Ascot Racecourse is a dual-purpose British racecourse, located in Ascot, Berkshire, England, which is used for thoroughbred horse racing. It hosts 13 of Britain's 36 annual Flat Group 1 horse races and three Grade 1 Jumps races. The Royal Meeting held each June, remains a major draw, its highlight being The Gold Cup. The most prestigious race is the King George VI and Queen Elizabeth Stakes run over the course in July. Until 1939, Royal Ascot was the only race meeting held at the racecourse. The Gold Cup remains the feature race of the third day of Royal Ascot, traditionally the busiest day of the week, when high fashion and exquisite millinery take centre stage alongside flat racing's most elite stayers.
Each of the five days of Royal Ascot begins with the Royal Procession at 2pm, when the Queen and other members of the royal family arrive down the straight mile in the Royal Landaus, accompanied by the playing of the National Anthem and the raising of the Royal Standard. Royal Ascot is Britain's most valuable race meeting, attracting many of the world's finest racehorses to compete for millions of pounds in prize money (just over £7.3million in 2019). Approximately 500 horses race across the five days.
