A solid performance from Great Britain's Tyri Donovan.

His lunge on the line was absolutely brilliant, he fully committed. Hopefully there is not too much wrong after that.

The quality in 400m hurdles is huge. You have to expect that standard at the World Championships but it can be intimidating.

Great Britain's Tyri Donovan flings himself over the line and takes second place in heat one with a personal best of 48.26 seconds.

Qatar's Abderrahman Samba finishes first in 48.03 seconds, with USA's Chris Robinson and Jamaica's Malik James-King completing the top four.

Remember, the top four in each heat plus the four fastest non-automatic qualifiers progress to the semi-finals.

The athletes taking part in heat one are out on the track and receiving their introductions, including British champion Tyri Donovan.

Seamus Derbyshire might not be a household name, but you may well ave seen him, with the Britsh 400m hurdler going viral on TikTok for his starting line theatrics at July's Diamond League meet in London.

Upon hearing his name, the 25-year-old emulated the character Glinda's 'toss toss' of her hair from the film Wicked, before showing the camera with kisses and a love heart. The rest is history.

His pre-race routines are "never pre-planned", nor did he begin then with social media fame in mind. Rather, it is part of his commitment to being his "authentic self" after years of battling anxiety around competitions.

Now enjoying his most successful season to date, including becoming the fifth-fastest British man over 400m hurdles in July, he is ready for his first World Championships.

"Last year, I had a really tough year. No matter how ready I was physically, mentally I wasn't," he told BBC Sport. "Being my authentic self has brought me to a point where I feel comfortable again.

"My main target has been to get back competing and back to a place of enjoyment. Moments like this don't come around too often. I really want to relish it."

When trying to work out who might win a medal in the men's 400m hurdles, three names leap off the page.

Prior to the Tokyo Olympics final four years ago, Kevin Young's world record time of 46.78 seconds had stood for three decades.

Now it is only the 25th-quickest time ever, with Karsten Warholm, Rai Benjamin and Alison dos Santos responsible for the top 24.

Norway's Warholm holds the world record (45.94) and is the reigning world champion, but he was pipped to gold in last summer's Olympic final by Benjamin, and was soundly beaten by both Benjamin and Dos Santos in Stockholm in June.

Benjamin has since claimed that he "had a lot left in the tank during that final," so the competition between himself and Warholm will be fascinating.

Don't forget about Dos Santos though - the Brazilian took bronze in Paris last summer, and finished fifth at the 2023 World Championships just 38 days after making his comeback from knee surgery. The 6ft 7' Brazilian is looking back to his best.

Which of this trio will come out on top is anybody's guess.

First up today are the heats for the men's 400m hurdles.

Great Britain have got three athletes involved: Alastair Chalmers, Seamus Derbyshire, and Tyri Donovan.

Chalmers won bronze at the 2022 Commonwealth Games, reached the Olympic semi-finals in Paris and this year lowered his PB to 48.30 seconds.

Derbyshire, 25, is one of the few openly gay athletes at the elite level. He has gone viral for his starting line routines, something he says helps him deal with race day anxiety and stress.

Donovan missed the 2023 Championships with a prolapsed disc, but comes into this off the back of winning a British title last month.

Right, who's ready for our first event of the day?

There are three Brits hoping to go the distance in the men's 400m hurdles, and their quest for gold begins in the heats in about 10 minutes' time.

Let's take a look at who is involved, plus the contenders they are up against.

It is hugely devastating for Molly Caudery.

After the disappointment in Paris and not even making her opening jump and now this. She has had a good season and has been jumping well.

You rarely see occasions like this where you have done everything and you are prepping and then an injury happens. She needs a good team around her to get her through these feelings of doubt.

A reminder that Caudery's dream of winning world pole vault gold was ruined by injury in the overnight session.

We want you to get involved in our coverage and have your say on the big talking points.

Welcome back to Tokyo, where the unmissable action just keeps on coming… and, yes, it’s still a bit hot.

Just beyond the athlete entrance to the stadium, there’s a wall of signatures featuring all the medallists at these World Championships.

Given we’re on day three, they might need to start extending it…

Shall I add Mondo Duplantis’ name to it while I’m here? That’s how confident most are that he will walk away with another gold medal - and possibly even a new world record and the accompanying bonus $100,000 (£74,000) prize money.

No British names to see on here just yet, but 1500m champions Josh Kerr and Jake Wightman will be among those hoping to set up their shot at glory this evening.

The men's marathon was decided by a photo finish after a thrilling sprint for the line between Tanzania's Alphonce Simbu and Germany's Amanal Petros.

Both athletes were timed at two hours nine minutes 48 seconds, with Simbu clinching gold by 0.03 seconds to win Tanzania's first global title.

Italy's Illiass Aouani won bronze but Great Britain's Emily Cairess was unable to complete the race, stopping with less than three of the 26.2 miles remaining after struggling with Tokyo's heat.

"I just got too hot. The conditions were so tough," he said. "I've not known conditions like it."

Great Britain's Molly Caudery's dream of winning world pole vault gold was ruined by injury in the overnight session.

The 25-year-old, the 2024 world indoor champion, rolled her ankle in the warm-up after she planted her left foot into the landing mat after a run-through.

Caudery, who failed to qualify for the Olympic final last year, received medical attention and support from her fellow athletes before leaving the track in a wheelchair.

"Heartbroken... again," Caudery later wrote on social media.

Compatriot Sarah Tait also suffered injury heartbreak after falling at a water jump less than two minutes into her women's 3000m steeplechase heat.

The 24-year-old, who was competing in her first global championship, was unable to continue.

There's another jam-packed evening session coming up on day three of the 2025 World Athletics Championships.

Let's take a look at what's coming up over the next few hours:

11:35 - Men's 400m hurdles heats

11:40 - Men's long jump qualifiers

11:49 - Men's pole vault final

12:23 - Men's 110m hurdles heats

13:00 - Women's hammer throw final

13:06 - Women's 100m hurdles semi-finals

13:30 - Men's 1500m semi-finals

13:55 - Men's 3000m steeplechase final

14:20 - Women's 100m hurdles final
