Can Caeleb Dressel hunt them down? He has too much to do surely...

Adam Peaty brought Great Britain home two seconds off the lead in fourth. James Guy is in there and he's up against a field largely of women. He's making up water and yes, he edges Britain into the lead.

To Anna Hopkin....

Back in it!

Hannah Smith gives Team GB a lifeline and her try is converted.

Into the final two minutes.

Peaty has caught up the Americans... but we need a lead over them, Great leg there from him.

To Adam Peaty, he has so much to do now, he's fifth and around five seconds down. He's chipping away at the deficit into the last 50m of his leg.

Italy lead, China second and the Russians third...

Not a great start from Kathleen Dawson, who slipped on the wall at the start.

A disastrous start for Kathleen Dawson and Great Britain, she seems to have slipped off the side on her 100m backstroke leg. She's scrapping to stay in it now...

A reminder America's Caeleb Dressel is the only man on leg four. He will likely be chasing down the field.

An error straight from the re-start and France go over for their fourth try. Anne-Cecile Ciofani with her second try. This is drifting away from Team GB. Will they claw their way back into this?

Four names, one team, one medal in sight.

Let's go...

You've got to love the Olympics. British women chasing glory in rugby sevens and now a quartet are by the side of the pool with pressure on their shoulders.

As the late Sir Bobby Robson once told England's footballers..."This is what we have worked for. This is the pinnacle."

A third try for France before the break. How damaging will that prove?

Coralie Betrand goes over and Jade Ulutule kicks the conversion.

It's a cracking match and GB hit back almost immediately through Jasmine Joyce's second try.

Ben Proud atoned for his heats and was talking to Sharron Davies, after the race:

"I was quite upset with myself yesterday. I've put a lot in this meet and i shouldn't have gone that close to getting kicked out in the heats, so I wanted to come in tonight and give it a bit more.

"Now tomorrow we're in the finals - that's the job done, and where I wanted to be. It's going to be a good race tomorrow, that's for sure.

"Obviously Dressel is swimming amazingly well, the rest of the field it's all up for grabs. I want to show the world the work I've been doing with all my coaches this year."

Pocket rocket Jasmine Joyce hauls GB back into this.

The extra points come from Holly Aitchison's kick.

Will they draw level before half-time?

It goes from bad to worse for Britain.

A second try for the French thanks to Seraphine Okemba and it's another conversion by Caroline Drouin.

GB have work to do.

It's a bad start for the Brits as Anne-Cecile Ciofani goes over in the opening minute. It's converted by Caroline Drouin. Strong start by the French.

Who will face New Zealand in the final of the women's rugby sevens?

Here come Team GB.

They're moments from the start of their semi-final against France.

The only male swimmer listed to swim the final leg today...

Caeleb Dressel.

He will be chasing down the whole field one would imagine.

Will he be tired yet? That young man has a fine battery.

Less than 20 minutes until our next major medal hope.

The mixed 4x100m relay brings Kathleen Dawson, Adam Peaty, James Guy and Anna Hopkin together.

We'd love gold number eight of the Games to take us through to breakfast guys.

New Zealand have done it in extra time! They kept hold of the ball for more than three minutes before Gayle Broughton scored the winning try to break Fiji's hearts.

Fiji still have the chance to win a first women's rugby sevens medal but they will be playing for bronze.

Great Britain take on France next in the second semi-final.
