We are getting closer and closer to almost having a whole field in the final who have broken 44 seconds. Like we saw in the 100 metres, with every finalist having broken ten seconds, well 9.91 to be exact.

Last week there was talk about a 'slow' pool in the swimming, well this track is certainly a 'fast' one. These guys competing in the 400 metres are just all in form and it is coming together for all of them.

Kirani James delivers and is into his fourth 400m Olympic final.

It's a season best 43.78 seconds.

Zambia's Muzala Samukonga, who won Commonwealth gold in 2022, is second.

I wonder whether Team GB went out fast on purpose to give a false sense of security to Denmark and to make them run outside of their schedule, knowing they had a really strong last four laps. It seems crazy but that is how the race panned out.

On to the second semi-final.

No Team GB athletes involved in this one.

Kirani James of Grenada already has the full set of Olympic medals in this event - gold (2012), silver (2016) and bronze (2020).

Still 0-0 in the first women's semi-final. Looks like extra time is on the way.

Mallory Swanson has had a goal ruled out for the US.

WHAT A RACE.

GB started well, then Denmark took the lead and that gap was getting bigger and bigger.

But GB reeled them back and have now guaranteed themselves another Olympic medal.

But will it be gold or silver? Unfortunately, we have to wait until tomorrow to find out.

That was a rollercoaster.

Great Britain's Sky Brown after collecting a bronze medal in the women's skateboarding park final: “This journey has been crazy with lots of downs but lots of ups.

"Since Tokyo I have learned a lot. A lot of injuries. I was one spot away from qualifying for the surfing. It made me stronger. I am super stoked. I wasn’t even sure I was going to make it here.

“The level for girls skating is crazy. Since Tokyo the level has changed crazily.”

Here's a look at what's happened so far today at the Paris Olympics:

• GB's 16-year-old skateboarding star Sky Brown overcame a dislocated shoulder to win bronze in the women's park final.
• Andrea Spendolini-Sirieix was overcome by emotion after finishing sixth in the women's 10m platform diving final, failing to add to the bronze she won in the synchronised event last week.
• But team GB failed to add to their equestrian medal haul with Ben Maher and Scott Brash coming up short and Germany's Christian Kukuk winning gold in the jumping individual final.

• Britons Laura Muir and Georgia Bell qualified for the women's 1500m semi-finals, while Victoria Ohuruogu made it into the women's 400m semis.

And here's what's coming up:

• Team GB are bidding for a medal in the men's team sprint in cycling, although the Netherlands are favourites to win gold. The final is at 19:10 BST.
• The evening's athletics session is under way, with Josh Kerr bidding for gold in the men's 1,500m final at 19:50 BST.
• The men's long jump final (19:15 BST) and women's 3,000m steeplechase final (20:14 BST) is also coming up, with the much-anticipated women's 200m final at 20:40 BST.

Qunicy Hall of the USA takes victory in the first semi-final.

He crosses the line in 43.95 seconds before taking off his shoes - his feet must be on fire!

Hall set a personal best of 43.80 in Monaco earlier this year so has more to give in the final.

Trinidad and Tobago's Jareem Richards finishes second to also reach the final.

It's fourth for Charles Dobson.

A false start for Denmark.

Time to reset.

There are two Team GB athletes in tonight's 400m semi-finals - you can see how they came through the heats below.

Charles Dobson goes in the first semi with Matt Hudson-Smith in the third.

The first two in each heat qualify for tomorrow's final and next two fastest also advance.

The emotion has just hit Keely Hodgkinson as she steps up to the top of the podium, to be presented with her Olympic 800m gold medal after an outstanding performance last night.

There is terrific British support at the Stade de France again this evening in anticipation of another gold but the whole stadium celebrates Hodgkinson's crowning moment after her run of three successive global silvers.

Teary-eyed as the national anthem is played, she just about holds it together before world champion and Mary Moraa gathers the medallists for a quick selfie.

It is the moment she had dreamed about for so long. Keely Hodgkinson, Olympic champion!

Three years ago in Tokyo, GB faced Denmark at this exact stage of the competition - and it ended with the Brits crashing out in controversial fashion.

In happier times, GB beat the Danes to European gold earlier this year.

Win again tonight and they’re through to the gold medal race tomorrow.

We've switched to athletics on BBC Two. Here's tonight's schedule:

18:35 - Men's 400m semi-finals

18:57 - Women's hammer final

19:07 - Women's 400m hurdles semi-finals

19:15 - Men's long jump final

19:50 - Men's 1500m final

20:14 - Women's 3,000m steeplechase final

20:40 - Women's 200m final

All three GB riders performed perfectly to the plan that they had and that's the best performance we can see from them.

Mistakes happen, we're expecting the silver medal now but anything can happen in sport. There is so much tension.

It's not over yet, you never know.

Still nothing to separate these teams. What a chance for USA's Mallory Swanson a few minutes ago. She did all the right things, dribbled past several players to get into the box, but could only pull her finish wide of the right post. Germany have had chances of their own, Julia Gwinn going the closest.

It does have the feeling at the moment that this game could be one to go all the way through extra time and nervy spot kicks.

There is room for improvement, sadly, for the Dutch.

I think they could go sub 41 which is incredible, asbolutely incredible.

Any time during the Olympic cycle, they step up and they are just a length ahead of everyone else.

Team GB are seven bike lengths behind them at that pace.

Coming up next at the velodrome is the men's team pursuit first round.

Great Britain’s quartet of Ethan Hayter, Ollie Wood, Dan Bigham and Ethan Vernon qualified with the second fastest time yesterday, behind Australia.

In today’s first round heats, they face Denmark, with Charlie Tanfield coming in at P3 for Bigham.

Bigham’s said on Instagram he had a “pretty big crash” on Saturday and so is taking today out as part of his recovery. He did appear to have a lot of strapping on his right shoulder yesterday.

Here's what is still come in the velodrome tonight.

Now: men’s team pursuit - first round

18:55: men’s team sprint - quarter-finals

19:00: men’s team sprint - semi-finals
