After a grueling marathon of muddy bogs, raging waters, and rocky slopes, the race enters the final stretch: an all out sprint to the Arctic Ocean. After a hair-raising ascent through the Brooks Range, the warriors must put all their experience and expertise to the test as they navigate the only path North, the daunting Dalton Highway. Rich and Carl hope to prove themselves to their Alaskan competitors by beating them on their own turf. But the Alaskan teams refuse to give the lower forty-eighters any slack, mounting an all out charge to win the prize and the title: Ultimate Off-Road Warrior.
