Simen Hegstad Krueger got a surprise gold medal on Sunday and Norway claimed the first-ever Olympic skiathlon podium sweep after dominating the men's cross-country event at the Pyeongchang Games.

Olympic debutant Krueger took the lead around the 24-km mark of the 30-km race that mixes the freestyle and classic skiing techniques and held on to claim a shock win that had him looking over his shoulders in astonishment at the finish line.

"When I got those meters I had to go for it," Krueger said. "I did not believe it when I turned and there was no one there, (I thought), 'What is happening?' and 'Do not look back.' I just had to keep pushing forward until the final."
