Horse racing is a sport related to the equestrian world. It usually consists of a horse racing jockey in a place specially prepared for this purpose, called racetrack. This sport has existed throughout history and today is closely related to betting and gambling.
The history of horse racing has its origins in prehistory, among the nomadic tribes of Central Asia who domesticated horses about 4,500 years before Christ. Horse racing has been an organized sport that has evolved in all major civilizations from Central Asia to the Mediterranean. These races, popular today were once were held in the first Olympics in Greece. The Romans later adopted the activity. The more modern races have their origin in the twelfth century, when English knights returned from the Crusades with Arab horses. It is estimated that became truly professional sports around the year 1700.
Attendees can go to the racetrack to watch the races and place bets, which happen in an entertaining way about every thirty minutes. Horse riding and racing involves many other activities such as horse racing preparation (through practice by the riders and horses), as well as specialized veterinarians in the field, blacksmiths and all the staff needed to run the show.
There are also businesses and equestrian-related activities that move a lot of money, such as horse breeding and training. Such businesses generate constant economic activity as it is possible to find horses bred and sold for thousands and millions of dollars.
