James Guy, like the rest of GB's swimming team, enjoyed a sensational meet in Tokyo, securing gold in the 4×200 metres men’s freestyle and the 4x100m mixed medley relay.

He came home to a very proud dad.

Dina Asher-Smith returned and GB's relay team breezed into tomorrow's 4x100m relay final by winning the heat.

Watch how they did it below.

A big dive by Lois Toulson in round three as she scores 67.20 and is back into the qualification places - 10th as things stand. Much needed.

A 57.40 for Andrea Spendolini Sirieix but she remains very well placed in seventh.

Steven: 46 year old Dallas Oberholzer showing that age is nothing but a number with his skateboarding skills.

Jason: I'm really enjoying the Olympic coverage of the skateboarding. Are there any other sports where 12 year olds & 46 years olds compete in the same discipline? So much talent and everyone smiling/supporting each other.

Dallas Obaholzer brings it home. He's out there doing it for all of the dads who roll round concrete bowls on Sunday mornings, for the rad-dads.

Yes Dallas, I'm feeling you. So he will bring up the rear with that score, but he can say he's been to the Olympics as a skateboarder.

We are already into the mid-80's - and I'm not talking about the temperature. Some of the biggest names have not made it through.

Take a breath, this is spectacular. It's delivering on all counts.

Is the skateboarding the most good-spirited event at the Olympics? We saw the great camaraderie among the youngsters in the women's park final yesterday and it has been the same in these men's prelims today, everyone quick to congratulate each other after their run.

A monster score of 84.31 has Luiz Francisco of Brazil top of the third prelim and into the final.

Another near perfect dive by China's Quan Hongchan as she scores 94.40 in round two.

The top 12 go through and Andrea Spendolini Sirieix is well placed in sixth but Lois Toulson has slipped out of the qualification places and is currently 15th.

Ryan: Going to have to boot up Tony Hawks Pro Skater tomorrow, the skateboarding is making me miss it!

Steven: That clip of the cameraman being taken out by Kieran Woolley is going to live forever on YouTube.

Francesca: Hahahah he took out the cameraman… but the guy is like I’m still recording.

Hector Pardoe was the first bit of British interest we had in action this morning. Unfortunately his hopes in the 10km swim were ended by a stray elbow.

GB's 4x100m relay team on BBC One:

Asha Philip: "It was an early start for all of us, we were on a 6:40am bus, breakfast at 6am and it was a stretch, but we knew we had a job to do so the time didn't really matter. We came out here to work, get a good time and get a good position for the final. We executed the race and we did well."

Imani-Lara Lansiquot: "It's been really inspirational, seeing how these girls have done in the individuals just spurred me on to want to put down a really good leg for them. I fully, fully have true belief and trust in all of us. It's been a crazy 18 months but I know we can bring it home."

Dina Asher-Smith: "There was never any doubt in my mind that I'd be lining up here today because the relay's really important, we got a bronze medal in Rio. These ladies are in great shape, they're incredibly talented, so I knew I had to rest up and get ready for the team event. I've been training hard to get ready."

Daryll Neita: "I was watching the first change on the screen thinking, 'ok, that was really good,' then I saw Imani running and by the time she's running I just get my head down. I saw Dina coming into it and I thought, 'it's go-time.'

"I really wanted to bring it to the finish for these girls. We've worked so hard. We haven't had that much practice and neither has the rest of the world in the pandemic.

"To come out here today in the heat and set a British record, to have amazing changes - we've got confidence. Girls, good job!"

A score of 21.68 for Dallas Oberholzer.

At least he didn't hit a cameraman.

The 46-year-old Dallas Oberholzer is up now in the men's park skateboarding prelims.

Go on, Dallas, give those of us who fear our Olympic hopes are over because of our age some hope that the dream could remain alive for a bit longer yet...

Quan Hongchan has just smashed the first round of women's 10m platform with a score of 85.

The Chinese diver is just 14 years old. There is an incredible amount of youngsters doing amazing things at these Olympics.

Watch the moment Liam Heath secured his place in the kayak 200m final.

Rapid stuff all round.

Another nice solid opening dive by GB's Lois Toulson as she scores 67.50 with her first dive. All about doing what is needed to get through to the final.

The diving is live on BBC Red Button now and Andrea Spendolini-Sirieix has just completed a solid first dive, scoring 63.00.

Slightly disappointed I've not seen Tom Daley knitting a snazzy little top for a dog in the crowd again.

Hungary's Tamara Csipes cruises to victory.

GB's Deborah Kerr finished last in that semi-final after a bright start.

Strong performance from Dina Asher-Smith. You can see this team is well-drilled, controlled.

They're highly skilled and they've put a lot of effort into this performance.
