The USA have pulled one back just before half-time in their crucial pool match with GB.

Abigail Tamer scored her second goal of the match, running across GB's area before slotting past keeper Miriam Pritchard.

That's four paddlers finished. Eight to go, including GB's Joe Clarke.

Spain's Pau Echaniz, who was the first to set off, is our early leader with a time of 88.87 seconds.

An advantage, or added pressure?

Joe Clarke will get a look at all his gold medal rivals before making his dash for gold. He will know exactly what he needs to do to win this title for a second time. He will have the final say.

But, if someone produces something special before then, he will know he has to go all-out to beat them, and that's when the mistakes can start creeping in.

He has been waiting eight years for this since his Rio triumph. What a comeback story this will be if he can pull it off.

That's the question everyone has been asking as they try to stay across what could be the final match of Sir Muzz's professional career. But it is also a difficult to give an exact answer to.

In short, Murray and Evans are playing fourth on Court Suzanne Lenglen.

On court now is the third match between Norway's Casper Ruud and Canada's Felix Auger-Aliassime in the men's quarter-finals.

Earlier I guesstimated the Brits will be playing about 17:30 BST.

Now, with Ruud and Auger-Aliassime still on serve after five games of the first set, Murray and Evans looks to be after 18:00 BST.

We'll give you updates on how things are panning out as the afternoon goes on.

GB's Joe Clarke faces a nervous wait.

He was the fastest in the semi-finals which means he will go last in the final.

You can watch how that rapid semi-final run from Clarke unfolded below.

GB are in control against the United States after Tess Howard twice in the second quarter.

She put her side back in slipping in at the near post to whip the ball past the USA keeper, then finished off a smart move from a penalty corner.

We're about five minutes from the half-way mark.

And we're off!

The men's K1 final is about to get under way and Joe Clarke will hoping to add another medal to Team GB's tally.

Here's a reminder of how it all works...

Canoe slalom, a feature of the Games since 1972, is a timed run on a white-water course.

The discipline includes events raced in canoe (C) and kayak (K) boats.

Athletes in the men's K1 final will attempt to navigate 23 gates, with downstream gates marked green and upstream gates coloured red.

A two-second time penalty is incurred for touching a gate, while there is a 50-second penalty for missing one.

Now then, this bloke has probably got more Olympic medals than some countries have ever won.

While Michael Phelps may no longer be doing his thing in the pool, he's clearly enjoying being able to get out to watch the golf, which I am happy to say has now resumed after a short delay due to the threat of lightning.

"It's fantastic for the USA team. She has a huge amount of experience in goal and she'll offer that to their keepers and bring an extra little bit of something."

Great rebounding.

Abigail Tamer is in there and she is just touching up, there is nothing Miriam Pritchard can do about it.

USA couldn't clear it and Sophie Hamilton is alive to it.

She is able to sneak through and pop it over, it got a little touch from Ashley Hoffman but Hamilton does so well - she lifts it over beautifully.

I have seen the race control boat go past. I cannot remember a time they've had to abandon a medal race and it has happened twice now.

The wind has just evaporated off the course! The GB pair were just making moves.

What's already happened?

• Great Britain add to their rowing medal haul with silver for the women's four, including Helen Glover, and bronzes for the men's four and the women's double sculls.
• Algerian boxer Imane Khelif, one of two athletes cleared to compete in women's boxing in Paris, having been disqualified from last year's Women's World Championships for failing to meet eligibility criteria, through to 66kg quarter-finals after her opponent, Italy's Angela Carini, abandoned their bout inside 46 seconds.
• Former world 1500m champion Jake Wightman is out of the Games with a hamstring injury.
• Skateboarder Sky Brown suffers a dislocated shoulder but the teenager is confident of being able to compete in Paris.
• The GB men's hockey team secure a place in the knockout stages after a 2-1 win over France.
• GB riders Ben Maher, Henry Charles and Scott Brash qualify for the showjumping team final.

What's to come next?

• The GB women's hockey team take on the USA at 16:00, hoping for their second pool win.

• At 17:15, American star Simone Biles starts her bid for a second all-around gymnastics title.
• Can Andy Murray keep on winning in his last tournament before retirement? He and Dan Evans face Taylor Fritz and Tommy Paul of the USA for a place in the semi-finals of the men's doubles some time after 17:30.

It's a crucial clash in the women's hockey this afternoon as Team GB face off against the United States in their penultimate match in the pool stage.

A victory for the Tokyo bronze medallists will put them in a strong position to qualify for the quarter-finals, while a positive result coupled with defeat for South Africa against Spain (starting 16:30 BST) will guarantee their progression.

The USA meanwhile are fighting for their lives, knowing a defeat will put them out of the tournament.

It's not going our way in Marseille.

The first attempt at the medal race for the men's skiff was abandoned earlier today after a wind shift.

And now take two has also been called off, with boats struggling with a lack of wind.

Now then, with thunder and the risk of lightning, play has been suspended at Le Golf National.

Hideki Matsuyama is currently leading and was already in the clubhouse after shooting an eight-under 63 earlier on Thursday.

But the likes of reigning champion and two-time major winner, Xander Schauffele, Jon Rahm and Victor Hovland are yet to complete their first rounds.

Ireland's Rory McIlroy signed for a three-under 68 just over an hour ago and seemed relatively content with his opening round, apart from a bogey on the 18th:

"Solid start. A bit up-and-down, which is to be expected," he said.

"A little disappointing with the three-putt at the last. Something to build upon. With so many events going on spread all across the city, for people to venture out here and to watch us play, it was a really cool atmosphere to play in.

"(I was) not (expecting) this. I thought the weekend, it might get a few more people. I thought the first couple days might be a little bit quieter but it was awesome.

"I'd say maybe 25% were more of a casual crowd or sports crowd rather than a golf crowd. It's nice to play in front of that because it provides a bit more energy. There's a few more flags and there's a bit more, I don't know what the word is, like nationalism. But we were all really well-supported out there. It was great to see."

There's no time to rest if you're a tennis fan. Maybe just grab some refreshments and settle back in for the next batch of quarter-finals.

Novak Djokovic, the 24-time Grand Slam champion, is taking on Stefanos Tsitsipas of Greece at around 18:00 BST, as the Serbian aims to add Olympic gold to his impressive career CV.

Well, who saw this one coming?
