Russia ensured top spot in the medals table at the Sochi Winter Olympics after sweeping the podium in the men's 50km cross-country freestyle.
Alexander Legkov took gold for the host nation while compatriots Maxim Vylegzhanin and Ilia Chernousov took silver and bronze respectively.
Russia went into the event level on Norway with 11 golds, but the victory puts them ahead with Norway having no chance of any medals in the two remaining events on the last day of the Games.
Russia later also took the honours in the four-man bobsleigh, moving their total number of golds to 13.
It was the second medal sweep of the major cross-country endurance events in Sochi after Norway had enjoyed total domination in the women's 30km race on Saturday.
Britain's Andrew Musgrave finished 53rd out of 60, and admitted his Olympic experience had been "pretty rubbish."
Most of the leading contenders stayed together until the final 2km on Sunday until Legkov upped the paced, drawing his two compatriots and Martin Johnsrud Sundby away from the rest.
If Sundby won it would have put Norway clear at the top of the medals table, but he finished off the podium completely as the three Russians dominated the sprint for the line.
Musgrave trailed in 10 minutes and 13.7 seconds behind the winner, though the Scot had been battling illness ahead of the race and his one aim had been to finish the race.
He was left to reflect on a better performance in the sprint, where he became the first Briton to reach the quarter-finals.
Musgrave had entered the Games tipped as medal contender after his astonishing triumph in the Norwegian national championships.
His victory last month caused a sensation in Norway, but he has come back down to earth with a bump in Sochi.
"It's been pretty rubbish. I don't know what I've done, I've just skied rubbish. I'm pretty disappointed," he said.
"Today wasn't right; when I wasn't feeling great I wasn't expecting that much - it was the sprint that was the biggest disappointment."
He followed up his quarter-finals appearance in the sprint with a 44th-placed finish in the 15km classic, while he had to pull out of the team sprint after partner Andrew Young's pre-existing heart condition flared up.
Musgrave was hoping to end his Olympics on a high note but was struck down by a fever and sore throat in the night.
"Every time I come through I seem to have a new excuse but I felt terrible this morning," he said.
"I was like 'whatever, I may as well race. It's only the Olympics once every four years, maybe it'll go well. Tour de France guys race with broken collarbones and I've got a little bit of a cold and sore throat, so I may as well just go'.
"At the start, I was just thinking I would stay at the back of the pack and not really do any work and see how it went, but I didn't go very fast for the first lap and I was just hanging on after we'd done one lap.
"But I wasn't feeling so good and I just had to ease up and go at a pace that I could keep until the finish.
"After that I did four even laps - not very fast at all. It's not really good but whatever. I got to the finish, that was all I could really expect."
His next big competition will be the World Championship in Guiyang, China, next year.
"I'm glad we do have a World Championship next year, it gives me something to focus on after a little bit of a disappointment here," he added.
