After battling a temperamental engine over wide-open ocean, Marcio and Kerry decide it's time to get some open water survival training. They brave the cold Icelandic water and get a reality check in surviving a ditch. Pete and Cory get their own reality check when they arrive in the Arctic sporting dress shoes and light jackets. The town's very own super-hero, Polarman, is there to set them straight.

With almost 8,000 kilometers behind them, Pete and Cory face intense headwinds and a dwindling fuel supply. Pete challenges Cory to make the call – turn back or keep going? In Greenland, Marcio and Kerry are going nowhere fast. A bureaucratic mix-up could force them to backtrack 1,000 kilometers. While they cool their heels, Marcio the foodie reluctantly dines out on some local cuisine… whale blubber.

Kerry and Marcio are in the final stretch of an 11,000 kilometer journey. Marcio has strict orders to make it home on time to his very pregnant wife. But Kerry has other ideas, that include a pit-stop at his hunting cabin for a little downtime with his buddies and steaks on the BBQ. Over in Iceland, Pete and Cory are paying for a wild night out with the locals. They need to make up time. But Pete can't resist an opportunity to check something off his bucket list.
