The potato sack race is a competitive game in which participants place both of their legs inside a sack that reaches their waist or neck and jump forward from a starting point toward a finish line. The first person to cross the finish line is the winner of the race. Sack racing is traditionally seen as an activity for children. But people of any age can play in this challenging game. It is also a frequent pastime at fairs, and birthday parties. Sack races are also commonly seen at picnics.
