Why are Racing Horses all Thoroughbreds?

For amateurs learning about horse racing, you might wonder why Jockeys are always racing the breed of Thoroughbreds! Thoroughbreds are the world's fastest and most prized horse breed. These athletic horses are known to carry heavier loads and run longer distances without getting tired. They have a strong work ethic and are naturally athletic.

Thoroughbreds can race up to 39 miles per hour on a one-mile track.

Imagine: if you were a jockey, what would be going through your head? Trust me, the movie "Stripes" is as close to fiction as it gets. Especially since Zebras can only run an excess of 30 miles per hour. Would you want to win the race by getting the fastest horse possible or would you want to ride the average horse? Of course you would want to race the fastest horse you can find, and this is why Thoroughbreds are the horses that everybody races.
