In the most harrowing outdoor adventure competition yet, challengers must rely on a combination of endurance racing, survival skills and intuition as they navigate 150 miles of New Zealand's harshest terrain. From the depths of ancient caves to frigid alpine summits, every step and every calorie is hard-earned. However, strength and speed alone won't be enough to win $500,000. Rather, only those with the strongest will to survive can claim this life-changing prize. 

Set along the wild and dangerous Alaskan coastline, adventure racers and survival experts must endure more than 100 miles of inhospitable terrain with nothing but what they can carry to claim a life-changing $500,000 prize. Contestants must utilize a combination of endurance racing, primitive survival skills and bushcraft as they navigate the mostly unchartered wilderness with sprawling mountain ranges, ancient glaciers, threatening wildlife and suffocating rainforests. The stakes couldn't be higher for the teams as they race across unforgiving land in the ultimate test of person verses nature, where winning is the goal, but survival is the challenge.
