Ski jumping is a sport in which skiers go down an "inrun" with a
take-off ramp (the jump), attempting to go as far as possible. In
addition to the length that skiers jump, judges give points for style.
The skis used for Ski jumping are wide and long (240 to 270 cm). Ski jumping
is predominantly a winter sport, performed on snow, and is part of the
Winter Olympic Games, but can also be performed in summer on artificial
surfaces (porcelain or frost rail track on the inrun, plastic on the
landing hill). Ski jumping originates from Morgedal, Norway, but the first proper competition was held in Trysil in 1862. The first widely known Ski jumping
competition was the Husebyrennene, held in Oslo from 1879. The annual
event was moved to Holmenkollen from 1892, and Holmenkollen has
remained the pinnacle of Ski jumping venues .
