What a mouthwatering array of sport we've already been treated to on the opening day.

Here are Claire Balding and Nick Bright to tell you how you can get involved yourself.......

Welshman Joe Corina will get his campaign underway against Charly Suarez of the Philippines at about 22:00 BST - so any minute now.

He'll be hoping to follow teammate Galal Yafai into the last 16, after Yafai outpointed Cameroon's Simplice Fotsala this afternoon.

You can watch Cordina here.

This is an amazing picture!

It shows American gymnast Ragan Smith and Team USA basketball player DeAndre Jordan stood together. Smith is 4ft6ins tall while Jordan is a towering 6ft11ins.

The women's epee final is currently under way - it will be gold for either Italy or Hungary.

You can watch that here. 

Team GB's Justin Rose has been talking to golf correspondent Iain Carter for a BBC Sport interview. It's safe to say he's loving his Olympic experience so far as he makes his debut on Thursday.

On his first impressions of the Olympics: "The scale of the Olympics is just unbelievable. When you walk around the Olympic Village, you see the amount of athletes roaming around, the scale of the gyms, food hall. It's mind boggling."

On what it would mean to win an Olympic medal? "If I win Olympic gold half of it goes to my wife Kate (she was a European artistic gymnast but her discipline was not in the Games). I certainly feel we are just as worthy of being here as anyone else, anybody who gets to the top of their sport is worthy of their spot in the Olympics. Nothing comes easy here. No-one is gifting you a spot.

On all the nations competing in Rio: "With all the world's issues right now, to see so many countries in one place, just co-existing with a smile on their faces is just great to see."

Golf will make its return to the Olympics for the first time in 112 years when it gets under way on Thursday and Masters winner Danny Willett is packed and ready to go.

Speaking of golf, did you clock Rickie Fowler's haircut during the opening ceremony yesterday? What's he playing at! Looks like Gary Oldman in The Fifth Element.

The sun is setting behind the mountains, fans are walking to and fro around the Olympic Park, some going home, some taking respite before gorging themselves in more sport. Plenty of selfies are being taken, capturing this once-in-a-lifetime moment. The temperature is still snug, but it's cooled down significantly since this afternoon's stifling heat.

China have another bronze medal, as Yiwen Sun takes third spot in the women's individual epee.

Sun beat Lauren Rembi of France 15-13 at Carioca Arena 3.

History was made a little earlier when Vietnamese shooter Vinh Xuan Hoang won gold in the men's 10m air pistol - the first Olympic gold in any sport for Vietnam.

"Making this gold medal is a life memory, never forget this," he said.

"Because (it is the) first time making a gold medal for Vietnam."

Great Britain's Amy Wilson-Hardy: We managed to not concede - that was the main aim and we did it. 

There was first game nerves against the hosts but we got the win we needed then it was about resetting and putting in the performance to make those at home proud. 

We have set ourselves up well now going into the Canada game.

What a half that was for Great Britain, four tries, a much better showing in the early stages than in the victory over Brazil at lunchtime. 

Amy Wilson-Hardy who is a bit of a whizz on the violin I'm told, got things rolling within a minute and set the tempo.

Amy gave the BBC some examples of her basic Portuguese this week and she clearly feels right at home here. 

We have another try as I type, Heather Fisher powers free and touches under the posts. That's 40-0 and there's the whistle. They'll be thrilled with that.

Team GB's women's rugby sevens captain Katy McLean is thrilled that the sport is making its debut at the Games.

That was a very impressive win from Britain, but the important match is against Canada tomorrow, because whoever wins that will stay away from Australia in the next round.

British long jumper Jazmin Sawyers wins the award for spot of the day, maybe even of the Olympics. She's whipped her camera out to snap a dog. On a horse. On. A. Horse!
