Sky Brown races over to embrace Lola Tambling at the end of an fine opening run.

She almost goes down twice but shows her guts to stay afloat and nudge herself up to 73 points.

That puts her in the top eight for now - and is a great platform to build from.

Australian sensation Arisa Trew looks fantastic for 40 seconds of her first run but then comes crashing down on her final trick.

She scored 72 points even with a fall!

With the women's park qualifying having a very young field of athletes, how old you have to be to take part at the Olympics?

The ruling from the IOC, states: "There is no specific age limit for taking part in the Olympic Games. This depends on each International Sports Federation and the rules it lays down for its sport."

Huge cheers for Sky Brown as she's introduced to the crowd.

There's a giant "let's go!" from Lola Tambling too as the camera pans past.

This is one stacked heat.

If you remember watching in Tokyo, you may be wondering why the scoring seems so much higher now.

That is because the system for each trick has changed, being marked from 0 to 100 now instead of 0 to 10.

In 2021, Sky Brown won bronze with a highest score of 56.47. This year, she would not get anywhere near qualifying with that.

Park skateboarding takes place on a course - like those seen at local skate parks - with ramps, bends and ridges.

The skaters are split into four heats of five or six skaters, as determined by a random draw. They each perform three 45-second runs. Everyone does a first run in turn, then a second etc.

The top eight scorers overall progress to the final, where they repeat the process.

In the event of a tie, the skater with the higher score from their second-best run wins. If still tied the judges vote electronically on who should be ranked first. The head judge breaks a tie in the final results and rankings.

She might not be 100% but Sky Brown is still full of the bouncy confidence that so endeared her to the British public when she won bronze at Tokyo.

Speaking to Newsround, she described her dislocated shoulder injury as "scary" and said that she'll wear a brace while skating but accepted that injury is part of being an Olympic athlete.

"There is this side of it too - [you] can’t let some fall or pain stop you from what you want to do," she said.

"I am strong and I believe in myself and I hope it inspires."

Earlier on Tuesday, Sky Brown posted on Instagram , externalthat she was "not 100%" but has promised to give it "1000%".

"After this I will have to go and have surgery on my shoulder," she wrote. "So with this shoulder and my knee injury, unfortunately I am not 100%. As I wish I could’ve been for this contest.

"But, it’s ok… I’m here, I’m alive, and I’m a skateboarder. and I WILL give it my 1000% today.

"This for my country, for my friends and for my family. This is for the people I love and for EVERY single little girl that is watching me!! This is for you guys.

"Be brave, have fun and do cos you freakin LOVE IT!!!"

BBC Sounds

Team GB's Lola Tambling has been skating since the age of seven after her parents built a skate park in her home town of Saltash in Cornwall.

She'll be eyeing a place in the women's park final and does have pedigree at this level. After all, she came sixth at the 2022 World Championships.

BBC Sounds' Grassroots to Glory series caught up with the 16-year-old to find out her story.

We're continuing with the skateboarding on BBC TV - where we're moving to BBC Two during the news - but on the Red Button, we're switching to live men's hockey - world number ones the Netherlands in semi-final action against Spain, the surprise team of the tournament. You can follow that on this page via the Watch and Listen tab.

Here's a look at what's happened so far this morning at the Paris Olympics:

• Team GB fail to add to their equestrian medal haul with Ben Maher and Scott Brash coming up short and Germany's Christian Kukuk winning gold.
• Fellow British rider Harry Charles withdrew prior to the event because his horse was not fit enough to compete.
• Britons Laura Muir and Georgia Bell qualify for the women's 1500m semi-finals, while Victoria Ohuruogu makes it into the women's 400m semis.
• Team GB's Jack Laugher and Jordan Houlden qualify for the men's 3m springboard semi-finals.

And here's what's coming up:

• Britons Sky Brown and Lola Tambling are about to skate in the women's park preliminaries.
• World number ones the Netherlands are under way against surprise package Spain in the men's hockey semi-finals.
• Britain's Andrea Spendolini-Sirieix competes in the women’s diving 10m platform final at 14:00 BST.
• Team GB's Micky Beckett is in sailing medal contention when the men’s ILCA 7 (dinghy) race gets under way at 14:43 BST.

I predicted earlier that scoring over 80 points might be enough to make the final. So far, four have made it into that hallowed ground.

These next four will be looking nervously over their shoulders as Sky Brown, Lola Tambling and company get going shortly:

• 5th: Sakura Yosozumi - 79.70
• 6th: Raicca Ventura - 76.24
• 7th: Lily Stoephasius - 74.40
• 8th: Emilie Alexandre - 73.48

She sent her board into the stratosphere - such a good effort from Pacheco.

Even closer for Brazil's Isadora Pacheco for her biggest trick as her right foot slides off the board as she lands and she crashes to the floor.

Save that trick for the final?

She'll be in fourth place after heat two with 10 skaters left to go.

Fair play to Zheng Haohao, she's come and put on a great show for the crowd. Very fair play.

It's also game over for Zheng Haohao as she comes over the spine of the half pipe but can't land it.

She'll finish with her first round score of 63. Not enough to make the final but she's acquitted herself well.

Tears and generous applause as French athlete Nana Taboulet says goodbye to the skate park.

She's crashed out for the third and final time - and her Olympics is over.

To be fair, I was doing high jump in the back garden when I was 11 with two deckchairs, a cane and a bunch of pillows to land on.

Never made it to the big time though...
