The Curwood Festival Run is hosted by the Shiawassee Family YMCA and serves as a cornerstone celebration within the broader annual Curwood Festival—honoring famed local author James Oliver Curwood by connecting runners to Owosso’s river trails and historic downtown. With a long-standing tradition, this half marathon has become a beloved early-June tradition for the region.
The certified half-marathon (chip-timed by Michigan Running Foundation) kicks off at 8 am EDT, immediately following the 10K start. Participants run a mostly flat, fast course that blends around 50% paved roads and 50% hard-packed dirt trails—a mix praised by runners for its scenic riverside, shaded trails, and gently rolling terrain. The route follows the Shiawassee River trail into Corunna before returning through charming side streets to the finish.
Aid stations are strategically placed along the route, and post-race fun includes awards for age-groups, overall winners, YMCA-sponsored pancake brunch, and festival festivities such as a heritage parade and dog show. Community spirit shines via enthusiastic volunteers and a family-friendly environment—though pets and strollers aren’t allowed to preserve race flow.
What makes this stand out is its seamless integration into a full-day cultural celebration: you’re not just racing, you’re experiencing a hometown festival—complete with castle tours, carnival rides, and local charm.
