Have the group divide into pairs. Each pair will need a sack or pillowcase. Determine a starting line and a turn back line. Each pair must keep at least one foot inside the sack or pillowcase at all times during the race. Otherwise they will be disqualified. Each team must figure out the best method to keep the sack or pillowcase on and move quickly. The object is to run as a team to the turn back line and back first. It may help to tie the sacks etc. around people's legs or you may make the untied sack or whatever part of the game.
