Cool Facts
What you wear. Your legs go inside a big sack or pillowcase that comes up to your waist or neck, and you hold it up with your hands while you hop.
How to move. You can't walk or run normally, so you have to bounce and hop forward like a kangaroo to get to the finish line.
The winner. The first person to hop across the finish line wins the race, even if their technique looks pretty silly.
Super fun tradition. Sack races are popular at school field days, summer camps, and birthday parties all around the world because they make everyone laugh and have a great time together.
