Germany's Felix Loch successfully defended his gold medal in men's luge on Sunday at the Sanki Sliding Center in Sochi.
Already owning gold from competition in Vancouver in 2010, Loch posted a combined four-run time of 3:27.526. That included a track-record third run of 51.613.
"I'm really overwhelmed. We have worked very very hard over the summer," Loch said. "[Coach] Georg Hackl and I are a superb team. He helps me a lot."
"We experimented a lot over the summer and it paid off."
Russia's Albert Demchenko was unable to catch the defending Olympic champion, but snagged a silver medal with a time of 3:28.002.
Italy's Armin Zoeggeler became the most decorated men's luge athlete of all time with a bronze medal-winning time of 3:28.797 for his sixth medal in as many Olympic appearances.
Zoeggeler eclipsed Loch's coach, Hackl, for the all-time mark with two gold, one silver, and three bronze over the Italian's career.
Canada's top slider was Calgary's Sam Edney, who finished in 11th with a combined time of 3:29.777.
Edney will return to the luge track as part of the Canadian team relay squad, with competition beginning in that event on Thursday.
Olympic rookies Mitchel Malyk and John Fennell, both 18-year-olds from Calgary, finished 26th and 27th overall, respectively.
"I can't complain, it's my first Olympics, it's a new experience," Fennell said. "The amount of people that showed up for the race was unthinkable.
