The downhill is an alpine skiing discipline. The rules for the downhill were originally developed by Sir Arnold Lunn for the 1921 British National Ski Championships.
The "downhill" discipline involves the highest speeds and therefore the greatest risks of all the alpine events. Racers on a typical international-level course will exceed speeds of 130 kilometers per hour and some courses, such as the famous Hahnenkahm course in Kitzbuhel, Austria, speeds of up to 150 kilometers per hour in certain sections are expected. Racers must have great strength, stamina, technical expertise and courage if they wish to compete in the downhill.
