Team GB are sitting in first position in the team standings with a combined penalty score of 78.30 ahead of the cross country and show jumping events.

And in the individual standings, Germany's Michael Jung leads from GB's Oliver Townend, with Laura Collett sixth and Tom McEwen in 12th place.

It is the cross country on Sunday and McEwen said: "I think they’ve created a great track. It looks incredible, the grass is incredible, beautifully presented and lots of questions.

“There are lots of short, sharp bursts which isn’t that natural to our horses because we’re used to the big flowing hills.

“With time, horses get a lot more stamina and endurance and one thing we’ve got is three different five-star win under three different horses.

“They’ve all proved that. It will be a different test, you might get away with something early, you may pay for it a little later, it’s covering all the angles and hopefully we’ll be as good as we can be.”

The men's golf competition is into the third of four rounds and Team GB's Paul Casey is among the climbers on what is traditionally known as 'moving day'.

Casey has picked up three shots in his opening six holes and is 10 under overall, one behind American leader Xander Schauffele.

Home favourite and Masters champion Hideki Matsuyama is also at 10 under after three holes, while Shane Lowry is nine under, one ahead of his Irish team-mate Rory McIlroy.

Tommy Fleetwood is moving in the right direction and is up to six under, having picked up three shots in 11 holes.

Back in the 1980s I remember watching kids tv with endless BMX freestyle performances. The only one I ever tried and completed with any success was the endo.

I wonder if Charlotte Worthington's parents were involved in that?

Wherever her talent has come from, the double World Championships bronze medallist is into the Olympic final. Here's the video to prove it...

Just tuning in? What have you missed?

The major news...

- Great Britain won gold in the mixed triathlon relay at around 01:00 BST.

- Great Britain won gold in the mixed 4x100m medley relay moments ago.

- Great Britain's women lost their rugby sevens semi-final to France so they can only now win a bronze medal.

Adam Peaty is asked why is this team so good?

"One word has changed the whole British team - belief. We believe we can win, we believe we can get world records. If you have belief you can build everything around that and we showed that tonight."

The Gold medal winning team talk to Sharron Davies:

Kathleen Dawson: "I was swimming my own race and it didn't matter if it was against men or women."

Adam Peaty: "Mel was just trying to keep me as calm as I can. I get a bit carried away especially when it's for the team. That just proves that tomorrow is going to be another good race but right now it's amazing to a part of these amazing women and Jimmy."

James Guy: "Pulling out of the 100m fly - it really hurt me doing that - I probably could have medalled this morning with that split there but it paid off. Gold medal, world record - can't beat that, especially with that team."

Anna Hopkin: "I was trying not to think about (Dressel chasing her down). I was trying not to think about how far ahead we were from them. It's just irrelevant when you're in the water - you've just got to race. When I turned I saw I still had a good bit of water in front of me and I just went for it. It's an amazing feeling and privilege to be in this team."

I believe Adam Peaty is singing and James Guy is chuckling.

Earlier I pointed to some tremendous deltoids sported by Benjamin Proud. I'll now state Adam Peaty has terrific obliques. Anyone would think he's twisting through water all day long.

Stand under the bunting, grip your cup of tea, give Dave the Bulldog a kick and butter me a scone.

Four Brits are on the podium.

Here's to Kathleen Dawson, Adam Peaty, James Guy and Anna Hopkin.

Now play that anthem...

Fine, let's do ANOTHER mixed relay gold medal ceremony....

American Lydia Jacoby suffered the misfortune of her goggles moving to her mouth on leg two. That proved costly and is an absolute nightmare piece of luck at a key moment.

That's four gold, a silver and a bronze in the pool for Great Britain.

Our children will be born able to swim without the need for armbands and a rubber ring from here on in. A water nation.

Can we just repeat.... James Guy... 100m.... 50 seconds flat.

So if you're just joining us. We've won gold in the mixed triathlon relay and gold in the mixed 4x100m medley relay.

We own relays.

Anyone want to take us on in a relay? Thought not.

Let us just break that down for you.

Great Britain took that out by over a second after their first swimmer - Kathleen Dawson - had a tricky start to her backstroke leg having slipped a little on her push off.

James Guy clocked his 100m butterfly in 50 seconds flat.

A silver for China and a bronze for Australia.

The US - Caeleb Dressel and all - home in fifth.

France hold on to make the final of the women's rugby sevens against New Zealand. Desolation for Team GB who now face Fiji in a bronze medal match at 09:30 BST.

Anna Hopkin wins their fourth gold in the relay.... by miles... and a new world record.

Oh, what a wonderful team!

James Guy is screaming into the Tokyo night.

A world record too of 3:37.58.

It's a new event but still, that is a performance worth screaming about.

Anna Hopkin has the lead... she's going to hold it...
