Lace up your trail shoes for The Trout Brook, a challenging 10-mile race on October 10, 2026, in the stunning Willow River State Park, Hudson, WI. Organized by the St. Croix Running Company, this event is renowned for its demanding yet rewarding course, perfect for experienced trail runners or those eager to delve into the park's less-traveled areas. Runners will navigate a course that trades wide-open park paths for technical single-track trails, featuring significant hills and breathtaking views, including a majestic waterfall. While a famous stair climb has been removed due to damage, the "serious terrain" promises to test your skills and push you out of your comfort zone.

The race kicks off promptly at 8:00 a.m. near the registration area, which is situated at a large picnic shelter by the visitor center and beach. Participants should arrive early to allow for park admission and parking. The race champions environmental responsibility as a cupless event, requiring runners to bring their own water containers or bladders for refills. An aid station, stocked with water, Heed, and individually wrapped snacks, along with a portable restroom, is conveniently located around the 4.2-mile mark to keep you fueled and hydrated.

With typical race day conditions boasting highs around 58°F and lows around 38°F, and only a 13% chance of precipitation, runners can anticipate crisp autumn weather ideal for a rigorous trail experience. Many participants have lauded The Trout Brook as a fantastic event with a beautiful course, appreciating the serene atmosphere, especially towards the back of the pack. Prepare for an exhilarating journey through pine forests and diverse terrains, culminating in a truly satisfying trail running accomplishment.
