After the World Cup events in Antholz-Anterselva in late January, Thingnes Bø was a close second to Fourcade in the overall World Cup. Having dominated the preceding World Cup events, expectations were high for Thingnes Bø in the upcoming Winter Olympics in Pyeongchang, South Korea. However, Thingnes Bø had a disappointing start to the games with a season-worst 31st-place finish in the sprint race. The following pursuit race ended little better for Thingnes Bø, who finished 21st with six missed shots. In the individual 20km race, which is usually considered his weakest race discipline, Thingnes Bø finally managed to find his best level. Despite two misses, he won the competition with a small time gap to Slovenian Jakov Fak and Austrian Dominik Landertinger in third place. Rival Fourcade finished fifth with equal shooting, but trailed Thingnes Bø by a substantial amount of time. Thingnes Bø finished the Winter Olympics with a disappointing 16th-place finish in the mass start race, but managed to take two additional silver medals in the mixed relay and men's relay.
