In which sport did Georg Hackl often named as the 'Speeding Weißwurst' become famous?

Georg Hackl (often named: Hackl Schorsch, born 9 September 1966) is a German former luger who was three time Olympic and World Champion. He is known affectionately as Hackl-Schorsch or as the 'Speeding Weißwurst' (traditional Bavarian sausage) a reference to what he looks like in his white bodysuit coming down the luge at fast speeds.

Hackl was born in Berchtesgaden, Bavaria. He took up luge as part of his physical education lessons whilst at school, learning to slide at the Königssee track.

He won his first Winter Olympic Games luge medal in 1988 in Calgary, when he finished second in the singles event, while placing fourth in the doubles. Four years later, he improved his performance to win the gold, a feat he repeated in 1994 and 1998. In 1998, he won the gold by clocking the fastest time in all four runs, the first in Olympic history in the men's singles to do so. That year he was named as German Sportsman of the Year. Hackl won the silver medal again in the 2002 Games, becoming the first Winter Olympian to win a medal in five consecutive Winter Olympics. Most recently, he placed 7th in the 2006 Winter Olympics.

Hackl has retired from active participation and got involved in coaching after the 2006 Winter Olympics. He is responsible for a group of German lugers nicknamed the "Sunshine Training Group".
