A horse trainer takes his horse into the water at Pebble Beach on June 28, 2024 in Bridgetown, Barbados. The swimming horses of Barbados offer a unique and remarkable experience at Pebbles Beach, where racehorses from the nearby Garrison Savannah enjoy their morning swim almost daily between 5:30 am and 7 am. During this ritual, horses swim out surprisingly far to the moored boats before returning to shore, with some staying longer in the water if recovering from injury or soreness after a race. Visitors can observe the horses' individual personalities as they swim and interact with the water, but are advised to respect the guidance of the grooms and maintain a safe distance, as horses can behave unpredictably, especially if frightened.

The Mile O' Mud is a 7/8-mile oval track with a 1/8-mile diagonal lane slashed through the center. The racing lanes are approximately 60 feet wide. On average, the muddy water is four to six feet deep, with three strategically placed holes.
