The gaps between teams continue to widen. The last teams finally arrive in Dawson City as the first teams reach Eagle, Alaska. The tiny isolated village has no road access in the winter so handlers must take a 24 hour detour to meet their teams at the next checkpoint. Two more teams scratch at Eagle, but without road access their dogs must be evacuated by plane. Only 16 teams remain. Mushers begin to make mistakes as sleep deprivation sets in. Leader Brent Sass stops on the trail for a short nap and sleeps away 9 of his 10-hour lead. Will it cost him the race? The second half of the trail holds even more dangers than the first including the infamous Eagle Summit. Who will ascend the summit and who will fail?
