Mill Ridge had the great pleasure of raising Harmonious for her owners and breeders Pam, Emily, and Martin Wygod. Sent to John Shirreffs in California, Harmonious dominated the 2010 three-year-old filly turf division, rolling to victories in its most prestigious races: the American Oaks (G1) and Queen Elizabeth II (QE II) Challenge Cup (G1). Her victory in the QE II was visually one of the most impressive: utilizing a tremendous turn of foot she was able to lengthen her stride through the stretch to win by a widening 4 ½ lengths.
