A potato race is one of several similar racing events where contestants compete to collect a number of potatoes as quickly as possible. Participants may run on foot or be mounted on horseback, depending on the style of race. It is not clear precisely when or where the potato race originated. Potato races of both types were most popular in Australia, England, Scotland, the United States of America and Wales. Potato races were commonly held at community events such as county fairs, rodeos, picnics, and track and field meets from at least the middle of the 19th century until approximately the 1930s.
