Slalom made it three from three with a run that suggested stamina is his forte, in the Group Three Prix Noailles at ParisLongchamp.
Nine ran in this 10 ½ furlong race, with plenty of intrigue.
At the off it was Lone Peak who led from Thyme White and Joe Francais.
The pace was generous and Loan Peak moved into a two-length lead under Aurelien Lemaitre.
Thyme White took closer order as they raced towards the final turn, with Lone Peak to the inside and Joe Francais tracking these, followed by Surrey Thunder.
Before the straight, Loan Peak dropped tamely to last.
A wide open race saw five horses in a line and it was Soft Light who went on.
But the two Andre Fabre horses, patiently ridden, moved with menace down the outside.
The giant Syrtis hit the front with a furlong to run, but in behind, Slalom, who had two lengths to make up at that point, began to stay on under Maxime Guyon.
The unbeaten son of Intello ran past Syrtis to record a two length victory, with Surrey Thunder coming home third and Joe Francais fourth.
