Amazing Race 19

The youngest person to sail around the world will now race around the world.

Zac Sunderland, who was 17 when he set sail alone in 2009, and his father, Laurence, are among the globe-trotting teams on The Amazing Race 19. But Sunderland is not the only established name in the cast.

Former Survivor winners and couple Ethan Zohn and Jenna Morasca will try to do one better than Survivor's original couple "Boston" Rob and Amber Mariano, who finished second on The Amazing Race 7. (They also placed eighth on All-Stars.) They join ex-Indianapolis Colts tight end Marcus Pollard, who's racing with his wife, Amani, and Olympic snowboarders Andy Finch and Tommy Czeschin.

Also on the roster are a pair of twin sisters, dating flight attendants and Vegas showgirls.

Among the twists this season: the first ever double elimination and the Hazard, which is a penalty one team will incur at the starting line.

The show also will drop by four previously unvisited countries: Belgium, Denmark, Malawi and Indonesia.

The Amazing Race 19 premieres Sunday, Sept. 25 at 8/7c on CBS.
