Respect where you are and give thanks…
The Crazy Mountain 100 has been a culmination of many people willing to come together and offer up access to their land and resources. 2 Family owned and operated cattle ranches host the start and finish. The Westling Ranch in Wilsall, MT hosting the start and the Berg Ranch hosting the finish in Lennep. These two multi-generational family ranches will give you a first hand look at quality care of the land they operate in the valley.
The race course itself navigates through the Indigenous lands of the Apsaalooke, private, and public land/forest service. To the Apsaalooke people this range is called Awaxaawippíia. “Awaxaawi” Meaning Mountain. ppíia” meaning ominous or angry. Some say you can hear the mountains and the power is felt. We feel this is an important history and knowledge. Our hope is that you take the time to learn about its’ rich history.
We are an intentionally inclusive event that welcomes any and all people willing to take on the challenge. Our goal is to bring you to this wild, sacred, and unique place, and have you leave forever changed. You simply cannot experience the jagged cliffs, scree fields, and high alpine lakes, without experiencing something deep within your soul. This is sure to be the craziest race you have ever attempted.
Berg Ranch- Finish
Lennep, MT
The Berg Ranch, near Lennep, MT is situated between the Castle and Crazy Mountains. It was homesteaded by Jakob Berg, a Norwegian immigrant who was one for the first settlers in the valley. He had a butcher shop in a near by mining town (Castle Town) and eventually moved down the valley and began a long legacy of ranching on this land in 1890. The ranch began as a sheep ranch, but in the mid 1900s, transitioned to beef cattle, now raising primarily Red Angus cattle. Since being established in 1890, the ranch has remained in the family and is now operated by the 5th generation, Kari and Charlie Marks. Each generation on the ranch has had a deep reverence for the land and their role in stewarding through to the next generation.
Westling Ranch- Start
Wilsall, MT
John Westling came from Sweden in 1902 to Helena, MT. He soon after ventured out to Wilsall, MT and built the Westling Homestead. The Ranch has grown over the years and is still owned and operated by the Westling Family. Today it is on it’s 4th generation and continues to provide a marvelous living for the family. Over 14 family members have been raised on the ranch. Come see for yourself the beautiful ranch as this is the start of your 100 mile adventure!
