Black River Trail Classic
The Black River Trail Classic takes place on October 17, 2026 in Black River State Forest near Millston, WI. The 10th running of the event starts and finishes in the Smrekar Lot.
Black River State Forest was established in 1957 and covers about 68,000 acres in Jackson County. The landscape reflects glaciation from the Ice Age and includes buttes, hills, knolls, ridges and pediments. Trails run through woodlands and rolling terrain with several scenic overlooks, ridge views and fall colors.
