VIENNA -- Five-time World Cup race winner Christoph Gruber, who missed the Vancouver Olympics after sustaining a left knee injury in January, has retired.
The 34-year-old Austrian said Wednesday he is leaving the sport to become an airline pilot.
Gruber tore ligaments and bruised a meniscus when he crashed during warmups prior to a downhill race in Wengen, Switzerland.
He was a junior world champion before competing on the World Cup circuit for 12 years.
He won five races, including a super-G on the Olympic course on Whistler Mountain two years ago.
