Jørgen Graabak chased down the leading pack to take home a brilliant gold medal for Norway in the men's individual large hill/10km Nordic combined in a time of 27:13.3.
There was a tense race between four skiers down the finishing straight, with Graabak just pipping teammate Jens Lurås Oftebro on the line by 0.4 seconds.
Oftebro's silver made it a Norwegian one-two, with Japan's Akito Watabe taking home bronze.
"It's what dreams are made of. It's unreal to be honest, I can't quite believe it," said Graabak. "I have to see the replay first. It's hard to believe, but of course, I'm really happy."
"It demanded everything I've got, so I'm really, really tired at the moment. It was a really tough race, starting over two minutes behind. I didn't think it was possible. It's unreal, I don't know what to say."
German Manuel Faisst was the unfortunate skier to come in fourth after a grueling battle.
Earlier in the race, Norway's Jarl Magnus Riiber had perhaps one of the Winter Olympics' biggest nightmares.
Leading by more than 40 seconds after his performance in the ski jump portion of the event, Riiber took a wrong turn and headed down the home straight prematurely — instead, he should have taken the other turn to begin his second lap.
Riiber had to turn around and ski the wrong way up the finishing straight to go back and begin his second lap, which cost him the entire lead he'd built up. He eventually finished eighth.
Riiber was only allowed out of isolation yesterday after a positive Covid test and perhaps hadn't had the time to scope out the course.
