Setbacks are inevitable in sport, but the brutal nature of the first major sucker punch of Keely Hodgkinson's career is that it followed the pinnacle. Two torn hamstrings later, the Olympic 800m champion would not change a thing.

After a 376-day wait to make her competitive return following that crowning moment at Paris 2024, the 23-year-old's explosive comeback in August suggested she has timed her comeback to perfection.

On Sunday she will attempt to achieve a British one-two with training partner Georgia Hunter Bell in the world 800m final.

"The last 12 months have been quite a journey," Hodgkinson told BBC Sport. "Weirdly, though, I wouldn't change any of it because I've learned so much.

"It's got me to where I am now, so I can't complain too much, but it's definitely been the most challenging year so far."

I am feeling sick. I am very hot, my palms are sweaty. I need this 800m out of my life. We've built this up the whole championships and it's in half an hour.

We can't discredit that Keely is here and two months ago we weren't sure she'd even be here.

Great Britain's Keely Hodgkinson and Georgia Hunter Bell will meet in the women's 800m final at 11:35 after the two training partners continued their seamless progress through the rounds.

After Olympic 800m champion Hodgkinson and Olympic 1500m bronze medallist Hunter Bell both won their heats on Thursday, they safely finished inside the top two automatic qualification places in their respective semi-finals.

Hodgkinson won her heat in one minute 57.53 seconds, while Hunter Bell crossed the line behind Kenya's defending champion Mary Moraa.

They will attempt to become the first British athletes to secure a one-two at a global championships since Christine Ohuruogu and Nicola Sanders in the women's 400m in the Japanese city of Osaka, 18 years ago.

Great Britain's Morgan Lake is under way in the women's high jump final.

She's cleared 1.88m at the first attempt.

I attended World Athletics president Sebastian Coe's end-of-championships news conference a little earlier on.

The future of the sport was discussed at length, including gene testing which was introduced for these championships - and which Coe confirmed are here to stay [see the post at 10:50].

The conference ended on a light note, as Coe spoke about last night's brilliant men's 800m final.

That saw GB's Max Burgin edge ever closer to Coe's 44-year British record, among a high-class line-up from which many believe Kenyan David Rudisha's 2012 world record will soon be beaten.

“It was quite amusing because I watched it with David Rudisha," said Coe.

"We both hugged each other at the end of it because we were both survivors – his world record and my British record.

"We were the survivors club last night. It was a great race.”

It's going to be an exciting final day of the championships, and as always, we want to hear your opinions, hot takes and predictions.

Here's a reminder of Morgan Lake's two metre clearance at August's Diamond League final in Zurich...

Morgan Lake has been in excellent form of late and the British athlete cruised her way through qualifying in the women's high jump.

The 28-year-old was one of eight athletes to finish joint-top of the standings, having made a mark of 1.92m.

In August she became the first British woman in history to clear a two metre jump, and now has her eyes set on a possible medal in Tokyo.

To do so she will have to overcome at least one of the 2024 Olympic medallists - Ukraine's champion Yaroslava Mahuchikh, and the Australian pair of Nicola Olyslagers and Eleanor Patterson.

The big news overnight from the decathlon was the disqualification of Norway's Sander Skotheim after an infringement in the 110m hurdles.

He was in second place and in contention for gold up until that point.

USA's Kyle Garland currently leads the pack with just the javelin (which is ongoing) and 1500m to go.

Germany's Leo Neugebauer follows closely behind the American in second with Puerto Rican Ayden Owen-Delerme in third.

Here's when you need to be in front of the TV/reading the live text:

Here's the medal table going into the final day of the World Athletics Championships.

GB are 22nd, three places above the Republic of Ireland, having finished seventh with a record-equalling 10 medals two years ago.

They had targeted a top eight finish.

World Athletics president Lord Coe confirmed in an interview with BBC Sport that all female athletes competing at the championships have undergone new gene testing.

