"Great to see real people here in the Olympic Park and enjoying the sunshine."

We're almost at speed skating o'clock out in Sochi. There will be 13 heats, with 26 competitors from 14 nations whizzing round in pairs and the big guns going in the final rounds. The winner will be the person with the fastest time, simple as that.

US skier Bode Miller is talking up the dangers faced by the downhillers going for gold on Sunday morning.

"It's very treacherous," he says. "This course has teeth everywhere. The top is aggressive and speeds are so high and the turns are so swingy and bumpy that you can hook an edge anywhere. If you are not totally focused and paying attention, this course can kill you."

"Finnish goalie Noora Raty admitted her team had a "nightmare start" when they went a goal down to the United States within 60 seconds of today's Olympic ice hockey opener starting.

"Raty did her best to hold back the tide despite getting clobbered in the neck at one point during the game, and the 3-1 final score does not reflect too badly on Finland, given the clear supremacy of the US and Canada in women's hockey.

"They got a few lucky bounces, but they definitely earned their luck today - they were the better team," Raty told reporters afterwards. Her team-mate Mira Jalosuo called the second and third US goals "lucky bounces".

Russian fans brighten up the Olympic Park in Sochi on the first day of competition. I just hope the person who took this photo was wearing shades!

Who can challenge speed skating king Kramer then? His closest rival is likely to be his compatriot Jorrit Bergsma, a 28-year-old making his Olympic debut. He is the only man other Kramer to win a long distance World Cup race this season - he won the 5,000m contest in Berlin, an event Kramer skipped.

Enjoying the action so far? Hungry for more? Next up it's speed skating - the men's 5,000m takes place at the 8,000-capacity Adler Arena, which reportedly cost about £20m to build. And if ever the winner of an event can be deemed a foregone conclusion then this is it. Sven Kramer of the Netherlands is world record holder in the 5000m, 10,000m and team pursuit, and unbeaten over those three events in the 2013-14 World Cup season.

If you are just joining us, here's a quick recap on what has happened so far. Sage Kotsenburg won the first gold medal of the Games in the men's slopestyle snowboarding, with Britons Jamie Nicholls and Billy Morgan in sixth and 10th respectively. Norway's Marit Bjoergen stormed to her fourth Olympic gold in the women's 15km skiathlon, and the USA beat Finland 3-1 in the women's ice hockey.

Oh, and away from the snow and ice, American bobsledder Jonny Quinn got trapped in the bathroom of his dodgy hotel room and had to smash his way out. Anyone got a similar tale to tell - send it to us via #bbcsochi on Twitter or text to 81111.

"That little burst from Charlotte Kalla was costly as there was still over 1m to go. Marit Bjoergen tactically got it all right. She has added another gold and must surely go down as one of the greatest Olympians of all time."

A brilliant sprint finish from the "Iron Lady" of cross-country skiing sees off the challenge of Charlotte Kalla. Marit Bjoergen of Norway collapses in a mixture of exhaustion and joy as she crosses the line to pick up the fourth Olympic gold of her career. Heidi Weng of Norway takes the bronze.

I'm not going to lie to you, this looks absolutely knackering. The leaders are currently skiing uphill as they reach the end of the 15km course. Charlotte Kalla of Sweden and Marit Bjoergen are now fighting it out for gold...

After finishing 10th in the snowboard slopestyle final, Billy Morgan poses with GB team-mates Katie Summerhayes, Rowan Cheshire and Emma Lonsdale.

We're at the business end of the women's skiathlon. Finland's Aino-Kaisa Saarinen leads followed by Norweigan duo Therese Johaug and Heidi Weng. They are at the front of a group of five skiers who have broken ahead of the field.

Slopestyle winner Sage Kotsenburg (USA) said: "I'm really excited. It feels awesome. I don't know what to call it. I have no idea what's actually going on. This is the craziest thing that ever happened."

The skiathlon involves a split between two skiing techniques: classic, which involves skiing along pre-set parallel tracks, and freestyle, which closely resembles the motions of ice skating, with 7.5km of each. We've put together a text and video guide to the sport.

More on American bobsledder Johnny Quinn's nightmare ordeal. After finding himself trapped in his hotel bathroom, he drew on his bobsled experience to smash a hole in the door and force his way out.

The Sochi Games have had various problems with the provision and build quality of accommodation for athletes and journalists attending the Olympics. Reporters arriving in Sochi over recent weeks have documented unusual 'twin' toilet installations, unfinished hotels and problems with water and electricity supply.

"It's a bit more sedate at the Ice Cube on the Olympic Park where GB's Eve Muirhead and her curling team have been training. The reigning Olympic champions Sweden were also on the ice. The two rinks meet In their first round robin match on Monday. Keeping a close eye on things was Rhona Howie, who won the gold in Salt Lake City in 2002. She's now Muirhead's coach."
