Head to St. Regis, Montana on June 20, 2026, to run the Trail Rail Run, which offers five solo race options (5K, 12K, 30K, 50K, and 50 miles) plus team relay and hand cyclist categories for the 50-mile distance. Your journey will take you along historic, abandoned railroad grades stretching from Mullan, Idaho to St. Regis, crossing two impressive train trestles, passing through a tunnel, and running beside the scenic St. Regis River before celebrating at St. Regis Community Park with live music, food, and beer. All participants receive a t-shirt, early 50-mile registrants (by April 1st) earn a finisher's jacket, and all race proceeds go toward trail upgrades, community support, and annual scholarships.
