Course Information

One Tough Cookie is back on June 1, 2019! 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.

One Tough Cookie is designed for runners ages 14 and older, but tough cookies under 14 don’t stress! One Tough Cookie Jr. provides runners ages 8-13 a challenging course that includes some of the adult obstacles. Muddy Buddy is a super fun and simple for kids ages 7 and under who love lots of mud. Adults who want to run One Tough Cookie Jr. with their child must register and complete the necessary waiver. Adults who want to run Muddy Buddy with their child do not need to register, but are welcome to sign up and receive a 2019 One Tough Cookie shirt.
