Here is a fun relay game for two or more teams.

You will need a big choccy Easter Egg or a decorated, hard boiled egg and a spoon for each team.
Set out a course suitable for the size and age of your contestants.
The front runner in each team places the egg on the spoon and, when the starter says, "Go!", runs the length of the course and back keeping the egg on the spoon without holding on to it.
The egg and spoon are passed to the next relay member.
If the egg is dropped the team dropping it has to start all over.
The winning team is the quickest to have all members complete the course.
