The leader must first mark off a circle or square around which the players will run. This can be an obstacle (such as a car or shed) or perhaps just some cones placed on the ground. Players stand in a circle facing the same direction spread out by a least three feet. When the leader says "Go" everyone begins running around the circle (or square). Players must always pass on the outside. Each player tries to pass the person ahead and tag them as they pass. Tagged players are out. When the leader calls "Switch", the players must reverse direction. This turns the tables on the fast runner who is just about to overtake another player. Play until only one player is left.
