Sacks races have been going on for as long as there have been sacks. Since bunnies hop, having a good old-fashioned Bunny Hop Sack Race is a great fit for Easter.
Set a start line and a finish line. The contestants stand at the start line inside of their sacks, holding them with both hands at their waist. When the race begins the participants must hop to the finish line while staying inside of their sacks. The first person to cross the finish line wins.
If your party has guests of a variety of ages it is a good idea to run multiple races, one for each age/skill level. The course can be shorter for younger kids and increase in length as the age of participants increase. Be sure to award a prize to the winner of each group and you can crown a grand champion with one last race featuring the winners of each group.
Burlap sacks are an excellent choice to use for your Bunny Hop Sack Race. They are durable so you can keep them to use for your Easter party next year and they are large enough for adults. For young kids burlap sacks might be too large so consider using pillow cases.
