Racing at age two in France for his British breeder/owner,
Jefferson Davis Cohn, Sir Gallahad earned victory in three of his five starts but was overshadowed by the 1922 Champion colt,
Epinard. At age three, he won four races, most notably the
French 2,000 Guineas (Poule d'Essai des Poulains). At four, he won three important races in France and in
England won the
Lincolnshire Handicap. That year, he also went head-to-head with Epinard, winning a 6½ furlong event. ==Stud career==
