CBS has unveiled the cast for the 13th edition of its Emmy-winning The Amazing Race, and it's a typically eclectic bunch.

Among this cycle's competing teams are former NFL star Ken Greene and his estranged wife Tina; a Dallas Cowboys Cheerleader and her actor brother; a pair of nature-loving seniors; two fraternity brothers who come to be dubbed "Team Superbad"; the treasurer for Comic-Con and his best bud; a college kid and his single mom; and a pair of blonde Southern belles.

Executive producer Bertram Van Munster tells the AP the coming season will include a series of TAR firsts, including a mistake that keeps one team from crossing the finish line, as well as a memorable stop in Cambodia.

The Amazing Race 13 gets going Sept. 28, at 8 pm/ET. - Matt Mitovich
