|}The Oaks Trial Stakes is a Listed flat horse race in Great Britain open to three-year-old fillies. It is run over a distance of 1 mile, 3 furlongs and 133 yards (2553yd) at Lingfield Park in May.
The event serves as a trial for the Epsom Oaks. Prior to World War II, it was called the Oaks Trial Plate.[1] It became the Oaks Trial Stakes after the war.[2]
The left-handed track at Lingfield Park is similar to that at Epsom. It has an undulating, cambered terrain with a sharp downhill turn into the home straight.
The Oaks Trial Stakes was formerly contested over 1 mile and 4 furlongs. It held Group 3 status from 1971 to 1985,[3] and was relegated to Listed level in 1986.[4] It was cut to its present distance in 1990.
Several contenders have subsequently won the Oaks. The most recent was Anapurna, the winner in 2019.
