Megan Oldham is up and walking, albeit gingerly.

She had put down a brilliant run until that final jump and she gets a score of 38.70.

The Canadian is still in third though with her first run of 69.76.

Megan Oldham is on her feet and walking away.

Ooooh. Let's hope Megan Oldham is OK.

The Canadian takes a huge tumble as she tries to land her last jump. It was all going so well until then.

Five riders have completed their second runs, but none of them have managed to better Eileen Gu or Mathilde Gremaud's scores, or even push Megan Oldham out of the bronze-medal position.

Here comes the Canadian...

BBC Sport's Sarah Dawkins has spoken to a couple who have driven to Livigno all the way from Stratford-upon-Avon in their campervan.

Bee and Nick Savage are there to watch Kirsty Muir and Mia Brookes today and this is what they had to say:

“We’ve driven all the way from Stratford-upon-Avon in our camper van over six days to get here. Totally worth it to cheer on our girl [Kirsty Muir].

"We’re here for 10 days, we’ve got tickets for six events and then it will take another 10 days to drive slowly home.

"It was -16 last night but we have got good heating on board, electric blankets and everything else you could possibly imagine to keep warm. It’s the first time we’ve done ths but we’re thinking doing it again in four years.

"We want to see a gold medal for Britain. Any medal is good, gold is best.

"We’re very very patriotic. And we’re just mad."

So scores on the doors after the first run...

GOLD - Eileen Gu (Chi) - 86.58

SILVER - Mathilde Gremaud (SUI) - 83.60

BRONZE - Megan Oldham (Can) - 69.76

But that's far from final...

GB's Kirsty Muir sits in 10th and will be hoping to squeeze into that top three with her remaining two runs.

I think the Chinese fans are the loudest here so far. Eileen Gu is their absolute hero and they couldn’t hide their delight when Switzerland’s Mathilde Gremaud scored fewer points to keep Gu top after the first run.

Plenty of work for Kirsty Muir to do, but plenty of time to do it.

We've got a battle on our hands now, the gloves are off. Huge, huge run.

The tube was the one chink in Gremaud's armour but clean doubles all the way through.

Another big, big run.

Eileen Gu and Mathilde Gremaud are setting the standard in Livigno.

A score of 83.60 moves the Swiss skier into second - more than 10 points clear of Megan Oldham in the bronze-medal position.

That is a big, big run for Eileen Gu. That will put a lot of pressure on her three closest rivals - Megan Oldham, Kirsty Muir and Mathilde Gremaud. That feels like the battle - four women, three medals.

What a run from Eileen Gu.

"YES," she shouts. The Chinese skier is delighted with that.

It's HUGE. A score of 86.58 puts her miles in front.

Defending Olympic champion Mathilde Gremaud is up next.

That run was beautiful, so. so good up to the last point. That is a foundation of a very big run there.

Kirsty's absolutely devo'd, you can see the look on her face.

A 37.15 leaves Team GB's Kirsty Muir second from bottom after the first run, with two skiers left to go.

But remember, it's only the best run out of three that counts.

Room to improve for the Scot.

Oh no! Kirsty Muir was brilliant through the first rail section but she can't quite land her penultimate jump.

Let's see what score she gets for that...

So far, so good from Kirsty Muir...

Here she is! Team GB's Kirsty Muir.

What can she put down on this first run?

Off she goes...
