But before we get stuck into all that, let's have a recap of what's happened so far on day 10 at Tokyo 2020:

• British pair Laura Muir and Katie Snowden safely progressed to the semi-finals of the women's 1500m, while world champion Sifan Hassan recovered from a fall to win her heat
• Beth Dobbin is into the women's 200m semi-finals after finishing second in her heat, ahead of Jamaica's Elaine Thompson-Herah, but 100m bronze medallist Shericka Jackson has missed out
• Briton Nick Miller has made the hammer final
• Greece's Miltiadis Tentoglou prevailed in a dramatic final round of the men's long jump final, claiming gold with his final leap
• Jasmine Camacho-Quinn won Puerto Rico's first ever track and field gold in the women's 100m hurdles final
• GB's Deborah Kerr has qualified for the women's kayak single 200m semi-finals

USA v Canada is go!

Both sets of players take the knee before Nichelle Prince gets this women's football semi-final under way.

The winner will play either Australia or Sweden in Friday's gold medal match.

Gadirova twins in action soonpublished at 09:00 British Summer Time 2 August 2021

Women's floor, men's rings, men's vault finals

After a relatively quiet couple of hours in Tokyo, the action is now coming thick and fast - with plenty of British interest too.

Twins Jessica and Jennifer Gadirova are in action in the gymnastics women's floor final from 10:00 BST.

The 16-year-olds have already charmed the nation with their joyful routines in the team and all-around finals, but Jessica might go one step further today.

She was crowned European champion on the floor earlier this year and now gets her chance on the world stage.

Jennifer was called into the final when defending champion Simone Biles withdrew.

GB's Katie Archibald on BBC One: "We're happy with the time, not the result. We thought we'd be just on the long side of what the Germans did and we just found out we didn't have it in that last kilometre."

GB's Josie Knight: "I was incredibly nervous - I'm with three defending Olympic champions. We gave a good ride, but I think we've got more in the tank."

It's heating up as we head to the fifth round of the men's 3m springboard as British pair James Heatly and Jack Laugher both squeeze into the top 10.

Heatly scored 85.75 with his fourth dive and is now in 10th spot while Laugher scored 84.60 and is in sixth place with two more rounds to go at the Aquatics Centre.

A reminder that the top 18 divers will head through to the semi-finals.

As we've been telling you, Great Britain's eventers are well placed for team and individual success this morning,

After impressive cross country displays, world number one Oliver Townend, Laura Collett (pictured) and Tom McEwen lead the team event ahead of Australia and France.

Townend tops the individual standings, with Collett third and McEwen sixth.

One round of showjumping from 09:00 BST will decide the team medals, before the leading individual contenders jump again at 12:45.

Great Britain last won eventing team gold 49 years ago in Munich, while only two riders - Richard Meade (1972) and Leslie Law (2004) - have tasted individual glory.

Today could be a landmark day...

It just fell apart at the end for Britain.

It was a very ambitious start to go so far up so quickly, there was a price to be paid. It was courageous, but they blew it apart in the last kilometre there.

They are capable, though, of taking gold. It's strategy that let them down there, not physiology. That's what we've seen here.

Olympic cycling gold medalist on BBC Radio 5 Live

In the last couple of laps there, the team slightly came apart. There is room for improvement which is a good thing. It wasn't a perfect ride which means there are opportunities to get those time fractions back.

Great Britain slow slightly and slip out of Germany's world record pace, it's a bit of a scrappy finish but the GB team hold out to finish second in qualifying in 4:09.022.

That is quicker than the world record they held before it was broken earlier.

They will race against the USA in the first round. The medal hunt is on...

There is no sign of weakness yet, the four riders are still looking very strong and very close together.

This is fast. Now have the British quartet got the legs to see a new world record home?

They held that record until about half an hour ago. They are almost a second up...

Chris Boardman
Olympic cycling champion on BBC TV

Half a second ahead of Germany already is absolutely enormous. It's a very, very quick start.

Olympic cycling gold medalist on BBC Radio 5 Live

At the moment it is coming down at a tenth a second every lap, they are looking very smooth together.

Ferocious start from the Great Britain team and they hit the first split under Germany's new world-record time.

The all-time leading international goalscorer Christine Sinclair will captain Canada in their women's football semi-final with the USA.

Manchester City's Janine Beckie and Chelsea's Jessie Fleming also start.

Rose Lavelle, Tobin Heath and Alex Morgan start for the USA. Megan Rapinoe, Sam Mewis and Christen Press are on the bench.

And finally it's the turn of Team GB.

Katie Archibald, Elinor Barker, Josie Knight and Laura Kenny make up the quartet.

Go, go, go!

Right then, after Germany's monster ride earlier, how will the USA respond?

We're talking about taking "as-was" world records now... as in, was the world record 20 minutes ago. The Germans have since lowered that mark by almost three seconds.

It's 4:10.138 for the Americans and that would have been a world record earlier today!

BBC Radio 5 Live

Great Britain's most decorated female Olympian Charlotte Dujardin on BBC Radio 5 Live: "It feels great to be back, we competed on the Wednesday and flew home Thursday morning, it is great to be home to see friends and family, and catch up with everyone to celebrate.

"It is so surreal [to be called Britain's most decorated female Olympian], I just feel so proud. I didn't even think it was going to be possible going into the Olympics with a new horse, an inexperienced horse. With the pandemic with the last couple of years, it has been hard to compete, so he went there with very little experience. What he pulled off for me was incredible.

"I think we had an incredible team, to work alongside such incredible people made the game very special."
