The Oaks is the fillies' Classic run over a mile and a half at Epsom Downs, the day before the Derby. A Group 1 contest for three-year-old fillies, it shares the Derby's demanding, undulating course. The 2027 running is expected in early June.
Thundering On won the 2026 Oaks for Joseph O'Brien, ridden by Dylan Browne McMonagle, surging clear on Ladies Day. As the fillies' middle-distance championship, it is one of the highlights of the Epsom Derby Festival and a major betting race.

The Oaks is the fillies' middle-distance Classic and a major betting race. Win and each-way markets centre on the leading fillies from the Guineas and the spring trials, with Ballydoyle and the Gosdens regular forces. Stamina for the mile and a half is the key question.
Ante-post markets run from the spring trials, rewarding those who can read which fillies will stay the trip on Epsom's demanding track. Non-runner-no-bet offers nearer the race remove the ante-post risk.
Epsom's unique course finds out any filly not truly staying or balanced. Bet each-way on a sensible budget and remember that, as at the Derby, even short-priced favourites can come unstuck on the camber and gradients.
The 2027 Oaks is expected in early June at Epsom Downs, the day before the Derby. The exact date will be confirmed and this page updated.
Thundering On won the 2026 Oaks for Joseph O'Brien, ridden by Dylan Browne McMonagle.
It is run over one mile four furlongs at Epsom, the same demanding course as the Derby.
Epsom's undulating, cambered track with its downhill run to Tattenham Corner demands stamina and balance, making it a true championship test for fillies.
Enable won the 2017 Oaks before becoming a dual Prix de l'Arc de Triomphe winner and one of the great modern fillies.
