Therese Johaug is through the 10km mark in just over 30 minutes and has extended her lead over Frida Karlsson to 26 seconds.

Karlsson is also being reeled in by a chasing pack behind her - silver and bronze are up for grabs here.

They will switch to freestyle skiing and it is a completely different technique.

Therese Johaug puts on the afterburners and powers into the lead - there's a 15 second gap now back to Frida Karlsson in second.

Is the first gold of the games heading to Norway?

Look at the pack that we have now.

You are starting to see athletes getting stripped away from that as the pack of four come down for the change.

Time for a pit stop and Therese Johaug is out first as we switch to freestyle skiing.

Krista Parmakoski, Kerttu Niskanen and Frida Karlsson follow with an eight second gap now between the leading four and the chasing pack.

The USA's Jessie Diggins was well fancied but has some work to do if she is to fight her way back into contention.

You are seeing athletes struggling with the altitude and a really tough course.

It is a big wide course, so it is easy to over-take, but this is the first time that any of these athletes will have competed here for real.

But everyone you would expect to be contending for it, is still in it.

Thanks Harry.

We are 20 minutes in and three-time world champion Therese Johaug of Norway is leading a breakaway pack of four. Sweden's Frida Karlsson is also there, sandwiched between the Finnish pair of Krista Parmakoski and Kerttu Niskanen.

But next, the first gold of the Games will be won in the women's skiathlon.

Thomas Mallows is going to guide you through that one.

Thanks for your company to those who made it through the night!

Good morning to all those just joining us.

Where have you been?! The opening day of the 2022 Winter Olympics is already well under way.

Anyway, to bring you up to speed, Katie Ormerod made her long-awaited Olympic debut earlier this morning - however she was unable to secure a place in the final. Check this out...

GB are third after the latest round of matches, following their 8-3 win over Czech Republic.

They're behind unbeaten Italy, who they face next from 12:05 GMT, and Sweden, who have played two games more.

Canada and USA are hot on their heels, tied fourth.

Skiathlon. Wow. You can feel how much it burns just watching, can't you?

It's Finland's Krista Parmakoski at the front after 10 minutes of lung-busting action.

The first gold medal of the Games is on offer in the women's cross country 15km skiathlon.

That event has just got under way - so who is best placed to win it?

This event involves one of the mostly eagerly anticipated duels of the Olympics, from a Scandinavian perspective at least.

Norway's Therese Johaug and Sweden's Frida Karlsson are set to go head-to-head, however the USA's Jessie Diggins is another to watch out for.

Here's what GB's mixed curling pair Bruce Mouat and Jen Dodds had to say after their latest win.

"It was a great game - our best game by far," said Mouat, who confirmed he will continue to wear his lucky hat after another win.

Dodds added: "We had a really good practice again and that showed - we controlled the angles and once we got that lead we were able this time to hold it. We're quite a resilient team."

On facing Italy later this evening, Dodds said: "Every game we've been building a lot of confidence. Italy will come out firing and they're a really strong team."

That victory leaves GB in a great position as they look to seal a spot in the medal matches.

They face unbeaten Italy from midday today, and they'll be full of confidence following that win.

Italy are currently 7-3 up against Australia, while USA lead China 7-5. Sweden have sealed a 6-2 win over Canada to further boost their hopes of finishing in the top four too.

That will give them great confidence in going into this evening's game against Italy. I am pleased to see them talking.

Coach must be happy with how they are playing at the moment.

All power to GB and what a great week we're having.

Nicely done and it's just enough for GB to get their two - and the match is over.

They came out all guns firing. Started well, kept building and at seven ends, find themselves 8-3 up.

Four wins, just the one defeat.

Smashed it!

Bruce Mouat sweeps GB's final stone cleanly onto the red and that's enough for the Czech Republic!

After seven ends, with the score at 8-3, they concede the match. That's a great win for Dodds and Mouat.

Steve Cram
Curling commentator on BBC TV

It is a power-play and you want to score as much as you can, but even a one would give the Czech Republic a lot to do.

A final chance for Zuzana Paulova to affect the outcome of this end, a crucial one for the Czech pair you sense.

That's not what they wanted though. The attempted guard curls too much and Jen Dodds will have a good look at this.
