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.
