I don't think we know what it will do to the global calendar of athletics. It is just a different product.

A lot of the athletes said that they wanted something different, something social media friendly, something for the TV and a lot of the stakeholders want to see something different.

But the overall picture and the landscape isn't clear, there are lots of changes to athletics in the next few years with the Diamond League.

There is place for this, but I do think it is unclear what yet.

It has been great.

Now the pace begins to rise.

Likina Amebaw moves to the front and puts her foot on the gas.

Very quickly, it is four Ethiopian athletes at the front - but Amebaw is going clear and already has a huge advantage.

Has she judged this right, or is it too much too soon? Still more than one kilometre remaining, but she looks relaxed.

Hannah Nuttall is following Germany's leader Maureen Koster, with the Ethiopian contingent happy to chill in the group for the time being.

They're averaging three minutes per kilometre, which isn't too demanding for many of the athletes in this line-up.

I have loved it, the energy in here is fantastic, people have wanted to see something that looked different and felt like a different product.

They have delivered, World Athletics has delivered.

Energy, lights, actions and it seems that the athletes have been enjoying themselves.

Hannah Nuttall goes in the women's 5,000m final in the next event on the track.

This race features six of Ethiopia's seven season-leading athletes in the event.

Likina Amebaw leads the way with a season's best of 14:18.41.

Nuttall ran a 2026 best time of 14:51.34 in finishing fifth at the Commonwealth Games. It is going to be a tough ask for her to hang on to the Ethiopian contingent in this final.

Keely Hodgkinson was again denied a major prize by rival Audrey Werro - but revealed she had overcome a torn hamstring to make the start line at the World Athletics Ultimate Championship.

Britain's Olympic 800m champion sustained the injury while competing in the European Championship final less than a month ago, when she was dethroned by 22-year-old Swiss sensation Werro.

Hodgkinson, who was forced to miss Diamond League races in Zurich and Brussels, said following her second-place finish in Budapest that it was "touch and go" whether she would be fit to compete.

Werro controlled Saturday's 800m race from start to finish, winning in one minute 55.88 seconds to underline her position as the event's current leading athlete.

Hodgkinson, who despite her injury setback overtook Femke Broeders-Bol on the home straight for second in 1:56.26, said: "On the outside, people might think I'm disappointed - but I'm actually quite proud of how I approached that.

"I unfortunately tore my hamstring during that race [at the Europeans], so I didn't know if I was going to be here.

"It's been a bit of a frustrating season but, I think overall, I'm finishing second in the world and I can't really be too hard on myself for that."

Much better from Amy Hunt, 22.22 seconds, an all-round nice number. She is so good and very strong in the last 30-40m.

Very nicely done by Amy Hunt.

She shakes off her 100m disappointment to put in a classy 200m performance here, gliding off the bend and powering clear to win in 22.22 seconds.

Success Eduan misses out as she crosses the line eighth in 22.93, but what a season it has been for her despite balancing athletics with university.

Here we go then.

Can Amy Hunt and Success Eduan put in big performances here?

They're joined by Shaunae Miller-Uibo and Anavia Battle as they battle for a spot in the final.

It was as good as done as soon as he launched his 91.09m final throw.

Sri Lanka's Rumesh Tharanga Pathirage takes a dominant win in the men's javelin final.

He's a bit to eager to lift his trophy, though, holding it aloft before they've had chance to start the sprinklers off.

Ah, there they are. The music kicks in and now he will have his moment.

Britain's Success Eduan joins Amy Hunt in the second women's 200m semi-final, having already earned one of the biggest paydays of her early career with $6,000 after GB's third-place finish in the mixed 4x100m relay.

Some of that money, she says, will likely go towards paying off her student loans. The 21-year-old trainee midwife still has four babies to deliver next week before completing her degree at Salford University.

“I’m finishing hopefully next week. I still have one more placement. Unfortunately I didn’t get my births two weeks ago, so I’m just going to get all my births done," Eduan said.

“I’ve got four more left to deliver. I arrive in Manchester on Monday afternoon, and I have a Monday night shift that day. Three nights, so I finish on Thursday morning."

Sri Lanka's Rumesh Tharanga Pathirage took charge of the men's javelin final with a huge 87.11m third throw.

That's almost a metre further than any of his competitors have managed so far.

But he's just gone even further in the final round!

That will surely be unbeatable here. A massive 91.09m to beat.

Olympic champion Gabby Thomas sends a message to her rivals as she finishes strong to beat 100m champion Melissa Jefferson-Wooden to victory in the first of the women's 200m semi-finals.

Thomas crosses the line in 21.88 seconds to lead the qualifiers, with Jefferson-Wooden finishing in 22.15.

Was the world champion tired there? Or simply conserving her energy? We will find out at 19:49 BST.

Amy Hunt returns to action shortly, having been left disappointed by her eighth-place finish in a stacked women's 100m final last night.

That was won by American world champion Melissa Jefferson-Wooden, ahead of Olympic gold medallist Julien Alfred, in a world-leading 10.62 seconds, the joint-seventh fastest time in history.

After winning her first individual global medal with 200m silver last year, the 24-year-old Hunt achieved a historic four gold medals at last month's Europeans.

The next challenge, and ultimately Hunt's ambition, is to replicate that on the global stage.

Hunt told BBC Sport: "I feel a bit disassociated right now. That's the first time dealing with having a 100m semi, then having to regroup and go back out [for the final].

"I don't think that I did myself very proud in that race but I'm lucky to be able to go to sleep tonight and come back out tomorrow in my more favourite event and see what happens."

Dos Santos is reigning supreme at the moment.

Everything about him is so fluid. The fact he can hurdle so beautifully and effortlessly... Where is the world record going to finish?

One of the big talking points around this inaugural Ultimate Championship has been the huge money on offer.

World Athletics is providing "the richest prize pot in the history of the sport" with a total of $10m (£7.4m) to be won in Budapest.

Each individual event winner will pocket $150,000 (£110,000) - more than double the offering at last year's World Championships.

The runner-up will get $75,000 (£55,000), and $40,000 (£29,500) will go to the athlete placing third.

In the relay events, the winning team wins $80,000 (£59,000).

Alison dos Santos knew how important that was and that was his first opportunity to show how good he is and that he is the world number one.

Alison dos Santos is the Ultimate champion!

The Big Three enter the home straight almost perfectly aligned, before the Brazilian storms to a dominant victory in 45.98 seconds.

American Rai Benjamin holds out for second in 46.40, ahead of Karsten Warholm in 46.78. Great race!

What has Alison dos Santos on the Big Three of the men's 400m hurdles got in store for us here?

Brazil's Dos Santos smashed the 400m hurdles world record in Zurich last month, leaving former record holder Karsten Warholm far behind as he clocked a time of 45.80.

American Rai Benjamin will also attempt to push him all the way.
