The Amazing Race season 38 cast was officially announced in August 2025. In all 13 pairs, at least one person competed on the hit surveillance show, Big Brother. Before filming started, the contestants were unaware they'd compete against their fellow Big Brother alums.

CBS has unveiled the official photos for the Big Brother alumni competing on The Amazing Race Season 38, premiering on Thursday, September 25 at 9 p.m. ET. Phil Keoghan returns to host the competition, which sees 13 fan-favorite housemates embark on a European adventure with their travel companion.

Big Brother has had a presence on The Amazing Race ever since BB Season 4 runner-up Alison Irwin appeared on TAR Season 5 with her then-boyfriend. And, over the past 20 years, multiple former houseguests have made their way out of Studio City and onto the plane for a life-changing globetrotting million-dollar journey.
