Bred at haras de Martinvast by Baron Arthur de Schickler, he was a half brother to the Prix Royal Oak winner Escarboucle (b c 1882 Doncaster). His grandsire, the Derby winner Thormanby (ch c 1857 Melbourne or Windhound), was most likely a full brother to his 3rd dam, Lady Hawthorn (b f 1853 Windhound).

Lightly raced as a two and three year old, he won one race each year, the Grand Prix de Dieppe and the Prix Daru respectively. In 1888 he won six, including the Prix d'Apremont at Chantilly and the Prix de Bois-Roussel at Fontainebleau. That year he also travelled to England where he finished third in the Lancashire Plate at Manchester. In 1889 he won ten, including the Prix d'Apremont for the second time, the Prix d'Ispahan, the Grand Prix de Deauville and the Prix d'Octobre. In 1890 he won nine, including the Prix de Deaville, the Grand Prix du Sart and the Grand Prix de Deauville for a second time. Over the course of 1889 and 1890 he won nineteen consecutive races. In all he won twenty-seven races from forty-three starts, being placed nine times, and earning 363,337.50 francs.

He retired to stud at haras de Martinvast perfectly sound and healthy. His stud fee, at 500 guineas, was equal to that of St Simon (br c 1881 Galopin) in England. His best sons were Le Sagittaire (ch c 1892), winner of the Grand Criterium, Prix Ganay, Prix Greffulhe, Prix Lupin and Prix Morny, and Le Samaritain (gr c 1895), winner of the Grand Prix de Deauville and the Prix Daru. The latter sired Roi Herode (gr c 1904), who in turn sired The Tetrarch (gr c 1911). Le Sancy also got two Prix du Jockey Club winners, Ex Voto (b c 1900) and Palmiste (gr c 1894), two Poule d'Essai des Pouliches winners, Xylene (b f 1901) and Semendria (gr f 1897), the latter the winner of the Prix de Diane as well, and one Prix Royal Oak winner, Chambertin (gr c 1894). His daughter, Toison d'Or (gr f 1901) was the dam of Alcantara (b c 1908 Perth), winner of the Prix du Jockey Club, Prix la Rochette and Prix Lupin, and a very good stallion. Le Sancy died in 1901.
