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.

Nine teams of two will navigate the deceptively beautiful New Zealand landscape, tasked not only with sourcing their own food and water, but beating their counterparts in a race to the finish as well. The duos must brave the foreign land and elements while realizing the fastest route might not always be the safest. In each leg of the race, the last team to reach the finish line will be eliminated from the competition. If the teams can endure physical pain, an unforgiving environment and each other, for long enough, they just might be able to claim the $500,000 grand prize.
