About The Obstacle Course

The course is 11 lanes of obstacles and approximately 25+ obstacles of varying difficulty. Everything is “challenge by choice” so if you do not feel comfortable trying an obstacle, you don’t have to! This course is grass, NO MUD, so you won’t likely go away dirty unless it is raining or has been wet. There is also a nice 1/3 mile running loop, also mowed grass. The course is beautiful!

No Gimmiks


This course has no gimmiks–there is no mud, no shocking, smoke or fire, no freezing water, and no inflatable obstacles. Every obstacle is “challenge by choice”, meaning *you* get to decide how easy or tough the course will be for you. We have trained all ages–from the Girl Scouts at age 5, to the Army Reserve, to women and men in their 60’s!
