Lace up your trail shoes for The Willow 10 & 20 Miler on May 2, 2026, in scenic Hudson, Wisconsin. This celebrated event, organized by St. Croix Running Company, invites runners to experience the breathtaking beauty of Willow River State Park across challenging yet welcoming grass and gravel trails. Participants can choose between a single 10-mile loop or tackle two loops for the 20-mile distance, both offering diverse terrains, from runnable sections to "truly steep climbs" and "some hills" that promise to test your limits. The well-maintained, double-wide trails are mostly clear of roots and rocks, allowing runners to fully immerse themselves in the panoramic views, lush forests, and expansive grasslands, with the powerful Willow Falls providing a stunning backdrop as a highlight of the course.

The Willow 10 & 20 Miler has built a reputation for its clear course markings, supportive volunteers, and a calm, focused race environment, making it an ideal spring training milestone for both seasoned trail runners and those looking to push their boundaries. Aid stations, located approximately 6.75 miles into the loop, will keep you fueled with water, BPN GO GELs, and individually wrapped snacks. Twenty-milers will benefit from an additional aid station near the end of their first loop, complete with water, snacks, and access to drop bags. Typical race day conditions in early May feature comfortable highs around 60°F and lows around 38°F, with a 14% chance of precipitation, creating a perfect atmosphere for a memorable trail adventure.

Starting and finishing in the heart of Willow River State Park, packet pick-up is conveniently available on race morning. This cupless event encourages runners to carry their own hydration vessels, supporting a cleaner park environment. Join a community of 100-500 participants for an exhilarating journey through one of Wisconsin's most picturesque state parks, where the focus is on personal challenge and the satisfaction of a well-earned finish.
