Course Information

One Tough Cookie is back on June 6, 2020! This 3+ mile mud run and obstacle course creates a challenging, but super fun atmosphere, where runners of all backgrounds can have a good time. One Tough Cookie is held at Camp Liberty in New Liberty, Iowa, so expect natural features to become elements of this course. Rolling hills, wooded trails, and Flint Lake make this run unique… and the not so natural obstacles might include a slip-n-slide.
