Queen Elizabeth Adds Horse Title to Crown Queen Elizabeth is about to be a great-grandmother and celebrate the 60th anniversary of her coronation. But she now has another title to add her repertoire: the first member of the Royal Family to win Britain's prestigious Gold Cup race. Queen Elizabeth's 4-year-old horse Estimate won the two and a half mile race today, which is part of the five-day Royal Ascot race that ends on June 20. Her son, Prince Andrew Duke of York presented an ecstatic Queen with the Gold Cup as a reward. According to the Royal Ascot website, Gold Cup Day is known as "ladies day" because it is when the female attendees roll out their greatest outfits. Although the race began 207 years ago, a horse of the royal family had yet to win the Gold Cup title, giving Queen Elizabeth's victory a place in filial history. Estimate has won other races as well, most recently the Sagaro Stakes in May, which also took place at Ascot, according to the BBC.
