This run should only be attempted by those who are trained to do power running. The run follows the continental divide in a northwesterly direction near the Montana border. The trail is a singletrack with some strenuous grades, and it gets more difficult the farther north you go. It starts out fairly easy, so there is an option to plan a shorter out and back trip. There are some amazing views from the trail, a rock garden, and plenty of wildlife. If you plan on camping, a wilderness permit can be obtained from a Forest Service facility or a registration box.
