The Copper Kings 100 transforms Butte's historic trails into a 100-mile celebration of endurance, community, and conservation. Our signature event brings together runners of all abilities to experience the Continental Divide Trail while supporting local nonprofits and showcasing Montana's natural heritage. More than a race, it's a movement that proves every mile matters when we run for something bigger than ourselves.

Montana Endurance Trail Foundation is a Montana nonprofit corporation and a recognized 501(c)(3) tax exempt organization.
