What is the role of the Stewards during a race according to regulations?

The role of the Stewards during a race is primarily to ensure compliance with medical regulations, which includes monitoring the health and well-being of the horses, inspecting them for any signs of illness or disqualification due to medical reasons, and ensuring that all horses are fit to compete. This responsibility is crucial to maintaining the integrity of the race and the safety of both the horses and the jockeys.

The Stewards are responsible for enforcing rules related to medication use and ensuring that no prohibited substances are present in the horses' systems prior to the competition. Their oversight helps to uphold fair competition and the welfare of the animals involved in racing.

While the other options touch upon various aspects of race management, they do not accurately represent the central function of the Stewards during racing events. Their focus is not on betting operations, event logistics, or horse grooming, which are managed by other personnel within the racing organization. Instead, their role is specifically aligned with upholding the health standards and regulatory compliance necessary for a fair and safe racing environment.
