Trail Rail Run
Run the old Milwaukee and Northern Pacific Railroad grades from Mullan, Idaho to St. Regis, Montana near the summer solstice. Gentle grades, beautiful scenery and moderate temperatures combine for an ultra great experience while crossing the Rocky Mountains. In keeping with our western Montana heritage, the Trail Rail Run utilizes old railroad grades from both the Northern Pacific Railroad and the Milwaukee Railroad and tracks over two breathtaking historical train trestles and dives under a beautiful tunnel. These wide railroad beds are dirt and gravel, and are never more than a 2% grade, making the Trail Rail Run a great alternative to road running. The running surface is forgiving, and the course won’t require the intensity of training that single track or steep and difficult inclines can demand.
