She was purchased by trainer Thomas Carter, Jr., a member of the renowned English Racing Colony at Chantilly,[1] in equal partnership with French scientist, Mr. H. Bouy of Senlis, Oise.

Her first loss came at age two against colts in the Grand Criterium at Longchamp Racecourse in Paris when she ran second by a short head to The Condor.

At age three, Plaisanterie's second career loss came against older male horses at Longchamp in the Prix du Prince de Galles when she again was second by a short head.

In Germany on 24 August, she defeated her male counterparts in that country's most prestigious race, the Grosser Preis von Baden, beating The Condor by one and three-quarter lengths.
