Margarula had only previously won in handicap company and had finished fourth in a group two event in her last race. Trained by Jim Bolger, the filly was bred in Ireland by Airlie Stud.
Mrs. J. S. Bolger's Margarula, an Irish-bred daughter of Douyon sent off at 33-1 odds, produced strong late run to defeat odds-on favorite Quarter Moon in Sunday's Irish Oaks (Ire-I) at The Curragh. Ridden by Kevin Manning, Margarula was settled in the rear for much of the 1 1/2-mile race for 3-year-old fillies, and kicked in gear in the final furlong to win a length over Quarter Moon, the 4-5 favorite trained by the red-hot Aidan O'Brien. Lady's Secret, a 16-1 chance trained in England by Barry Hills, was six lengths further back in third.
