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.

For the first time ever, the Emmy-winning CBS reality series will feature a cast entirely of former 'Big Brother' houseguests, along with a loved one.

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.
