Skiing
Freidig and Grane were both skiing clubs. Freidig had the ski jumping hill Lerskallen, which was later taken over by Grane and then Nordstrand. The clubs had several able skiers. The highest ranked competitor at the Holmenkollen ski festival was Herman Huitfeldt, who placed seventh in the Nordic combined in 1895. Walter Aigeltinger finished third in the B class in 1902, and also played on Grane's football team. Th. B. Dürendahl and Wilhelm Wettergren competed successfully in Central Europe in the early 1900s.[3]
Athletics was added to the club's roster in 1921.[2] Rolf Johannson became Norwegian champion in the 1500 metres in 1930, and also took a silver medal in 1929 and bronze medal in 1933. In 1929 he also took a bronze medal in the 800 metres.[4][5] In the throwing events, Halfdan Johnsen took silver medals in shot put with both hands in 1925 and 1926,[6] whereas Joel Arnesen won a bronze medal in the triple jump in 1929.[7]
In orienteering the club won the relay at the National Championship for men in 1947, and for women in 1974.[1]
