"The Amazing Race"'s final three teams -- Nat and Kat, Jill and Thomas, and Brook and Claire -- soar to new heights over Southern California, as they compete in the final leg of their journey for a shot at the $1 million prize. Now, ET has your sneak peek.
Jill and Thomas are in first place as the final competition begins, but their competitors are no slouches. If either of the other teams beats Jill and Thomas to the finish line, it will be the first time in "Race" history that an all-girl team wins.
Of course, Brook and Claire made headlines with the watermelon shot heard around the world when Claire was hit in the head with a watermelon during a medieval challenge gone wrong.
"The Amazing Race" finale airs Sunday, Dec. 12 at 8 p.m. on CBS.
