Prospector’s 50K & 30K Silver Gate, MT   Aug 8–9, 2026

Aptly named for the rugged men who explored this area starting in the 1860s, the Prospector 50K & 30K will feature views as good as the gold they were looking for. If you can pull your eyes away from the surrounding mountain views, you’ll run by big and small reminders of the mining activity including homesteads, mine equipment, and endless spur roads.

The 50K course will start in Silver Gate and finish in Cooke City following access roads and trails and gaining approximately 5,500ft. The 30k course follows the majority of the 50k course.

Limited to 100 racers per event.

Not for the faint of heart. This race will have a 12 hour cutoff time with each aid station having progressive cutoffs. If you make it to an aid station after the cutoff time you cannot continue the race and no refunds will be issued.

The Prospector 50k/30k races operate under a Special Use Permit from the Gardiner Ranger District.
