The Trout Brook - 10-miler

The Trout Brook is a 10 mile trail race held at Willow River State Park in Hudson, WI (1034 County Highway A). The course leaves the wide park trails and moves into single track with tight lines through trees, sustained climbs, a stair section, and a waterfall along the route.

The event is scheduled in October when leaves are turning and trails tend to be fast. The course includes technical terrain and sustained distance; it is intended for runners who are comfortable on single track and uneven surfaces.

Logistics at the park: participants should park in the large lot near the visitor center and beach and pick up bibs and race items at the large picnic shelter. Park admission is required. An aid station is located at roughly 4.2 miles and provides water, Heed, individually wrapped snacks, and one restroom. Restrooms are also available at the start line and a portable toilet will be at the aid station.

This is a cupless event; runners must bring a full water container or hydration bladder and may refill at the halfway aid station. If a runner leaves the race, they should remove their bib and give it to the race director or an aid station captain; failing to notify officials may affect future participation.

The organizer states a commitment to building inclusive events. The race director may delay, suspend, or cancel the event for unsafe conditions; no refunds or transfers are allowed. Visit the organization's website for the most recent information.
