Crazy Mountain 100

The Crazy Mountain 100 is an incredible ultra-running event scheduled for July 25, 2025. With approximately 23,000 ft of vertical gain and reaching heights of 10,200 ft, this point-to-point race traverses primarily single track with extreme technical descents and ascents.

The race begins at the family-owned Westling Ranch in Wilsall, MT, and finishes at the Berg Ranch in Lennep, MT. Participants will navigate through the Indigenous lands of the Apsaalooke and experience the unique landscape of these multi-generational family ranches.

This intentionally inclusive event welcomes everyone willing to accept the challenge. It promises to be a transformational experience amidst jagged cliffs, scree fields, and high alpine lakes.

Race entry is $395, with a cap of 200 runners, so be sure to register early as this race may sell out quickly!
