Pilot John Jackson and his four-man bobsleigh crew came within 0.11 seconds of crowning Great Britain's best Winter Olympics in 90 years with a medal.
Jackson and team-mates Stuart Benson, Bruce Tasker and Joel Fearon managed to clock a time of 3:41.10, eleven hundredths of a second behind bronze medallists USA 1 at the Sanki Sliding Center above Rosa Khutor on Sunday.
Jackson, Britain's last chance of a medal at Sochi 2014, nailed the second fastest time of the second run to move up three places to an overnight position of seventh, and within touching distance of the leaders.
And despite taking the lead by 0.27 seconds on their final run, they were eventually bumped down by the leading contenders.
"Overall it has been a great race and to only finish 0.11 seconds off the medals is amazing," said Jackson.
"Just being involved in such a great race makes it enjoyable. I would like to stay on for another year depending on what the Royal Navy and Royal Marines say. But I'm happy to keep working with this boys - the future is bright."
Gold again for Zubkov
Alexander Zubkov, who also earned gold in the two-man bob, steered his crew to the gold medal.
After leading by just 0.04sec after Saturday's opening two runs he produced two more consistent runs to clock a combined time of 3min 40.60sec in front of Russian Prime Minister Dmitry Medvedev to finish 0.09sec ahead of second-placed Latvia 1.
"We won and we proved to everybody that we are the best, that is the most important," said Zubkov. "I don't have any emotions right now, honestly. I used them all up in the race."
The USA 1 team, with Vancouver Olympic champion Steve Holcomb in the driver's seat, took bronze, three hundredths of a second ahead of Russian Alexander Kasjanov in the RUS-2 sled. GB 2 came down in 19th position.
