Here we go then. Both Brits race in the first heat of the 100m hurdles.

A huge ovation greets the names of Jade O'Dowda and Katarina Johnson-Thompson being read out.

KJT tops the applause-o-meter.

I think Katarina is looking good. She had a fantastic year last year, becoming world champion for the second time.

She has got some great speed and is very good over the hurdles. It will be a good indication after the hurdles as to how her last few weeks have gone, going into the Olympic Games.

No waiting around this morning if you're keen to see the Brits in action.

Both Katarina Johnson-Thompson and Jade O'Dowda go in heat one, as does Ireland's Kate O'Connor.

Cracking morning for a run. And a hurdle. Or a throw.

The Stade de France is basking in the early morning sun, the purple track glistening like lavender fields of the south of France which it is representing.

Lots of huge events coming up and we've already had an important one - a race between two mini remote control cars.

I think France won it. Quelle surprise...

Johnson-Thompson has been around competing at the highest level for such a long time but unfortunately at the Olympics, it has never turned out how she hoped.

I really hope this is going to be her time to end on a high.

The heptathlon begins this morning with the 100m hurdles kicking off the seven-discipline event at 09:05 BST.

World champion Katarina Johnson-Thompson is Great Britain's great medal hope but in a glittering career that has seen her take gold at two World Championships - 2019 and 2023 - as well as at the 2018 and 2022 Commonwealth Games, the 31-year-old is yet to produce her best at the Olympics.

The Liverpudlian, 31, finished 14th on her Olympic debut in 2012, came sixth four years later in Rio and injury prevented her from finishing in Tokyo three years ago.

Her triumph in Budapest last year showed what she is capable of but injuries remain a nagging concern.

Johnson-Thompson withdrew from the European Championships after just three events in June but she has since returned to action and will hope that this is the year she is finally able to put it all together at an Olympics.

If she does then, despite tough competition from the likes of two-time defending champion Nafi Thiam of Belgium, a first Olympic medal could be within her grasp.

Staying with Netherlands success and Marit Bouwmeester has become the most decorated female Olympic sailor by claiming dinghy gold.

Bouwmeester, 36, has overtaken Britain's Hannah Mills, who won three Olympic medals - two gold and one silver - across three Games between 2012 and 2020.

Denmark's Anne-Marie Rindom won silver in Marseille with Norway's Line Flem Hoest taking bronze.

"It's nice to finally finish it off - it hasn't sunk in yet," Bouwmeester said.

"I have so much respect for Line and Anne-Marie, we push each other all the way."

Bouwmeester won silver at London 2012, gold at Rio 2016 and bronze at Tokyo 2020.

In the men's dinghy event, Australia's Matt Wearn made it back-to-back gold medals following his success in Tokyo.

Pavlos Kontides of Cyprus picked up his second silver at his fifth Games, and bronze was claimed by Peru's Stefano Peschiera, despite collecting several penalties in the final.

Team GB's Micky Beckett, appearing at his first Olympics, finished sixth overall.

Sharon van Rouwendaal showed all her experience. What a swim!

This was all about experience. There was two Olympic debutants with her in the closing stages, they were lucky they had her to navigate for them.

What an effort this is from these women! They've been swimming for over two hours in the River Seine.

The Netherlands' Sharon van Rouwendaal is the new leader with Australia's Moesha Johnson in second and Italy's Ginevra Taddeucci in third.

They're into the finishing straight!

Australia's Moesha Johnson has been in the lead for the majority of this race, is she going to hold on to the gold?

The Netherlands' Sharon van Rouwendaal and Italy's Ginevra Taddeucci are right there with her and will look for a sprint finish.

It looks like we're in for an exciting finish in the women's 10km marathon swim and you can watch that now on BBC One before some women's basketball highlights of USA v Nigeria in the quarter-finals.

Meanwhile, on iPlayer and the Red Button, you can watch the early stages of the second round in the women's golf at Le Golf National.

After five laps, you’d expect no mistakes from the swimmers as they know their way around.

They are keeping tight to the bank for as late as possible, it is unlikely for an error now.

There's just two seconds seperating the leading three women.

We could be in for an exciting finish here!

Matthew Hudson-Smith
British 400m runner on BBC Radio 5 Live

I am so happy. I am ecstatic as I know this is just the start. I am healthy which is a big thing, and this is just the start. I am just going to keep building here really and keep going.

The feelings were, after 2021, I felt that in three years I was not in the sport mentally that I am now an Olympic silver medallist and the fifth fastest of all time. It was happiness rather than bitterness. It was the second-fastest race in Olympic history. It's history at the end of the day and I am glad to be a part of it.

It wasn't the perfect race at this time. I know there is more in the tank and other areas I can work on. This is just the start.

Great Britain's Matthew Hudson-Smith came within touching distance of the 400m gold medal.

After overcoming the odds and claiming silver, he spoke to BBC Sport's Harry Poole in Paris.

"Sometimes, the journey is better than the outcome," Hudson-Smith told BBC Sport.

"It has been one hell of a journey and I am just grateful. I saw everyone in the crowd, they were all proud.

"They know what I have been through. They know that it has been a rough journey. Incredible highs and deep, deep lows."
