Berger's gold is the 100th medal for Norway in the history of Winter Olympics.

Hours after the victory, Emil Hegle Svendsen added the 101 medal for Norway when he beat his countryman Ole Einar Bjoerndalen, arguably the greatest biathlete, to win the men's 20-kilometer individual biathlon race.

Svendsen paid tribute to his mentor Bjoerndalen after finishing first in 48 minutes 22.5 seconds.

"I don’t think I would be here if it weren’t for Bjoerndalen. I train with him every day and I try to copy everything he does. I owe him a great deal of thanks. I'm very humble to be on the same team with him," he said.

Bjoerndalen reaffirmed his position as the greatest biathlete in history, becoming the first in the sport to win a medal in the same event at three consecutive Olympics. The 36-year-old veteran tied for the silver with Sergey Novikov of Belarus for his 10th Winter Games medal. Among men, he trails only the great Norwegian cross-country skier Bjorn Daehlie, who won 12.
