Once in Motor City, Tyler, Leo and Colin volunteered to rappel down landmark skyscraper The Guardian Building all while memorizing a series of numbers that made up the combination to open a bank vault. Despite Colin's speedy completion of the road block, he and Christie ran into trouble locating their taxi while en route to their next challenge.

Tyler and Korey were first to arrive and complete a game of "Fowling," a combination of football and bowling unique to the city of Detroit. Next up, the remaining teams found themselves making records at Third Man Records, an independent label founded by The White Stripes rocker and Detroit local Jack White. Meanwhile, Leo struggled to open the bank vault and he and Jamal fell far behind their fellow competitors. 

Keeping on theme with all The White Stripes references, the teams (at this point led by Christie and Colin) were asked to assemble a drum kit while a massive band performed "Seven Nation Army" over and over and over again. 

In the end, Christie and Colin literally called on their "angels and guides" to help telepathically guide them to completing the task—and it worked! They were the first team to cross the finish line and win the $1 million.

Tyler and Korey finished in a close second, followed by Leo and Jamal. 10 countries, 18 cities, and more than 25,000 miles... we (well, they) did it!
