The first ski jump used by IF Birkebeineren was called Langstrandsbakken and existed since 1902 to 1935, allowing jumpers to jump up to almost 40 metres.
In 1935, the club's new ski jump was opened in Krokstadelva's Bjørkedokken. Bjørkedokkbakken K69 even hosted the 1960 Norwegian Nordic Combined Championships, won by Tormod Knutsen. However, later the hill lost its prestige and at least since 1980s the place has been abandoned.
