- Horse racing is one of the most ancient competitive sports in the world. Historians believe that it originated from 4500 BCE, when horses were first domesticated by nomadic Central Asian tribes. Sports are generally known to evolve throughout time, but not horse racing. Despite its thousand-years-long history, its core concept never changed: the horse that reaches the finish line first wins the race. It remains to be a popular game of speed, stamina, and strategy.