And at a news conference on Sunday, he confirmed the tests would continue at future events.

"Let me be clear, the gene test is here to stay," he said.

Rules requiring all athletes in the female category of world ranking events to take a one-time gene test came into force at the beginning of September.

World Athletics says the sex screening - which detects the presence of a Y chromosome - is to protect the integrity of women's competition.

Coe could not confirm if any athletes had been prevented from competing as a result of the test, carried out via cheek swab, as such discussions are only held between the athlete and a relevant medical delegate.

The perennial champions have taken the second chance given to them by an infringement from the Zambian team.

Lucky them, because on Saturday they had a shocker...

This morning we had the very unusual sight of teams being given a second chance to reach today's relay finals after some absolute madness during the heats yesterday.

The United States and Kenya contested a shoot-out men's 4x400m to qualify for the final after Zambia were disqualified for an infringement.

This was won by Olympic champions USA, who will take their place as the ninth team in that final.

Italy were disqualified from the men's 4x100m final for infringing South Africa, who were unable to finish their heat.

The South African team were given the chance of a solo relay time trial this morning to see if they could progress to the final.

They needed to make a time of 38.34 seconds to get into the final, but they could only manage 38.64 so there will be eight teams in the final.

World Athletics president Lord Coe says the location of warm-up facilities at the World Championships in Tokyo is "not perfect", following complaints from athletes including Great Britain's Keely Hodgkinson.

Yoyogi Park, where the main warm-up facility is located, is a two and a half kilometre drive from Japan National Stadium, a bus journey which takes about 15 minutes.

It means athletes are catching a bus around an hour before they compete, with Olympic 800m champion Hodgkinson describing the situation as "draining".

Coe says transport and logistics have been a challenge but the organisers have done their best.

"We need to make sure that we have great transport systems," he told BBC Sport.

"It has been a challenge here because, of course, post-Olympic Games we lost the warm-up track we used during the Games.

"It is a little bit further away and we have had to deal with traffic flows at different times of the day, different days of the week.

"We have really looked at that. It isn't perfect, but I think the athletes are now recognising we've done everything we possibly could to make it as good as possible."

World heptathlon bronze medallist Katarina Johnson-Thompson, speaking to BBC Sport: "I have no words. I'm still in a bit of disbelief.

"I've done this so many times it doesn't get any easier. If anything, I had the least confidence coming into this. It really does mean the world to me."

On earning a medal at the arena where she suffered an injury during the 2020 Olympics: "I've been through it in this stadium. It holds so much emotion and to finish the 200m yesterday meant the world.

"To finish with a medal this time around, I can't put into words the full-circle moment I've just been through."

On her physical and mental state: "It's been physically and mentally exhausting. It's hard to get yourself up for the fight again knowing how hard it is.

"I said last year, as long as I'm competitive I'll be here. In 2016, I remember I said 'this is the last time you'll see me'. I say this when I win and I say it when I lose, give me a month off and I'll be asking when training is."

Great Britain's Katarina Johnson-Thompson captured an emotional fourth global heptathlon medal in unprecedented circumstances as she shared world bronze with American Taliyah Brooks in a dramatic concluding 800m in Tokyo.

Competing at the stadium where she suffered Olympic heartbreak four years ago, Johnson-Thompson, 32, did not know how to react as she continued her late-career resurgence by making a third consecutive major podium.

Needing to beat Brooks by about six seconds to leapfrog her rival on to the podium, Johnson-Thompson wore a puzzled look as it was confirmed they had finished on exactly the same points.

But the tears began to flow when her name - and Brooks' - appeared lit up in bronze on the big screen, tied on 6,581 points to become the first heptathletes to split a world medal.

American Anna Hall claimed a breakthrough world title triumph and Ireland's Kate O'Connor held on for a historic silver, after three-time Olympic champion Nafi Thiam withdrew from the competition when ranked eighth earlier on Saturday.
