Hurricane Run gave Kieren Fallon his first Prix de l'Arc de Triomphe with a scintillating success at Longchamp. The Irish Derby winner, providing French trainer Andre Fabre with his sixth Arc victory, got a dream passage on the rails to lead a furlong out.
The champion French stayer Westerner was second, with last year's winner Bago third. Fallon let Hurricane Run bide his time at the back of the field and allowed several rivals to get first run in the rain.
Frankie Dettori was the first to commit on Cherry Mix. But Godolphin's hope could not maintain his challenge, while Shawanda flattered briefly before Vodafone Derby winner Motivator kicked for home from Westerner.
However, Fallon was gathering Hurricane Run for his effort and made his move by bursting through the gap on the rail to quickly settle the issue. The rider was completing a Group One treble following his earlier wins on Rumplestiltskin in the Prix Marcel Boussac and the Prix Jean-Luc Lagardere on Horatio Nelson.
He told BBC Sport: "It's the shortest way around (on the inside). He got shuffled back at the start - I didn't really want to be that far back, and it got very rough turning for home. But I was lucky enough to have a horse to get me out of trouble.
"He travelled so well, and I don't think I have ever ridden a horse with that turn of foot. I was on a horse that travelled and was good enough to go and quicken and go on and win."
Fabre, whose past Arc winners were Sagamix (1998), Peintre Celebre (1997), Carnegie (1994), Subotica (1992) and Trempolino (1987), said: “You can't compare winners, because every horse is different. He is special - he is an Arc winner.”
Owner Michael Tabor added: "He's come from an impossible position and has a turn of foot second to none. It's just incredible - like father (sire and 1999 Arc winner Montjeu) like son."
Connections added the colt may go for the Breeders' Cup and will definitely stay in training as a four-year-old.
