Sired by Sharpen Up, he was out of the mare Trephine who was a daughter of Canadian Horse of the Year, Viceregal, a first-crop son of Northern Dancer.

A few days before the Arc, Laura de Seroux, on behalf of Los Angeles businessman Bruce McNall, purchased a half interest in Trempolino.

[1] The eleven-horse field for that year's Arc was a strong one with top European runners such as Tony Bin, Triptych and Reference Point, the latter sent off as the betting favorite.

Pat Eddery was aboard Trempolino again six weeks later in the Breeders' Cup Turf at Hollywood Park Racetrack in California in which he finished second to Theatrical.

Retired to stud, Trempolino stood at Gainesway Farm in Lexington, Kentucky where he remained until 2000 when he was sent to Paul de Moussac's Haras du Mezeray in France.
