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.
Have more fun and share the experience with family and friends! During registration you will be given the opportunity to join or create a PACK which is a social group. PACKS can span across any race distance, onsite or virtual.

Please note: This is a dog park with dog pens. The race start and finish area will be inside one of the dog pens that opens onto the park trail system. Dogs MUST be leashed at all times while in the event staging area. There will be a couple of pens at the park which will be open to off leash dogs. Dogs must also stay on leash while on the trails. The only place during the event where your dog can be off leash are the OPEN dog pens. For the safety of all participants and dogs please adhere to this directive.
Choose from a cozy crewneck sweatshirt or trucker hat. Or get crazy and snag both items!

From Endurance Grid
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.
Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.
The half marathon rewards people who show up for the boring training miles.
How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
