Place five stones, blocks, anything you can use as a marker, every 10 meters (50 meters in total) on a flat surface. You and your friends start at the first marker. On the count of "Ready, set, go!" Run as fast as possible to the second marker, touch the ground, run back to the first marker. Arrive at the first marker, touch the ground and run as fast as possible to the third marker, touch the ground, return to the starting line. Complete one session of this race race following the pattern above until the last marker. The first person who made it back to the first marker and hit the ground, he was the winner. Agree prizes for winners and "punishment" for those who lose early in the game
