Brookfield Classic

Brookfield Classic takes place in Brookfield, New York, on September 19, 2026. Three trail formats are on the same day's program: a 50K (31 miles), a 15K (9.3 miles) and a 5K. The organizer's website points to Co-Movement. Brookfield is in central New York, in an area known for its extensive trail network.

Choose your distance according to where you are in the season. The 5K makes the event open to beginners and families, the 15K is a satisfying midlength trail race for runners moving up from a 10K, and the 50K is a good choice for a first ultra or a late-season long effort before the winter break. If you go for the 50K, a 16-week build with a weekly long trail run, back-to-back long weekends in the final month and rehearsed fueling will keep the day under control. Whatever the distance, get used to running on dirt and grass in the weeks before, as trail footing slows most road runners more than they expect.
