The Trout Brook

The Trout Brook is a trail race held in Hudson, Wisconsin, on October 10, 2026, starting at 8:00 a.m. Organized by St. Croix Running Company, the event offers a single format, a 10 Miler (16.1 km).

Ten miles is an underrated distance: long enough to reward endurance, short enough that you can run it with intent from start to finish. On trails in the St. Croix River valley in mid-October, you can expect rolling terrain, fallen leaves and crisp temperatures, which makes it an attractive tune-up race before a late-fall half marathon, or a satisfying goal in its own right for a runner who wants to move beyond 10K. A 10-week plan is enough: three to four runs per week, a long run building to 9 or 10 miles, one weekly session of tempo running or hill repeats, and at least one run on trails to get used to changing footing. Trail shoes with grip will help if the ground is wet, and a light layer you can remove after the first mile is worth having for an 8:00 a.m. start.
