This 10-mile race takes you beyond the familiar park paths, plunging into a network of demanding single-track trails designed to test your agility and endurance. Prepare for a dynamic course featuring significant hills, technical terrain, and breathtaking views, including a majestic waterfall that provides a stunning backdrop to your journey.

The Trout Brook 10 Miler is renowned for offering a genuine trail race experience, perfect for seasoned trail runners seeking a fresh challenge or anyone eager to discover the less-traveled, beautiful areas of Willow River State Park. Typical race day conditions in early October offer crisp autumn air, with highs around 58F and lows near 38F, and a relatively low 13% chance of precipitation, creating ideal running weather. An aid station will be strategically placed at approximately 4.2 miles, offering water, Heed, and individually wrapped snacks to refuel, along with a restroom. As a cupless event, runners are encouraged to carry their own hydration vessels to refill at the station.

Registration opens at 7:00 a.m. near the visitor center/beach parking area within Willow River State Park, with the race kicking off promptly at 8:00 a.m.. Embrace the quiet beauty of the trails and push your limits in this highly regarded event organized by the St. Croix Running Company.
