Born and raised in St. Anton, Tyrol, Schranz had a lengthy ski career, from 1957 to 1972. He won twenty major downhills, many major giant slalom races and several major slaloms. Late in his career he was the successor to Jean-Claude Killy as the World Cup overall champion; Schranz won the title at age 30 in the third World Cup season of 1969, and repeated in 1970. He was also the downhill champion for those two seasons and was the giant slalom season champion in 1969. Schranz won both the "classic downhills" four times each: the Hahnenkamm at Kitzbühel, Austria, (1966,1969, 1972,1972), and the Lauberhorn at Wengen, Switzerland, (1959, 1963, 1966, 1969). He also excelled at the legendary Arlberg-Kandahar events, winning nine times, from 1957 (Chamonix) to 1970 (Garmisch-Partenkirchen).
