A beaming Queen Elizabeth II received the Gold Cup trophy on Thursday after becoming the first reigning British monarch in history with a winning horse in Royal Ascot’s biggest race.
The 87-year-old queen watched joyously as, Estimate, her much-fancied young filly crossed the finish line.
The queen, who has been on the throne for 61 years, has attended Ascot every year since 1945. Thursday’s win was her 22nd overall at Ascot, but the first in the signature Gold Cup.
The Queen joins with her horse, Estimate, in the Winners Enclosure, a first for a reigning monarch in the race’s 207-year history.
The horse-loving queen is widely respected as an expert on horse breeding and racing.
According to the BBC, the queen has won various races at Ascot at least 21 times, the first, famously, came just two weeks after her 1953 Coronation when her horse, Choir Boy, won the Hunt Cup.

Beautiful horse! I don’t think I’ve ever seen her smile this much, she looks so proud and happy.
Very nice to see the queen so happy. Congratulations on a terrific win. Beautiful horse and jockey did an amazing job racing the horse.
