Regret S.

A nine furlong (1 1/8 mile) turf race for 3-year-old fillies, the Regret Stakes is held at Churchill Downs. Named after the filly Regret, who won the 1915 Kentucky Derby, the Regret Stakes has been run at multiple distances but has stuck to its current distance since 2003. Since then, horses such as Pure Clan, Keertana and Centre Court have won the race.
