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.

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.

The competitors kick off the season in Amsterdam where they face classic game pieces and unexpected twists right off the bat. For the first time in the show’s history, teams face their first challenge before even lining up on the starting line.
