The British Champions Fillies’ and Mares’ Stakes is a Group 1 race that takes place at Ascot Racecourse in October.

Mares and fillies that are at least three years old can enter, with the race being over one mile and three furlongs, being a part of the British Champions Day. It has been running since 1946, being first called the Princess Royal Stakes.

It has taken place at Newmarket a couple of times since the turn of the 21st century, but it is now back at Ascot. There is a weight handicap system in place, with the prize fund being in the region of £600,000.

It is the last race as part of the fillies and mares division of the British Champions Series. It was in 2013 that the British Champions Fillies’ and Mares’ Stakes was upgraded to a Group 1 race, seeing its prize purse being doubled.
