What is Run-A-Munk?

This year is Woldumar's 7th annual Run-a-Munk trail walk/run. We offer the opprotunity for members of the community to run through Woldumar's beautiful trails for a small entry fee, and all proceeds from the event go towards furthering our mission to educate people about the environment. This event is designed to promote healthy lifestyles and community engagement.

If you would like to become a sponsor or volunteer for this event, contact race director David Stierley at 517-927-8955.
