On her final appearance of the season, Polygamy was sent to France to contest the Group One Criterium des Pouliches over 1600 metres at Longchamp Racecourse on October 7. Ridden by Eddery she started at odds of 8/1, making her the best-fancied of the four British runners.
Polygamy began her second season in the Group Three 1000 Guineas Trial over seven furlong at Ascot in April.
