A world record for Simon Ehammer of Switzerland!

He comes in fourth in the 1,000m with a personal best time of two minutes 41.04 seconds, reaching 6670 points to beat Ashton Eaton's world record of 6645 from 2012.

Jeff Tesselaar of the Netherlands won the race in 2:32.49 with the top four finishers all setting personal bests.

American Heath Baldwin finished third in 2:39.06 to seal silver, while compatriot Kyle Garland took bronze with a sixth-place 2:43.43.

Final standings:

• Simon Ehammer (Sui) - 6670
• Heath Baldwin (US) - 6337 (PB)
• Kyle Garland (US) - 6245

Into the last lap and Simon Ehammer is looking very strong.

He needs to beat two minutes 43 for a world record - can he make it?

Three-time world heptathlon champion on BBC Two

Simon Ehammer's had an incredible championships.

The hardest thing in the heptathlon is being able to string performances together and not get carried away with yourself at the same time.

But he has put that distance between himself and the rest of his competitors - and he is on for a world record.

Everything's coming thick and fast on the track.

It's time for the final event in the men's heptathlon - the 1,000m.

Simon Ehammer leads the way here, and should seal the gold medal.

The chasing pack are doing pretty well this winter.

It is possible that Armand Duplantis might not have it all his own way tonight.

It would be great to see a battle at those high heights as this event unfolds.

Armand Duplantis went over at the lowest height - 5.50m - as a warm-up, then is currently sitting out the following 5.70m.

Still very early days in this final.

You don't get a talent like Armand Duplantis very often.

We were very lucky to have Usain Bolt for a period of time. Everybody was concerned about who was going to take the flame after his retirement - and all of a sudden Armand comes along.

He is absolutely changing how we see the event.

In the middle of the arena, the men's pole vault final is under way and it's fair to say the eyes of the crowd are mostly on one man...

Sweden's Armand Duplantis broke his own pole vault world record for the 15th time earlier this month with a jump of 6.31 metres.

The two-time Olympic gold champion most recently cleared the height at the Mondo Classic - an indoor pole vault-only event in Sweden named after him.

Before Duplantis' run, the world record had been held by Renaud Lavillenie of France who jumped 6.16m in 2014.

The 26-year-old has bumped the bar one centimetre over the record each time he has attempted it - and has cleared it 15 times.

Will we see a record of 6.32m cleared this evening?

What a result!

We did have a serious race, there was no doubt about it. We were a bit sceptical because of the time trial nature, but the top three being in this race meant we truly had that competition.

Jereem Richards went out and paced himself wonderfully well.

The jury is out on whether Chris Robinson could've raced that quickly in the first final.

A surprise to start the session!

Chris Morales-Williams steams home in the final 50m to win gold in a new championship record time, 44.76 seconds.

Khaleb McRae takes silver, Jareem Richards bronze. All three medallists came from the second final - they had the benefit of knowing how quick they needed to go.

Khaleb McRae is the world record holder, Jareem Richards of Trinidad and Tobago - in the lane next door - is reigning world indoor champion.

They are the favourites for gold and silver. Let's see how it all shakes out.

Commentator on BBC Two

Well that isn't going to win the gold medal, I don't think...

Chris Robinson is shrugging his shoulders, he has no idea if he has done enough.

Attila Molnar knows his chances of a medal are very slim now.

To misquote the Hobbits - we've had our first final, what about second final?

This feels like a very strange format, but on we go. Khaleb McRae of USA the one to watch here.

Chris Robinson of the United States wins the first of the final races!

It's a time of 45.45 seconds - he now waits to see if anyone can beat that in the second race.

Attila Molnar (45.71) of Hungary is second, Brazil's Matheus Lima (46.17) third.

Kenya's Brian Onyari Tinega (46.62) will definitely miss out on a medal.

It's time for the first final of the evening session - the men's 400m.

A reminder that the 400m events have a changed format this year.

Only lanes three to six are used to reduce the disadvantage of running in lanes one and two, meaning there's a maximum of four athletes allowed in each race.

That means the final has been split into two, with four in each race and the medals awarded to the three fastest overall times.

We have already had some medals decided in the morning session.

The 4x400m mixed relay made its debut at the championships - the first significant change to the programme in 22 years - and Belgium triumphed in a chaotic race, finishing ahead of Spain and Poland.

Outdoor champions the United States were fifth, while Jamaica were disqualified.

Meanwhile Ukrainian Oleh Doroshchuk won the men's high jump in front of Erick Portillo of Mexico, with both clearing 2.30m.

Defending champion Woo Sanghyeok of South Korea took a dual bronze with Jamaican Raymond Richards at the 2.26m mark.

Defending champion Jeremiah Azu narrowly missed out on a medal in "one of the best 60m races of all time" at the World Athletics Indoor Championships in Poland.

Twelve months after claiming the first global title of his career with world indoor gold in China, Azu missed out on a return to the podium by just 0.01 seconds as he clocked 6.46 seconds in Torun.

The 24-year-old always faced fierce competition as he sought to defend his title but displayed his medal credentials by improving his personal best to 6.45 in the semi-finals - a time which moved him to second on the British all-time list behind Dwain Chambers.

But American Jordan Anthony, who arrived at the championships as the fastest man this year, ran the joint-fourth fastest time in history as he improved to 6.41 to take gold ahead of Jamaica's Olympic and world 100m medallist Kishane Thompson.

Thompson and American Trayvon Bromell both finished in 6.45 to complete the podium and deny Azu in a thrilling conclusion to the opening day of action.

Olympic champion and indoor world record holder Keely Hodgkinson controlled her women's 800m heat from start to finish to win in two minutes 00.32 seconds and reached the semi-finals, where she was joined by team-mate Isabelle Boffey.

Ben Pattison, winner of world 800m bronze in 2023, won his heat in 1:47.48 to advance to the semi-finals of the men's event, which also took place on Saturday morning.

Olympic and world medallist Georgia Hunter Bell secured her place in the women's 1500m final by placing first in 4:12.09, but Jemma Reekie missed out after finishing fourth in her race.
