkinson.
Wang is chased by Yamanishi with Dane-Smith leading the chasing pack a few metres back.
The race just starting to break apart now.
Our final event of Day 8 has just gotten underway, Japan won their first ever race walk gold medal in the 50km event, Yusuke Suzuki the hero that day.
The 2020 Olympic hosts may win a second tonight and sweep the men's events as Toshikazu Yamanishi and Koki Ikeda take off from the line - they make up two of the three fastest men in the world this year.
But it's Rio bronze medallist Dane Bird-Smith setting the pace early on.
The 27-year-old looks in good form, he won Commonwealth Games gold in 2018.
Now we've all caught our breath again after that flurry of spectacular finishes, we can tell you that was the end of tonight's track events.
But the men's 20km race walk is still to come later, so stay up to date right here!
Steven Gardiner - sensational!
He wins men's 400m gold in 43.48s, a new Bahamas national record.
His fluid, elegant running style makes it look like he's never actually pushing it, but he was there, crashing to the ground at the finishing line, very close to Wayde Van Niekerk's 43.03 world record.
That's a huge result for Pan Am champ Anthony Zambrano from Colombia too, who finishes a race as well as anyone in the world.
Zambrano clocked 44.15 - a new Americas record.
He's finished in the silver medal position, that's a massive boost for the 21-year-old before Tokyo.
It's another podium finish for the U.S. as Fred Kerley bags bronze in 44.17.
Jamaica's Demish Gaye finishes fourth with a Personal Best of 44.46, and such a great story behind him as Kirani James, who has recovered from graves disease this year, finishes fifth in the world.
Favourite Michael Norman's red hot challenge fizzled out in the semis, now it's the Bahama's Steven Gardiner, who takes over that mantle.
Can the elegant runner take it home?
Machel Cedenio, Fred Kerley, and Kirani James, are all in the mix.
It's a Cuba 1-2 Yaime Perez has launched herself to the top of the world in the discus event with a 69.17m in her 5th and penultimate event.
Her teammate Denia Caballero came closest hurling a 68.44 for silver.
Croatia's Sandra Perkovic climbs onto the podium after her 66.72 effort.
Neither Akimenko nor Ivanyuk can clear 2.37 with three attemts each, giving Barshim gold.
The falcon flies to the top of the podium, it's Qatar's first gold of their home Worlds.
That's what the crowd came to see, and they're loving it!
"I'm done, I'm done," says Barshim before grabbing a flag to celebrate with the crowd.
It's silver for Akimenko, bronze for Ivanyuk who pushed one of the greatest to produce a sublime moment.
Barshim is second in line on the all-time greats list, only the great Javier Sotomayor from Cuba has jumped higher than Barshim in history.
Can Barshim become the greatest of all time on the greatest sporting stage there is?
Another captivating high jump contest awaits at Tokyo 2020.
The home hero makes the stadium erupt as he jumps 2.35, then watches Akimenko and Ivanyuk clear that too, so he goes and sails over at 2.37!
That's the world-leading height this year.
That's surely gold, what a story for his first competition back after a potentially career-ending injury.
The 18-year-old Lamecha Girma thought he had it, we thought he had it, everyone in the stadium thought he had it, only Conselsus Kipruto believed.
It's a photo finish, Girma broke and kicked for home but Kipruto caught him by 0.01 of a second!
8:01.35 is the winning time, a new world lead.
Soufiane El Bakkali bags bronze in an 8:03.76 season's best.
Defending champ Conseslus Kipruto ran a serious qualifying heat, can he keep that title?
Morocco’s Soufiane El Bakkali, or any of Ethiopia's big three Chala Beyo, Getnet Wale and Lamecha Girma are all out to take the Kenyan's crown.
Qatar's home hero has knocked the bar twice at 2.33m, he only has one more go or he's gone.
Neutral athlete Mikhail Akimenko is the only one left with a clean card, clearing 2.33 at the first attempt.
Here comes Barshim.
And yes, he's over!
The crowd test the structural integrity of the stadium roof.
That is simply stunning.
She knew she had to run the perfect race with Sydney McLaughlin right on her shoulder.
Such power and acceleration while remaining smooth throughout, Muhammad is a joy to watch.
Dalilah Muhammad goes 52.16 beating her own previous world record.
These two held 7 of the top 8 best times between them this season, but it's the Olympic champion who retains her world crown.
This is such a great rivalry, much has been made of the fact that they're not the best of friends, that McLaughlin is better paid, has a bigger social media following blah blah blah.
But on the track where it really counts it's Muhammad from McLaughlin, and they embrace, mutual respect.
McLaughlin went 52.23 for silver, Jamaica's Rushell Clayton bronze in 53.74.
Akine Simbine has had a great Worlds and he leads South Africa to pole position in Heat 2.
37.65 is a new African record!
Rio silver medallists Japan take second in 37.78, anchor leg Hakim Sani Brown had enough to take a tight race.
And it's another national record for China in 37.79, they're in the final too.
Such a strong team on paper, 100m gold medallist Christian Coleman hands over to silver medallist Justin Gatlin, but there's real problems as Mike Rodgers can't get the baton into Cravon Gillespie's hand before the yellow line.
Are they out? If the baton is passed beyond that yellow line then that's curtains.
