The women's sprint classic quarter-finals are about to begin.

Reigning Olympic champion Joanna Sundling, who finished second in this morning's qualifying, is in the first heat alongside world champion Kristine Stavas Skistad of Norway.

As far as quarter-finals go this is a real treat for us because their rivalry has been labelled 'Battle of the Titans' in the run-up to these Games.

Had Skistad finished in the top three in qualifying then we wouldn't have seen these go head-to-head so soon either.

There are three mixed-team relay quarter-finals about to start at the Milano Ice Skating Arena.

How does it work, I hear you ask?

The best teams in each quarter-final qualify for the semi-finals and the two fastest third placed teams also progress.

Great Britain are not involved in this event.

So here's how things stand after the downhill event...

GOLD - Breezy Johnson (USA) - one minute 36.59 seconds

SILVER - Ariane Raedler (Aut) - one minute 36.65 seconds

BRONZE - Laura Pirovano (Ita) - one minute 36.86 seconds

Their team-mates will race in the slalom at 13:00 GMT to decide who lands a medal.

The incredibly steep moguls course is just over 200m long, and features artificial bumps that the skiers must navigate with tight turns and aerial jumps.

Athletes are judged on their speed, turns and aerial manoeuvres.

There you have it. That's the downhill event done and dusted as Slovakia's Katarina Srobova crosses the finish line - a whopping 10.07 seconds behind leader Breezy Johnson.

Srobova's got a smile on her face, though. She's just happy to be there.

Petra Vlhova is back. We have to talk about her.

I feel unbelievably nervous for her compatriot, a young racer, who's racing downhill - if she doesn't finish and Petra doesn't get the chance to make her come-back...

Petra has had a horrendous time with injury. She went from stratospheric legendary status [as Olympic slalom champion in 2022] to down in the dumps and it took her years to come back.

So we are so happy she's back.

Slovakia's Petra Vlhova is the defending Olympic champion in the women's slalom so she'll be wanting to grab a medal today.

But her team-mate Katarina Srobova is making her Olympic debut today and she only managed a 43rd place in downhill training last week. Off she goes...

I've come to a new venue today, the Livigno Aerials and Moguls Park, for moguls qualification. Given I've done zero exercise since arriving in the mountains a week ago, I decided I would do the commute on foot. What I didn't realise was that most of the half-hour walk was uphill, at nearly 2,000m altitude.

After huffing and puffing my way here, I then had my lunch and the croissant I had just bought confiscated by security.

Today can only get better, surely.

Great Britain's Niall Treacy recorded a time of one minute 54.040 seconds in the men's 1000m heats.

That was the slowest time of his heat meaning he has not advanced through to the quarter-finals.

Kazuki Yoshinaga of Japan crossed the line in one 25.944 seconds, with Clayton DeClemente of the United States less than a second behind him.

BBC Sport reporter Emma Smith is at the arena and will bring us more shortly ...

Breezy Johnson had to fight today.

There were quite a lot of mistakes and errors in there - maybe because she's paired with Mikaela Shiffrin she wanted to be even better but 110% in sport doesn't exist, it means you start making mistakes. 100% of Breezy Johnson is the best.

Only five skiers left to go and Breezy Johnson remains firmly in the lead.

If her and Mikaela Shiffrin weren't the favourites before the downhill, they certainly are now.

The two best athletes in each heat automatically qualify for the quarter-finals, while the fourth fastest third-placed athletes also qualify.

GB's Niall Treacey will take to the ice next ...

Great Britain's Niall Treacy is in the men's 1000m short track speed skating heats.

He is in the fourth group with Canda's Steven Dubois, Clayton DeClemente of the United States and Kazuki Yoshinaga of Japan.

We'll let you know how he gets on.

The USA are so far ahead as favourites in this competition but the competition for the medal placings is going to be intense, because this is a really tight race - the top 10 so far decided by 1.16.

Ah that's a shame. It's the same gate that caught Lindsey Vonn out on Sunday and Isabella Wright hits it here.

While she doesn't go down like Vonn did, she knows that's enough to of a setback to harm any medal hopes and she doesn't finish her run.

The heats for the women's short track 500m speed skating have finished and we have our 20 quarter-finalists.

The four quarter-finals take place on Thursday evening.

In those races, the two best athletes in each quarter-final qualify, and the two fastest 3rd placed athletes also qualify for the semi-finals.

Not quite as quick as her gold medal run from Sunday but Johnson will hand to Mikaela Shiffrin who will currently go last in slalom.

Not quite as lean, a couple of errors, but still good enough to lead.

If Breezy Johnson manages to win another medal today, she'll be hoping it holds up better than her downhill one...

Breezy Johnson is into the lead! The American's one minute 36.59 seconds is the fastest time so far.

It's a tad slower than her winning downhill run on Sunday, but that will give Mikaela Shiffrin the perfect chance to finish the job and get the pair on the podium.
