The purpose of the jockey in horse racing is to guide and control the horse during a race. Jockeys play a crucial role in maximizing their horse's performance, employing various strategies to position themselves effectively on the track. They must also be adept at interpreting the horse's behavior and stamina, as these factors can influence race outcomes. Jockeys require extensive training and skill to navigate races, and their success depends significantly on their ability to work in harmony with the horse.