Defending champions Great Britain & NI win the heat in 37.56, very smooth transitions takes them through to the final.
They have a fantastic four too:
1. Adam GEMILI
2. Zharnel HUGHES
3. Richard KILTY
4. Nethaneel MITCHELL-BLAKE
News in, green light for the U.S., no disqualification.
Jamaica win Heat 2 with 100m champ Fraser-Pryce absolutely scorching the second leg to set up a Jamaican win.
It's a 42.11 season's best for the Jamaicans.
Here's their line-up:
1. Natalliah WHYTE
2. Shelly-Ann FRASER-PRYCE
3. Jonielle SMITH
4. Natasha MORRISON
Great Britain very close in second, coming home in 42.25.
China qualify in third, Germany just squeezing through too with a small q as fastest outside the auto spots.
The defending champs look very strong in the first heat.
Kiara Parker's locomotion leaves no doubt, anchoring the U.S. to first place.
42.64 is the leading time.
Trinidad and Tobago and Switzerland qualify in second and third.
There were bodies rolling across the track half way through, the Australians crashing out after the second hand-over.
Here's the U.S. team that looks favourite to reclaim their title:
1. Dezerea BRYANT
2. Teahna DANIELS
3. Morolake AKINOSUN
4. Kiara PARKER
We've got a big crowd in the Khalifa stadium tonight and most are here to watch this man.
Rio silver medallist and reigning world champ Mutaz Ezza Barshim is being cheered at every step, he jumps 2.24m the way most of us step over a childproof door.
Clean card, big cheer, Barshim is back.
It's the 2018 European silver medallist Marcin Lewandowski who takes it from the Kenyan Kwemoi who once again gave up a leading position as he did in the qualifiers.
Lewandowski goes 3:36.50.
The youngest Ingebrigtsen is third, Britain's Josh Kerr fourth (Two Scotsmen in the final!), Youssouf Hiss Bachir fifth in a season best and Centrowitz also puts down an SB and gets a wee q.
A third British runner grabs that other small q, Jake Wightman joins his two Scottish teammates.
Look how close that was, the first four within 0.08 of each other.
Heat 2 features the Rio 2016 gold medallist Matthew Centrowitz and Norway's track sensation Jakob Ingebrigtsen, 6 (maybe 7) go through here.
Ronald Kwemoi doing all the running in the first lap as Ingebrigtsen maneuvering into the lead three.
Filip Ingebrigtsen staying on Cheruiyot's heels, the Kenyan setting the pace.
The leader made sure to stay out of any trouble and finishes first in 3:36.53.
But Ingebrigtsen gets swallowed up by a late group hunting in pack.
Algeria's Rio silver medallist Toufik Makhloufi steals into second with a perfectly timed kick, and Neil Gourley is beaming from ear to ear after he also secures a final spot in third.
Craig Engels and Kalle Berglund also grab those final auto-Q's.
First up are the men's 1500m semi-finals.
We'll see both Jakob and Filip Ingebrigtsen in action, Filip can count himself a little lucky after the dig in the back he gave Teddese Lemi before running across his path and clipping the Ethiopian's heels sending him crashing to the ground.
Lemi was reinstated, Filip survived without sanction and they race against each other again in heat 1.
The 1500m is a contact sport, but favourite Timothy Cheruiyot is here and looking fast.
Very excited about the six finals we're about to see tonight.
Here's what awaits on Day 8.
With six gold medals up for grabs, there's plenty to look forward to.
Can 20-year-old rising star Sydney McLaughlin overcome Rio 2016 gold medallist Dalilah Muhammad in the women's 400m final?
McLaughlin ran the fastest semi-final in 53.81, but Muhammad will be out to prove she's still No.1 in the U.S. team and in the world
With Ashley Spencer making it through too there are three U.S. finalists, McLaughlin wants a U.S. clean sweep:
"That's what we're here to do," she said yesterday.
Jamaica's Rushell Clayton will be keen to spoil that party.
Everyone was baffled when Michael Norman just stopped running in the 400m semi-final.
But he didn't stop, he just jogged to the line.
Then we were even more befuddled by his post-race interview where he talked about being confused about which distance he wanted to run and then cited 'warning signs from his body:
"My body gave me warning signs today and I listened to them and made the executive choice to slow down instead of risking injury.
"It's real disappointing to come out here after 330 days of training and not even make the final, not even look good in the semi."
"I've always approached each new challenge as it presented itself. Today my body got the best of me.
"It's disappointing but I just have to take this performance for what it is, and be a better athlete for next year."
Hopefully we'll see one of the most exciting talents in the world of track back soon.
Some say he's the only man alive who can match Michael Johnson's doubleat Tokyo 2020.
In his absence will the grace and pace of Steven Gardiner, be enough to give him gold?
The Rio relay bronze medallist is elegance defined in full flight, and ran the fastest semi-final in 44.13 without even looking like he was trying - the way he does.
But young gun Fred Kerley will fancy his chances with Norman out of the picture and longer distance specialist Emmanuel Kipkurui Korir proved he can cut it with the long distance specialists too.
Korir's 44.34 season best semi-final run puts him in the podium picture.
Can Rio silver medallist and reigning world champ Mutaz Ezza Barshim bring Qatar together again with gold on home soil?
How he would love to.
