Ski flying in the context of "Nordic skiing"

Rødkleiva is a hill located in Nordmarka in Oslo, Norway. It was taken into use as a slalom hill in 1947 and was used for the combined event of the Holmenkollen Ski Festival eleven times between 1947 and 1963. It hosted the slalom events for the 1952 Winter Olympics, which saw a crowd of at least 25,000 spectators. The Olympic course was 422.5 meters (1,386 ft) long and had a drop of 169 meters (554 ft). The course gradually fell into disrepair and was closed in 1988.

The hill has several times been launched as a potential location for a ski jumping hill. The first idea came in 1912; later options to replace Holmenkollbakken resurfaced during the 1930s and the 1970s, but were quickly rejected. With the closing of Midtstubakken, Oslo's normal hill, in the late 1980s, Rødkleiva was again launched as a jumping hill. Vikersundbakken—Northern Europe's only ski flying hill—was in the late 1990s proposed replaced by a new hill in Rødkleiva. The plans received support from the Norwegian Ski Federation, but the municipality and state were not interested in issuing grants and the proposal was finally laid to rest in 2006.

A ski jumping hill is a sports venue used for ski jumping. They vary in size from temporary handmade snow structures to permanent competition venues. At the top is an in-run where the jumper runs down to generate sufficient speed, before reaching the jump. The skier is then airborne until landing on the landing slope. The last part of the hill is the out-run, which may be either flat or even uphill, allowing the jumper to stop. The construction point (K point) is used to determine the distance points for a particular length. The size of a hill is measured in the hill size. Hills with a hill size exceeding HS185 are designated ski flying hills; there are five such hills in the world.
