Former world-champion hurdler Jana Pittman has become the first Australian woman to ever compete in both the Summer and Winter Olympics.
Competing in the women's-bobsleigh team event, she and team-mate Astrid Radjenovic had hoped for a top ten finish at Sochi but they had to settle for 14th.
Pittman told Channel 10 it has been tough competing against the Northern Hemisphere's best, but says the two have been able to motivate each other during the more difficult times.
"We always do. That's kind of, I guess, the beauty of our friendship as well, that it doesn't matter what we go through, we're always in it together. So I'm very grateful. She's taken me to my first Winter Olympics, and I think it's been fantastic."
Pittman says she is uncertain whether she will attempt to qualify for another Winter or Summer Olympics.
The other Summer Olympian to compete in the bobsleigh at Sochi was a former silver medallist at the 2004 Athens Games and a gold medallist at the 2012 London Games.
The United States' Lauryn Williams won those medals in sprint events but, on Day 12, she won a silver in the bobsleigh with Elana Meyers as the USA 1 team.
Williams is only the third woman to have won medals in both the Summer and Winter Olympics.
She and Meyers finished behind the Canada 1 team of Kaillie Humphries and Heather Moyse, who defended their title from Vancouver four years ago.
USA 2 won the bronze.
"Oh, wow, and that look says it all. She's come here for one thing and one thing only, and it's a gold medal, and she knows it's going to be an uphill struggle now ... Okay, Kim's score, 74.92. Where will Lipnitskaya be? And it's going to be third place, 65.23. She's a fair way off the pace, it has to be said."
That's Channel 10's call of 15 year-old Russian Yulia Lipnitskaya's short program in the ladies' figure skating in Sochi.
The short program is vital for competitors' hopes to qualify for the free program the following day.
Scores from both the short and free program are combined for the overall result and the awarding of medals.
Lipnitskaya helped Russia to a gold medal in the team event earlier in the Games and carried many of the Russian hopes for another gold on her young shoulders.
But her fifth place in the short program seems sure to make that almost impossible.
Reigning Olympic champion Yuna Kim, of South Korea, leads after the short program, but another Russian, Adelina Sotnikova, surprised many by qualifying second.
"Here we go. 74.92 is Kim's score. It's going to be close to that. It's got to be close to that. Hang on ... 74.64. A massive score for Adelina Sotnikova. She cannot believe it. She has blown her personal best out of the water by nearly four points. Absolutely unbelievable. Great to see the judges have gone with it. She's into second place."
Australia's Brooklee Han qualified for the free progam in 22nd place.
Norwegian biathlon legend Ole Einar Bjoerndalen has become the most successful Winter Olympian ever with a record 13th medal.
His gold in the mixed relay at Sochi means the 40 year-old has now won more medals at Winter Olympics than anyone else.
Eight gold medals are among his career haul.
One of those golds came in the sprint event at Sochi, and another can be added in the men's relay on Saturday.
The Czech Republic won the silver medal in the mixed relay, and the Italians took the bronze.
Russia's men's ice-hockey team has left its fans disgruntled after crashing to a 3-1 defeat to Finland in the quarter-finals.
Finland now plays Sweden in one semi-final, while defending champion Canada plays the United States in the other.
It was a second successive Olympic Games loss in the last-eight stage for Russia, whose players were booed off the rink by their disappointed fans.
This teary fan summed up the feelings of some home supporters.
"I just don't have any words right now. This was a home Olympics. We didn't have the right to make a mistake. We made a mistake."
In other events, United States ski star Ted Ligety won the second Olympic gold of his career with a victory in the giant slalom.
Frenchmen Steve Missillier and Alexis Pinturault finished second and third, respectively.
And Czech skater Martina Sablikova has repeated her 5,000-metre speed-skating gold medal from Vancouver four years ago in Sochi.
Dutch skater Ireen Wust was second, and teammate, Carien Kleibeuker, third.
