Prix Jean Prat
Bireme did run as a two-year-old, when she won a thirty-runner maiden race over seven furlongs at Newmarket Racecourse in October. She was then matched against colts in the Houghton Stakes over the same course and distance later that month and finished third behind Night Alert and Posse. The first and second both developed into top class milers in 1980: Night Alert won the Prix Jean Prat while Posse won the St James's Palace Stakes and the Sussex Stakes.
