From the New York Times bestselling author of The Impossible First, a compelling blend of riveting adventure stories and hard-won wisdom that reveals how you can harness your inner strength, overcome your limiting beliefs, and embark on a transformative, one-day journey that will unlock your best life.

Millions of people dream of living a more fulfilling life, yet many of us settle for a life of comfortable complacency and quiet desperation, allowing excuses and negative thoughts to invade our mindset. What if I fail?...I don’t have enough money…I don’t have what it takes—we allow these voices to run our lives.

Now, The 12-Hour Walk provides the inspiration and catalyst for getting unstuck. Featuring the hard-earned life lessons of ten-time world record breaking explorer Colin O’Brady, with captivating stories set to the most extreme places on Earth—from Antarctica to the perilous Drake Passage to the peaks of Mt. Everest and K2—this book shows us how to embrace our abilities, step out of our comfort zone and embark on our own life-changing personal journey.

With Colin as our guide, The 12-Hour Walk asks us to invest one day in ourselves. The reward? Unlocking our best lives and embracing our full potential. By walking alone, unplugging, listening to the voice within, and rewriting the limiting beliefs that are etched into our psyche, we can break free of the patterns that hold us back and cultivate a “Possible Mindset.” The 12-Hour Walk gives you the wisdom and confidence to become the hero of your own destiny.
