The "Triple Crown" refers to a prestigious achievement in horse racing, specifically for three-year-old thoroughbreds. It consists of winning three significant races: the Kentucky Derby, the Preakness Stakes, and the Belmont Stakes. These races are held annually in the United States and are known for their rich history and competitive fields. Winning the Triple Crown is a rare feat, with only 13 horses achieving it since its inception in 1919. The last horse to win the Triple Crown was Justify in 2018. This accomplishment is celebrated in the racing community and symbolizes excellence in the sport.
