What is a requirement for the number cloth worn by each horse?

The requirement for the number cloth worn by each horse is that it must correspond with the horse's official program number. This identification is crucial for several reasons: it helps race officials, spectators, and betting individuals easily identify each horse during races. The seamless correlation between the number cloth and the program number enhances organization and clarity throughout the race event.

Having the number cloth match the official program number ensures that there is no confusion about which horse is which, especially in situations where multiple horses might have similar colors or markings. This systematization also plays an essential role in maintaining the integrity of the race and ensuring that betting outcomes are appropriately separated and administered based on the correct horses.
