[.Any Ideas?]

I'm probably making a bigger deal about this then I should, but I want to ask for some opinions.  In one of my classes for school it is a requirement to do a 10 hour service project that promotes fitness.

 Here is kinda my idea:

Have a 5k (3 mile) walk for elementary aged kids (it can be shorter if needed), not sure if during school or after school, or on a weekend or what (this is why I need help/ideas!)  I would make flyer type invitations to give out.  After the walk I would show the kids ways to promote  healthy lifestyles and have healthy snacks afterwards.

K give me some ideas (and with your names if it's anonymous:)!!

Anything helps!

Thank you in advance!
