Torquator Tasso pulled off one of the greatest horse racing shocks by winning the 100th edition of the Prix de l'Arc de Triomphe at Longchamp on Sunday.
The German underdog stormed up the outside for a stunning victory in Europe's richest race at odds of 80-1.
Torquator Tasso handled the heavy ground brilliantly under Rene Piechulek, giving trainer Marcel Weiss a sensational success with his first Arc runner to land prize money of €2.9million (£2.5m).
Tarnawa was second ahead of 3-1 favourite Hurricane Lane, with Adayar finishing fourth.
The four-year-old Torquator Tasso became the third German winner of one of the most prestigious races in the world after Star Appeal (1975) and Danedream (2011).
"That was beautiful. He's a very nice horse, he's all heart," said an elated Weiss.
Weiss added: "He's a very strong horse and Rene is a very cool jockey."
Torquator Tasso was bought for only €24,000 in what must go down as one of the most shrewd racing investments in history.
