This is already looking like a pretty long night for Japan. Rosko Specman is a blur of dreadlocks as he sprints through to score under the posts. 

Birtley boxer Pat McCormack is going well in the early stages of his men's light-welterweight preliminary bout with Kazakhstan's Ablaikhan Zhussupov.

Watch here.

That world record could still go tonight as Australia are the final team to go. And they have bossed this event since the last Olympics. On track now, GB's biggest rivals for gold? You bet.

There has been plenty of controversy surrounding the sports taking part in these Games for the first time but former England rugby captain Bill Beaumont is full of praise for the rugby sevens event.

The World Rugby chairman said: "It has just been such a fantastic six days.

"In rugby, we tend to think that we know it all, and you come to events that are far bigger than anything we would normally stage, and to be a part of it has just been fantastic."

Not long now until Great Britain take on Fiji in the gold medal match, scheduled to go at 23:00 BST

Great Britain's Pat McCormack is in the ring at Riocentro Pavilion 6.

He's taking on Ablaikhan Zhussupov of Kazakhstan in the preliminary round of the men's light-welterweight.

Watch it here.

Justin Rose became the first man to hit a hole-in-one at the Olympic Games, earlier.

Speaking afterwards, the 2013 US Open champion, said it was a better feeling than his previous hole-in-one:

"I won a car that time but this is definitely better, better bragging rights. When you are the first to do something no one can take that away from you. That was definitely a cool moment."

Read the report from the men's first round.

So close! Great Britain clock a time of 3:51.943, just three tenths of a second behind their own world record.

They were gunning for that too. They'll be annoyed.

GB's women 1-0 GB's men.

Ominous for Japan. Their only touch was the kick-off, with South Africa cutting through to score under posts. Extras added.

Great Britain are going to comfortably beat Denmark's fastest time so far, now it's all about that world record push. Sir Bradley Wiggins digs in and then drops off the back. Three riders push, three laps to go...

An eight-wheeler, you could barely fit a standard-sized toblerone between each rider as they chop and change position in the train. GB are almost a second ahead but just off world record pace. 

Great Britain are ahead of Denmark's time after the first kilometre. Around world record pace.

While GB go round and round, we'll remind you that Great Britain meet Fiji in the final of the rugby sevens at 23:00. Before that, Japan meet South Africa in the bronze-medal match right now.

And Great Britain are under way. Slick, sleek, sprightly, sound.

Great Britain up next. I repeat, Great Britain up next.

No pressure, but just entirely for your info, the current WR in the men’s team pursuit is 3:51:659.

Set by Great Britain (Ed Clancy, Steven Burke, Peter Kennaugh and Geraint Thomas) in gold-medal final at London 2012.

It is defeat for Chris and Gabby Adcock in their mixed doubles opener. 

The Commonwealth Games gold medalists are fancied as GB's best badminton medal hopes in Rio but they lost 13-21 22-20 21-15.

They're not out of the competition however. They have two matches remaining in their group with the top two progressing.

Gold for Simone

Every now and again an athlete's performance truly astonishes, takes the breath away. Simone Biles wows on the floor - she only needed 13.833 to secure gold but was awarded a magnificent 15.933. 

The 19-year-old finished two points ahead of her nearest challenger, and in a sport which is usually separated by tenths or hundredths that's like Usain Bolt winning the 100m Olympic title by 30m or so (which he has done in the past, of course). 

Spectators gasped as she finished her routine, not quite believing the gymnastic genius they had just seen. If I see nothing else in Rio, I can go home happy.

Andy Murray is back out for his second match of the day, this time partnering Heather Watson. They're facing Spain's Carla Suarez Navarro and David Ferrer, and they've snaffled the opening game, thanks to a superb Murray ace.

Watch the best rallies as Great Britain's Johanna Konta loses her women's singles quarter-final with Angelique Kerber of Germany.

I think GB are going to break the world record and it could be by some margin.
