Modern horse racing has evolved into an exclusive, glamorous event. Attendees at premier events like the Kentucky Derby and Royal Ascot wear trendy clothing and hats which must adhere to stringent rules in order to be worn at events such as these. Horse racing also serves as a popular gambling activity with many people betting on its outcome during each race.

At horse races, each runner is given a number that corresponds with its position on the field. Stewards are responsible for overseeing each race and making sure participants follow all relevant regulations; additionally, disciplinary procedures will be enforced against those who violate game rules.

Prior to each race, the initial step in the weighing-in process for horses takes place, where their condition is evaluated and their weight determined. Once these horses have been saddled and paraded past an official for inspection, stewards can begin overseeing the event itself.

Injury to horses requires immediate removal from a race. If they cannot run the remaining distance of their race, disqualification occurs and win bets forfeited. A horse who has never won before may qualify for maiden special weight races which allow it to carry three to five fewer pounds than male horses competing in that particular event.

Claiming races offer runners an equal chance at competing against similar horses on equal terms, allowing each runner to carry different amounts of weight based on age, sex and racing experience. Claiming provides owners with a risk-reward situation; winning can offset potential loss against more experienced horses.
