Coming into the &lt;a href="2015%E2%80%9316%20Biathlon%20World%20Cup"&gt;2015/16 season&lt;/a&gt;, Thingnes Bø was again considered a potential challenger to the stranglehold rival Martin Fourcade held on the World Cup. However, a disappointing start to the season ruined Thingnes Bø's aspirations in the overall World Cup, and he subsequently changed his focus to the 2016 Biathlon World Championships at home grounds in Holmenkollen, Oslo. The first success came when Thingnes Bø won the World Cup sprint race in Ruhpolding ahead of fellow countrymen Emil Hegle Svendsen and his older brother, Tarjei Bø. In the World Championships in March 2016, Thingnes Bø won the Mass Start race when he outsprinted Martin Fourcade and Ole Einar Bjørndalen on the final lap.
