A 50k solo and 3 person trail run going from Bogus Basin Ski Resort to the historical mining town of Idaho City. The course runs along forest service roads and ATV trails in the Boise National Forest, giving runners fantastic views of surrounding mountain ranges as well as granite rock formations in the area.
Note that this is a fat ass, that means no entry fee but also no real support. There will be 2 water drops on the course around miles 10 and 20 beyond that you are responsible for any support or aid you may need as well as transportation back from Idaho City. See the Facebook page for route maps and more information.
