The Road to the Kentucky Oaks is a points system to qualify for the Kentucky Oaks, one of the most important races for three-year-old fillies and held the day before the Kentucky Derby at Churchill Downs. It features roughly 30 stakes races for Thoroughbred fillies between September (when the horses are age two) and April (when they are three) – the number and specific races have varied slightly over the years. The point system replaces the previous qualifying system which was based on graded stakes earnings.
