Ronald Hsu & Christina Hsu, TK Erwin & Rachel Rosales and Nicolas Fulks & Donald Jerousek are the three teams racing for the top prize of one million dollars. They take off from their Pit Stop at the Chiang Kai-Shek Memorial Hall Plaza in Taipei, Taiwan and receive a clue instructing them to immediately fly to the final destination city of Anchorage, Alaska, over 4,500 miles away. As teams scramble for flights, all obtain the same flight, but one manages a valuable upgrade. Once in Alaska, teams travel to 6th Avenue Outfitters, an adventure store, to pick up vital gear for tasks and a clue. One team, however, neglects to pick up their gear and does not realize their mistake until reaching the Detour. This particular Detour, at the Ship Creek Boat Launch, requires teams to choose between tasks involving either cod or crabs. The teams then taxi sixty miles to the Twenty Mile River and then take a high-speed boat ride to the Twenty Mile Glacier, which they scale. Next, teams take a thrilling taxi ride across the Alaskan wilderness to Merrill Field and taxi to Goose Lake Park. There, they face the final Roadblock, in which one member of each team is required to complete a task that involves the placement of various objects featured throughout the race. Teams then receive two clues instructing them to travel to statues, and then finally are instructed to travel to the Girdwood Airport and run to the finish line. In a near-photo finish, one team just ekes out another to win The Amazing Race 12 and claim the one million dollar prize.
