Course
The 50K course takes runners from Big Sky Resort up into rugged alpine country, climbing steep ridges and summiting Lone Peak. Runners will traverse Headwaters Ridge, face long exposed sections with technical footing, and drop through rocky switchbacks before climbing again. The course is marked with orange pin flags and winds through a mix of singletrack, ski trails, and scree fields. Weather can swing from hot sun to snow in hours, so expect the unexpected.
