What is a "racehorse"?

A racehorse is a horse bred and trained specifically for racing. These horses are known for their speed, agility, and endurance, and are often finely tuned and carefully trained to achieve peak performance. Thoroughbred horses are one of the most common breeds used for racing, but other breeds such as Arabians, Standardbreds, and Quarter horses are also used in racing. These horses are often trained by experienced trainers and ridden by skilled jockeys, and races can range from short sprints to longer distances such as the Kentucky Derby or the Belmont Stakes. The sport of horse racing has a rich history and is enjoyed by many around the world, with races taking place at tracks and courses on every continent.
