The fastest-ever time to win a World Championship - that is the way to deliver when you're the favourite!

Nobody could touch Melissa Jefferson-Wooden. She is the champion of the world and she has done it in some style. The tables of last year have turned, nobody was touching her this evening.

Melissa Jefferson-Wooden storms to victory!

She runs the fastest anyone has ever run in a world championship to take the title - 10.61, the fourth-fastest run of all time.

Tina Clayton of Jamaica takes second with a personal best of 10.76 while Julien Alfred, the Olympic champion, is third with 10.84.

Sha'Carri Richardson, the 2023 world champion, is fifth, the legendary Shelly-Ann Fraser-Pryce is sixth in her last solo final aged 38, while Great Britain's Dina Asher-Smith is eighth.

1 - Melissa Jefferson-Wooden (USA) - 10.61

2 - Tina Clayton (Jamaica) - 10.76

3 - Julien Alfred (Saint Lucia) - 10.84

4 - Shericka Jackson (Jamaica) - 10.88

In the blocks.

All eyes on the track.

These are the moments you live for as an athlete. You put all that hard work in behind the scenes, so to actually get yourself to that start line in a major championships final - against the likes of Shelly-Ann Fraser-Pryce and Julien Alfred - is brilliant.

It's moments like these that can really make or break your career.

That is phenomenal from Jimmy Gressier. Last week it was 'Bloquons tout' in France, where they were basically striking and blocking everywhere, and now they will be blocking streets in celebration.

France have never won a medal here, let alone going straight to the top of the rostrum with a gold medal!

Gressier showed his form coming into this, I'm not sure he fully believed going into this but he kept himself in there all the way through.

I'm not sure how he's managed it after that effort, but I've just watched Jimmy Gressier hurdle the advertising board at the side of the track and then haul himself up into the stands to celebrate his 10,000m victory with his family and friends.

The Frenchman is quite the character and that is a victory long in the making. It's his first international track title, never mind a first global crown. A day he will never forget.

And that thrilling finish has got everyone hyped for what's about to come next on the track...

Here's how they line up lane-wise, with their semi-final times listed.2 - Sha'Carri Richardson (United States) - 11.00

3 - Shericka Jackson (Jamaica) - 10.97

4 - Melissa Jefferson-Wooden (USA) - 10.73

5 - Julien Alfred (Saint Lucia) - 10.93

6 - Tina Clayton (Jamaica) - 10.90

7 - Marie-Josee Ta Lou-Smith (Ivory Coast) - 10.94

8 - Shelly-Ann Fraser-Pryce (Jamaica) - 11.00

9 - Dina Asher-Smith (Great Britain) - 11.02

Lane 1 is not being used.

It's almost time for the women's 100m final, with the athletes lining up behind the blocks.

Can Shelly-Ann Fraser-Pryce take a surprise victory in her final championships?

Or might it be Olympic champion Julien Alfred?

Or perhaps Melissa Jefferson-Wooden of the United States, the fastest qualifier from the semi-final.

We'll find out who takes the gold in a couple of minutes.

Dina Asher-Smith will line up for the women’s 100m final out in lane nine after squeezing into the medal race.

But it doesn’t matter how you get there.

Still, it’s hard to look past lanes four and five, containing Melissa Jefferson-Wooden and Julian Alfred, as far as the women’s final is concerned.

They really are stellar line-ups to savour in both finals - and sprinting legend Usain Bolt is in the house to watch it all unfold.

No pressure, everyone…

Well if you've watched athletics for the last 10 years and you tuned in to watch Jimmy Gressier at the European Cross Country Championships with us, when he was running the junior race and the Under-23 race, then you'll remember he slid on his knees after his first big victory and fell flat on his face. He didn't do that tonight.

What a performance from Jimmy Gressier. A brilliant race and a brilliant performance from him - what a finish!

Two laps to go and Andreas Almgren of Sweden is in the lead. This is getting tight!

You can only surge a certain number of times, particularly when conditions are as tough as they are right now. Ordinarily, under normal conditions, you would be able to throw in a number of surges.

Benson Kiplangat is one surge down, so he has one less surge left to play with later in this race.

I do think the result of this race is going to come down to a series of surges. Someone will eventually surge, sustain it and begin to move away.

Everybody is sweating out there, which is what happens with the combination of temperature and humidity. There isn't any sun at the minute obviously, but something in the air did change this afternoon and it is making things so much tougher.

These conditions have been OK for the 400m athletes and sprinters, but not for these long-distance athletes. Everybody is diving for water almost every lap at the minute, that tells you a lot.

Benson Kiplangat of Kenya leads at the halfway mark of the men's 10,000m, having surged ahead just after 5,000m.

This hasn't been a particularly quick race - every now and again there is a surge from a runner, followed by a slowing down. At some point we'll see the final surge when those who think they can win it will make a break for it.

A fifth of the way through the men's 10,000m final and the group is spreading out a bit.

2020 Olympic champion Selemon Barega burst ahead to try and string the runners out, but his early gamble backfired as his opponents gradually caught up with him. He's now dropped back into the pack.

Kenya's Faith Kipyegon has been speaking to BBC Sport after winning the first women's 1500m semi-final heat: "To be honest, I want to thank God to have qualified for the final. My big target was to run a beautiful heat and semi-final, then the big one is coming in the final. I'm so happy.

"It's so beautiful to be a world record holder in your event. It feels so amazing to be on the track and show the fans that I'm capable of doing anything."

We're under way, but this is not going to be an easy race.

World Athletics' warning system when it comes to temperature and humidity has ticked into the red zone, indicating a danger to athletes.

The men's 10,000m final is about to begin.

With Uganda’s three-time world champion Joshua Cheptegei prioritising next month’s Amsterdam marathon, there will be a new name ascending the top of the podium.

Berihu Aregawi will be hoping he's the man taking gold, after he finished in second place at last year's Paris Olympics. The 24-year-old Ethiopian has also finished with silver in this year's world indoor championship and in the 2023 and 2024 world cross country championships, and finished fourth in this event at the Tokyo Olympics and at the world championships in Budapest two years ago.

Compatriot Selemon Barega was the winner over this distance in Tokyo four years ago but the 25-year-old faded to seventh at the Paris Games last summer. He took world bronze in Budapest two years ago. This year he's won his debut marathon in Sevilla and set PBs in the 1500m and on the road over 10km, when he won the Great Manchester Run.

A third Ethiopian, 18-year-old Biniam Mehary, has the fastest time in the 10,000m in 2025 with 26:43.82. He set the world under-20 record last year, and came sixth in the 5,000m Olympic final last year.

Meanwhile 28-year-old Grant Fisher of the United States will also be in contention after winning bronze in both the 5,000 and 10,000m in Paris.

Unfortunately there's no British interest in this event, which Mo Farah won on three occasions between 2013 and 2017.

Athletes are running to the beat of Faith Kipyegon's drum at the moment. It's really hard when you're coaching athletes and they are against her.

She just has every single skill - she has composure, she can run from the front at a fast pace, she can wind the pace up, she can kick at the end. She is just controlling these races and everyone is allowing her to do so.

For those reasons, it's very difficult to say that she's not going to dominate the final.
