A piste (/ p iː s t /) [1] is a marked ski run or path down a mountain for snow skiing, snowboarding, or other mountain sports. This European term is French [2] ("trail", "track") and synonymous with 'trail', 'slope', or 'run' in North America. The word is pronounced using a long "e" sound so that it rhymes with "beast".
Past the landing slope is the outrun, which is either flat or even uphill, where the skier can slow down. [1] The speed of the skier is normally measured about 10 meters (33 ft) before the end of the takeoff; jumpers can reach speeds of 95 kilometers per hour (59 mph) on large hills and 105 kilometers per hour (65 mph) on ski flying hills.

Ski geometry is the shape of the ski. Described in the direction of travel, the front of the ski, typically pointed or rounded, is the tip, the middle is the waist and the rear is the tail. Skis have four aspects that define their basic performance: length, width, sidecut and camber. Skis also differ in more minor ways to address certain niche ...
Slope angle (Φ) is the angle measured from the horizontal to the plane of a slope with a clinometer. Aspect of slope (AS) is the compass direction towards which a slope faces, normal to the contours of elevation, given either degrees from true North N = 0° = 360° or as N, NE, E, SE, S, SW, W, NW.
A 100% slope is a 45-degree angle. In general, beginner slopes (green circle) are between 6% and 25%. Intermediate slopes (blue square) are between 25% and 40%. Difficult slopes (black diamond) are 40% and up. Although slope gradient is the primary consideration in assigning a trail difficulty rating, other factors come into play.
The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt".
Two ski tracks with different degrees of sinuosity on the same slope Sinuosity , sinuosity index , or sinuosity coefficient of a continuously differentiable curve having at least one inflection point is the ratio of the curvilinear length (along the curve) and the Euclidean distance ( straight line ) between the end points of the curve.
2018. 2022. 2026. Medalists. Ski jumping has been included in the program of every Winter Olympic Games. From 1924 through to 1956, the competition involved jumping from one hill whose length varied from each edition of the games to the next. Most historians have placed this length at 70 meters and have classified this as the large hill.
