Brought to you by The Greater Yellowstone Adventure Series and CrossFit StoneFly, THE IMPOSSIBLE MILE is an Independence Day workout tradition in Ennis, Montana, engaging both residents and visitors alike. We laugh together, and cry together, as we take on versions of this famous workout scaled to our personal capabilities. Come join us and build strength, character, and common purpose. A portion of the proceeds will go to benefit the completion of a new skatepark in the local, Ennis community.
