They've traveled more than 30,000 miles, gone to five continents and 10 countries, and are finally back in the United States, and now, while competing on Long Island, New York, one team will be crowned the new Amazing Race champions.

'The Amazing Race' Not 'Fixed' For A Justin/Diana Win

The Green Team (Justin and Diana), The Reporters (Kelsey and Joey) and The Paparazzi (Logan and Chris) will all head to New York for their final challenges, and while there, they will use all means of transportation as they race to be first in their most important leg of all.

However, even though their journey will end with them traversing the New York area by land, sea, and air, they will also need to get through an intense task-one which could prove to be more challenging for a strong competitor who has rarely shown himself to struggle before.

"Oh my god, you've got to be kidding me," Justin says in a preview clip for the Friday, Dec. 11 episode, as he competes in a challenge involving suiting up like a fireman and going into a burning building.

If Justin does struggle in that roadblock, it could prove to be a moment that kills all of the chances he and Diana had of tying the record of most wins during a season-and either Kelsey and Joey or Logan and Chris could shock everyone with not only a win-but the most important win of the season.

The Amazing Race airs Fridays at 8 p.m. on CBS.
