In the final season before the launch of the World Cup, Sun Valley hosted the world's top racers in 1966 at the "American International" in late March, with a full slate of races for both men and women. With the 1966 World Championships not run until August, it was one of the biggest alpine racing events since the 1964 Olympics. The Austrians swept the men's downhill (Heini Messner, Karl Schranz, and Egon Zimmermann), while Jean-Claude Killy of France won the slalom, with Schranz as runner-up. The two switched places in the one-run giant slalom. Erika Schinegger of Austria, Nancy Greene of Canada, and Marielle Goitschel of France were the top three in the women's downhill, while Goitschel and teammate Annie Famose finished 1–2 in the slalom. Goitschel, Greene, and Famose were the top finishers in the giant slalom and France took the overall team title.
