Which Australian racehorse retired unbeaten after winning all 25 of her races?

Black Caviar retired unbeaten after winning all 25 of her races, making her one of the most celebrated sprinters in horse-racing history.

The Australian mare raced from 2009 to 2013 and won major sprint races in Australia and England. Her victories included four editions of the Lightning Stakes at Flemington and the 2012 Diamond Jubilee Stakes at Royal Ascot, her only race outside Australia. She was trained by Peter Moody and ridden in most of her races by jockey Luke Nolen.

Black Caviar’s record is sometimes confused with Winx’s, because both mares became Australian racing icons in the same era. Winx won 33 consecutive races, while Black Caviar’s defining statistic was her perfect 25-race record. Black Caviar was inducted into the Australian Racing Hall of Fame in 2017, and her undefeated career helped make her a global symbol of sprinting excellence.
