The French coach picked Killy for the giant slalom in the 1962 World Championships in Chamonix, France, 50 miles (80 km) away in the shadow of Mont Blanc. But Killy, unaware of his selection, was still attempting to qualify for the downhill event in northeastern Italy at Cortina d'Ampezzo. Only three weeks before the world championships, he skied in his typical reckless style. About two hundred yards (180 m) from the finish, Killy hit a stretch of ice in a compression and went down, rose immediately, then crossed the finish on just one ski—and the fastest time. Unfortunately, his other leg was broken, and he watched the 1962 World Championships on crutches.
Two years later, at age 20, Killy was entered in all three of the men's events at the 1964 Olympics, because his coach wanted to prepare him for 1968. Unfortunately, Killy was plagued by recurrences of amoebic dysentery and hepatitis, ailments that he had contracted in 1962 during a summer of compulsory service with the French Army in Algeria. His form was definitely off, and he fell a few yards after the start of the downhill, lost a binding in the slalom, and finished fifth in the giant slalom, in which he had been the heavy favorite. Yet a few weeks later, he dominated a giant slalom race at Garmisch-Partenkirchen, in Bavaria, counting for the prestigious Arlberg-Kandahar events, the oldest 'Classic' in the sport. A year later, he also triumphed at another major competition, the slalom of the Hahnenkamm races at Kitzbühel that he clinched three times in a row until 1967.
