With Ben and Adam's plan in shambles, they're going to need a stroke of luck to recover; meanwhile, Sam and Joseph realize that "putting all the effort into crossing the Atlantic" is not a viable strategy.

Both teams start the race at Union Station in Denver, Colorado. They have 100 hours to make it back to the flag pole, whichever team makes it first wins the crown.

Both teams end up in the same country as the game tightens, who will make it back to Denver first?

Ben and Adam make fiscally responsible decisions, while Sam and Joseph risk it all on a big play.

Big plans and a lot of luck decide the winner in the finale of their race to circumnavigate the globe.
