American Thoroughbred Racing is a popular equestrian sport that involves racing horses bred for speed and stamina. The races typically take place on dirt or turf tracks, with distances ranging from five furlongs to two miles. The most prestigious events include the Kentucky Derby, Preakness Stakes, and Belmont Stakes, which together form the Triple Crown. Thoroughbred horses are registered with the Jockey Club, which maintains their lineage and racing records. Races are often organized by various organizations, including the National Thoroughbred Racing Association (NTRA). Betting on races is a significant aspect of the sport, attracting fans and generating revenue for tracks and owners.
