British biathlete Amanda Lightfoot, external: Another great training session completed. I'm super excited for Friday's 15km Individual race.

If you head to our Winter Olympics index, you will see all the lovely live streams that are coming your way this afternoon. Soon is the men's speed skating 1000m, followed by the fascinating spectacle that is doubles luge. Later on, the GB men's curlers take on Switzerland.

Great Britain's only medal winner so far - Jenny Jones - is enjoying some downtime.

She tweets:, external "Enjoying a wee 'bronzing' moment in the sun with team mate Ben Kilner."

It may lack the thrills and spills of short track speed skating, but the longer discipline is the purer test of speed.

In individual races, skaters race in separate lanes against the clock - not each other - on a 400m oval.

All events are skated once, apart from the 500m, which is skated twice. The team pursuit follows a knockout format.

The men's speed skating 1000m gets under way at 13:55 GMT and American Shani Davis will be looking to make history. He's seeking to complete what has been dubbed the "three-peat."

In a nutshell, Davis took gold over the distance in both the 2006 and 2010 Games, so victory would see him become the first male speed skater to win the same event at three successive games.

He won't get it all his own way in the Adler Arena though, Kazakhstan's Denis Kuzin is also a fancy and could win his country's first ever speed skating medal.

Australia's reigning champion Torah Bright earlier won her women's halfpipe heat with a score of 93.00 to progress straight to the final along with Hannah Teter and Xuetong Cai.

They'll be joined by Kelly Clark, who won her fourth consecutive Winter X Games halfpipe gold in January, who topped her heat earlier today, Queralt Castellet and Sophie Rodriguez.

The six riders who finish between fourth and ninth in each heat go into the semi-final. That takes place at 15:00 GMT, ahead of the final at 17:30.

Question. Where do Australians learn to snowboard?

Believe it or not, there's only one bit of live action going on in Sochi right now. It's a good un, though. A grudge match, if you will. In women's ice hockey, neighbours and fierce rivals Canada and the United States are goalless at the end of the first period.

Tonight's menu is a smorgasbord of Lycra, helmets, visors and men in close proximity. Not a Kylie video it's double luge.

After that defeat, Great Britain are down in seventh in the group table. They play China early tomorrow morning. The GB men, by the way, play Switzerland later today.

Matthew Vernon:, external Oh Eve. Why didn't you take the two and go to a final end? You just threw away a massive match in the context of this competition.

James Docherty:, external Remember Canada would have the hammer in the 11th end. Risk didn't pay off, but that's life.

Jack Walker:, external Damn it Canada, still reckon GB ladies can make the semis as their two losses were from the finalists four years ago so nothing to worry about.

So what does it all mean? There's still a long way to go in this curling competition - Britain have played only three on their nine group matches. Their defeats have come to defending champions Sweden and the 2010 runners-up Canada. There's still time to get inside the top four of the 10-team group and make the semi-finals.

#ComeOnTeamGB, external: Should have tied it up. Oh well. Great match altogether. Still confident we'll go through.

Karl Seed, external: It was an all or nothing shot, and it didn't pay off. Canada win 9-6. Unlucky Girls

Michael Ashley, external: Why, oh why did Eve not play a simple draw to tie it up and take into an extra end.

Confused as to why Muirhead went for that shot? You're not alone. To reiterate, Muirhead simply had to slide her final stone near the unguarded centre for two points but, with a third GB stone in play, moving the three Canadian stones at the top-left of the scoring area would have given Britain victory. She failed, and tasted defeat for the second time in three matches.

Germany's Eric Frenzel wins gold in the nordic combined individual normal hill event.

Frenzel, 25, held a six-second advantage after the ski jump phase before the 10km cross-country race.

He won a team bronze in Vancouver 2010, but took individual gold in Sochi after holding off a challenge from Japan's Akito Watabe, who claimed silver. Norway's Magnus Krog came third with Italy's Alessandro Pittin, a bronze medallist four years ago, in fourth.

"An all or nothing shot has given the match to Canada. Eve Muirhead went for the big shot, a high risk strategy taken but it is the Canadians who come out on top. Mistakes from both sides but Canada get eth win and it's three wins for them. GB have only won one."

Can you believe this? Great Britain have lost on the very last stone. Eve Muirhead could have opted for the simplicity of one point and the extra end, but instead wanted to blast away three Canadian stones in order to win the match outright. The high-risk strategy failed, and Canada are victorious.

"An apology from Jennifer Jones, not for the first time. A straightforward shot for Eve Muirhead."

"Haaarrrrdddd" yells Jones. Contact with the first GB stone - will it move the other? Contact...but not enough. GB have one stone for the extra end. But can Muirhead move those three red Canadian stones on the left? Here we go...

One GB stone in the house, Muirhead with two in hand. She needs two in the scoring area, but far enough apart so there's no chance of a Canadian double. Has it gone far enough? I'm not sure. Jones has a chance to blast both GB stones away, which would end the match.

Canada skip Jennifer Jones. Looking for the smash. Got it right this time - two GB stones pushed out of the house. She punches the air. Game-changer.
