Step into a large sack, usually a burlap or cloth bag, and pull it up so the top edge sits at your waist. Grip the top edges of the sack firmly with both hands to keep it from slipping down as you move. Line up at the starting mark alongside the other racers, ready to jump forward on the starting signal. Hop forward with both feet together inside the sack, since walking or taking normal steps is not allowed and usually disqualifies you. Keep your balance by leaning slightly forward and using small, controlled jumps rather than big leaps, which are more likely to make you fall. If you tumble over, get back up quickly, still inside the sack, and continue hopping toward the finish line. The first racer to cross the finish line while still inside their sack wins.
