About

Some charities have run rubber duck races in which hundreds or thousands of rubber ducks are dumped into a river, pool, or other body of water and then floated down a race course marked off with buoys. The first one to float past the finish line is the winner (similar to the game Poohsticks). The rubber ducks are then retrieved and used again later. Due to environmental concerns, sites for duck races must be chosen with care. There are hundreds of races held in the USA and internationally. The largest race in the United States benefits the Freestore Foodbank in Cincinnati, Ohio; over 100,000 ducks are raced to raise money for the organization.
