THE ROOTED HALF MARATHON & 5K
About this race
Lace up your running shoes and join us for an inaugural and unforgettable autumn adventure through the scenic trails of Orion Oaks County Park! The Rooted Half Marathon & 5k offers an experience for every skill level, from seasoned trail runners to first-time 5k participants to someone out for a supported hike. Enjoy the stunning fall backdrop as you are immersed in the natural surroundings so lush you would think you are in a northern Michigan forest and not an urban area! The course features well-maintained, multi-use trails that wind through wooded and grassy areas, offering a mix of flat to gently rolling terrain suitable for all abilities.
Whether you're pushing for a personal best or enjoying a leisurely hike, you'll find the perfect challenge. And you don't have to go it alone—5K runners can sign up for the Doggie Division and bring your leashed dog to share in the fun!
After you cross the finish line, celebrate your accomplishment with a truly great finisher award that will serve as a memento of your epic fall run.
