Vikersundbakken or Vikersund Hill is a ski flying hill at Vikersund in Modum, Norway. It is one of the two largest purpose-built ski-flying hills in the world. Nine world records have been set there, including the current record of 253.5 meters, set by Stefan Kraft. The complex consists of a large hill, a normal hill, and several training hills.
Ski flying is a winter sport discipline derived from ski jumping, in which much greater distances can be achieved. It is a form of competitive individual Nordic skiing where athletes descend at high speed along a specially designed takeoff ramp using skis only; jump from the end of it with as much power as they can generate; then glide – or ‘fly’ – as far as possible down a steeply sloped hill; and ultimately land within a target zone in a stable manner.
The hill originally constructed by Kristian Hovde was opened in 1936 as a large hill. It was rebuilt as a ski flying hill in 1964 and was modified in 1989, 1999, and 2010. The present large hill was built in 1988. Vikersundbakken was the first ski-flying hill to receive floodlights in 2006. It hosted the FIS Ski Flying World Championships in 1977, 1990, 2000, and 2012 and will do so again in 2022.
The hill was rebuilt for the 2012 Ski Flying World Championships. It was the first in the world with a hill size of 225 meters, making Vikersundbakken the largest ski-flying hill in the world. Up to 20,000 spectators can watch the action. It has been built further into the terrain with sidewalls made of natural gravel to avoid wind problems during competitions. Furthermore, it has been slanted slightly to the south from the inrun area to further reduce wind problems.
