The Unbreakable 24 Hour Challenge, like all of the teachings developed by retired Navy SEAL, Thom Shea, is an experiential based learning event. With a concentration on both mental and physical aspects of performance, it involves walking for 24 hours with a group of participants while being led through a series of lessons delivered by Thom himself. Some consider this the most powerful lesson in Thom's book, Unbreakable: A Navy SEAL's Way of Life.

Are you ready to push beyond your self-imposed limits? Join us for this event and experience performance breakthroughs in all areas of your life. Past participants have set a new standard for what is possible in their lives and have gone on to accomplish goals that seemed unattainable in the past.

WHAT is involved? As in all endeavors, preparation is key. We strongly suggest you complete the four week training program included with your registration. We provide a comprehensive gear/nutrition list to ensure the highest likelihood of success, speediest recovery and as much comfort as possible during the event. The challenge is to walk for 24 hours in order to overcome your self-imposed limits. This is predominantly a mental challenge. Although physically demanding, you do not need to be a master athlete. The challenge is designed to create an environment for you to honor you word and for you to face the mental obstacles that get in your way. The experience is the very definition of "Simple But Not Easy." You will have the opportunity to have your mind instead of your body control your actions during times of discomfort to push past your self-imposed boundaries. Upon completion, participants note a meaningful shift in what is possible in their lives. The course is a series of two to three hour loops on various trails. The trails are not technical and do not present elevation challenges. You will stage all of your food and drink in your vehicle. There are clean restroom facilities near the parking area.

WHO participates? People ages 18 through 82 who are willing to learn what it takes to push through self imposed limits and have an Unbreakable Life.


Registration includes our 4-week training program and comprehensive gear list. The Course is a series of “out and back walks” along trails and roads.  You will stage all of your food and drink in your vehicle.

"You need to adapt just like all the other things that can make you quit every day. I had an amazing experience...a lot of things are more clear." Frank

"Thom, thank you for being the inspiration of all of us taking on this challenge and teaching us to control our negative thoughts when things get tough and our mind tries to make us quit. Friends are priceless and doing things together like this helps us to grow as individuals and become better friends and through all of this helps us to be better and stronger in all phases of our lives!"
