So hard to call the winner of this one

Based on edits I think it will be either the gay farmers of the two James; Farmers have the under dog edit which might turn out to be a surprise win, while the two James keep mentioning how much this will change their life's if they win.

Based on the end trailer for the final episode

Spoiler:

Basically we see Lexi doing the final roadblock where they have to I guess match the hello and goodbye to each country (If you notice all season they have shown the person at the pit stop saying hello and goodbye); so we Know Trey and Lexi are in the final 3

Also I saw a clip of the two James running down a path (Cant remember if they had bags); this might be possibly them running to the finish line?
