There's been a GB gold rush, that's what..

• GOLD 1 - 03:16 BST Swimmer Adam Peaty defends 100m breaststroke title
• GOLD 2 - 07:59 Tom Daley and Matty Lee claim diving gold in the 10m synchronised platform
• GOLD 3 - 08:25 Tom Pidcock triumphs in the mountain bike cross-country event
• GOLD 4??? - 13:30 Lauren Williams competes in the taekwondo final against Croatia's Matea Jelic

There was also a silver in the triathlon for Adam Yee.

Elsewhere, Australia's Ariarne Titmus triumphed over five-time Olympic gold medallist Katie Ledecky in the women's 400m freestyle swimming.

And at the age of 13, Japan's Momiji Nishiya made history by winning the first-ever Olympic gold medal in women's street skateboarding.

Great Britain have surged up the medal table this morning...

It's been a good day for Team GB windsurfer Tom Squires, who has soared up the standings from 14th to seventh on day three in Japan.

He followed up his second-placed finish in Monday's first race with 11th and fourth in the following two.

Squires will need to continue that improvement to move into medal contention, however, with a bit of a points gap developing between the top four and the rest of the field.

There'll be no medal for Great Britain's Jamie Murray and Neal Skupski in the men's doubles, as they are out after losing 6-3 6-4 to Japan's Kei Nishikori and Ben McLachlan in the second round.

As we mentioned a little earlier, Britain's Emma Wilson is in early contention for a medal in the women's RS:X windsurfing.

Windsurfing runs in the Wilson family. Her mum, Penny (nee Way), is a former world champion and two-time Olympian in the sport.

Penny used to put Emma and her older brother Dan in a rubber dinghy and tow them behind her, and now her daughter is an Olympian too!

I spoke to them both back in 2019 - check out their story.

From teen dreamer to Olympic champion. Tom Daley's 13-year hunt for gold is complete...

JMay: Swim; Win; Repeaty!

Ben Stone: Who says Monday mornings are bad? Three brilliant gold medals for Team GB. Hopefully, there's more to come.

Nick Hope spoke to Olympic champion Matty Lee after his diving gold earlier: "All year I've been thinking about the gold Olympic medal and also trying not to think about it because you've got to go through the process.

"But to be able to share my first Olympics with Tom and to be apart of it is just special."

How does that feel? Tom Daley's wait for an Olympic gold is over, at the fourth attempt and 13 years after his first Games, while Matty Lee has made it a debut to remember.

Tom Daley, on partner Matty Lee's Olympic debut gold: "I'm just so proud of you holding that together. I felt I was going to crumble at lots of points in that competition.

"Matty was just in the zone. I've said to Matty all day today, everything's fallen into place and we found that sense of flow. We didn't say all that much to each other. We just knew what we had to do to get the job done."

More from Tom Daley, asked about saying he would quit once he won a gold medal: "I'm definitely going to do the individual competition and then I'll see how my body holds up. They might even introduce Mixed into the Olympics so you'll see me in that."

Nick Hope caught up with Olympic gold diving champion Tom Daley.

"To finally have this gold medal around my neck after so many years!

"I've been diving now for 20 years, it's my fourth Olympic games and lots of people probably would have counted me out of this Olympics being the older person. But I'm in the best shape both physically and mentally and with the support of Matty coming into this competition.

"We've had an unstoppable mentality this year and that's the first time I've ever been able to think like that - that we are the ones to come and beat! I still honestly can't believe what's happening.

"I was gone, I couldn't even sing - I was blubbering!"

Have a feeling you may be seeing this image splashed across a few newspapers tomorrow. Iconic.

Alison Young's hopes of claiming a medal at her third Olympics have suffered a bit of a blow after another up-and-down day.

The 34-year-old Brit has posted finishes of ninth and 20th in Monday's two races - after efforts of eighth and 24th yesterday.

With six races and then the medal race remaining, she sits 15th overall - while Ireland's Rio 2016 silver medallist Annalise Murphy is well down in 32nd position.

Tom Jennings: Today has so far provided further evidence of my completely unbiased theory that everyone called Tom is basically a legend…

Tom Shorey: Greatest ever morning for Tom's?

Are there any other Toms out there making history this morning?

If you hadn't heard of him before today, you certainly have now!

The union jack flag flying high for Tom Pidcock.

Great Britain's third gold medal winner, Thomas Pidcock, is the first Briton to win an Olympic medal of any kind in mountain biking. Britain's previous best finish was a fifth place by Liam Killen at Athens 2004. Pidcock is also the youngest Olympic champion in mountain bike. He will celebrate his 22nd birthday on Friday and breaks the record set by Sweden's Jenny Rissveds at Rio 2016 by 79 days.
