American champion Kyle Garland is on course to bring yet another gold to the USA as he leads the decathlong after the first three of 10 events.

A 10.51 run in the 100m, 7.92m leap in the long jump and 17.02m throw in the shot put has given him a 162-point lead over the rest of the field.

Olympic silver medallist Leo Neugebauer and 2024 world indoor champion Simon Ehammer are currently in second and third respectively, just ahead of Puerto Rico’s Ayden Owens-Delerme.

Damian Warner, who won Olympic gold in this stadium in 2021, was a late withdrawal from the competition after sustaining an achilles injury in warm-up.

There will be no British men in the discus final after both Lawrence Okoye and Nick Percy came up short in qualifying this morning.

Okoye broke his own British record in April with 70.76m, but came nowhere near that in Tokyo. His longest distance of 63.50m was only enough for 15th - outside the top 12 who advance to the medal event.

His compatriot Percy threw 57.08m, putting him 33rd of the 37 competitors.

Sweden's Daniel Stahl led qualifying with 69.90m, ahead of Kristjan Cej, the 2022 world champion, in second and Lithuania’s world record holder and Olympic silver medallist Mykolas Alekna in third

Spain's Maria Perez has become the first woman to complete the world championship race walk double after adding 20km gold to the 35km title she won last weekend in Tokyo.

The 29-year-old is now a four-time world champion after finishing in the second fastest time of her career, 1:25.54.

SIlver went to Mexico's Alegna Gonzalez, while Japan's Nanako Fujii won bronze for the host nation's first ever world medal in this event.

In the men's 20km, Brazil's Caio Bonfim upgraded his 35km silver to gold. China's Wang Zhaozhao took silver with Spain's Paul McGrath earning bronze.

There was disappointment for Japan, as world record-holder Toshikazu Yamanishi appeared on course for victory before a two-minute penalty late on saw him drop from medal contention.

As well as the heptathlon long jump, there were a few events overnight - including some medals and Brits in action...

There is more to Noah Lyles than just the showmanship, the grandstanding and the dyed orange hair.

The irrepressible American held off a stellar field in the 200m final at the World Athletics Championships in Tokyo on Friday to win his fourth successive world title in the discipline.

It forms a stark contrast to his Olympic results in the discipline – bronze in Tokyo in 2021, the same last year in Paris amid struggles with Covid.

But back in the Japanese capital, Lyles banished the painful memories Tokyo previously held to equal Usain Bolt's title record.

"I can't wait for 2027 to become the only man to win five 200 metres titles," said Lyles.

"I don't have good memories from Tokyo in 2021. At that time I was depressed, but this time I am energised. I love what I do and I am happy.

"My face is blasted everywhere over Tokyo. This is a joyous moment I am going to keep with me forever."

World 200m silver medallist Amy Hunt, speaking to BBC Sport: "I am so proud of myself for choosing the harder path.

"I could have chosen an easier way out many times. I chose to go to Cambridge to get a degree - in part for myself to look back on and be proud of, but also to show other young sports people, other young girls that you don't have to give up education.

"You can be an academic badass and a track goddess.

"I just beat some amazing girls and I can't believe it. I am showing that you can do everything. Anything you set your mind to, you can be the best at everything."

On how she would celebrate: "Maybe some karaoke tonight!"

Great Britain's Amy Hunt announced herself on the global stage by claiming a superb 200m silver in her first major final at the World Athletics Championships in Tokyo.

The 23-year-old stared up at the screen in disbelief before bursting into celebration and skipping down the track as her breakthrough achievement was confirmed.

Reaching for the line, Hunt edged out Jamaican sprint great Shericka Jackson for second place as American Melissa Jefferson-Wooden completed a dominant clean sweep of the sprint titles after gold in the 100m, while Dina Asher-Smith came fifth.

It was GB's second medal of the championships, following Jake Wightman's silver in the men's 1500m.

"I have not stopped smiling or crying!" Hunt told BBC Sport.

"As soon as I saw my mum, I burst into tears. I knew I could do it as long as I put in a good turn and was with them off the bend. I am so proud of myself."

Let's get some reaction to yesterday's action - starting with a remarkable medal for GB in the women's 200m...

This is how the event will conclude on Saturday - all times BST:

11:00 - Javelin

13:11 - 800m

The biggest news from the heptathlon this morning though is that Belgium's Olympic champion Nafi Thiam has withdrawn from the event.

Thiam was eighth with two disciplines to go - although one of them, javelin, is arguably her strongest.

Thiam has split the past four world golds with Katarina Johnson-Thompson but her build-up was disrupted by a disagreement with Belgian Athletics.

The 31-year-old's federation have rejected her claims that she was blocked from joining the team camp before the championships for refusing to sign its code of conduct.

Prior to her withdrawal, Thiam told Belgian newspaper DH Les Sports+, external: "It was difficult from the beginning. I tried to fight, to go through these difficulties, but clearly it does not follow. I have trouble explaining it myself.

"Clearly my body is not happy. I don't want to do anything stupid, because I think that now, finishing would be for the principle."

And her coach Michael van der Plaetsen has since confirmed Thiam is out of the running.

GB's Katarina Johnson-Thompson, speaking to BBC Sport: "It was hard to get going this morning, it was such a quick turnaround.

"I felt good, the body felt good, I'm just really gutted about that final no jump.

“It just shows the margins in sport. You can't really get any closer."

Defending champion Katarina Johnson-Thompson remains in medal contention with just two events remaining as she bids for a third world heptathlon title in Tokyo.

Johnson-Thompson will begin the final session of the competition in third place, 167 points behind American leader Anna Hall and 59 behind Taliyah Brooks.

The 32-year-old recorded a long jump best of 6.42m on Saturday, after marginally fouling on a much bigger leap with her third and final attempt.

It took her to 4,874 points before the javelin and 800m.

Ireland's Kate O'Connor dropped to fourth, 50 points outside the podium places, while GB's Jade O'Dowda rose from 15th to sixth with a long jump season’s best of 6.49m.

Welcome to day eight of the World Athletics Championships in Tokyo. It's the penultimate day of action - doesn't time fly?
