Trail Rail Run

The June 20, 2026 event will have options of individual race lengths of 50 Mile, 50K, 30K, 12K, or 5K,  50 Mile team relay, or 50 Mile hand cyclist. The various race lengths begin along the abandoned Northern Pacific Railroad and Milwaukee Railroad grades tracking from Mullan, Idaho and ending in St, Regis, Montana. The beginning of the 50-mile course follows the historic state line. The route then tracks over two breathtaking historical train trestles and dives under a beautiful tunnel. The final portions of the course parallel and weave along the scenic St. Regis River before everyone finishes at the St. Regis Community Park with visiting, music, delicious free food and beer!

All participants will receive a t-shirt, individual 50-Mile runners will receive a finishers jacket as long as they are registered on or before April 1st. Trail Rail Run will make every effort to provide individual, 50-Mile Finishers a jacket, however, any registration after April 1st, will not be guaranteed a jacket.

Proceeds will support the further improvement of the trail, the surrounding community and the annual scholarship!
