Over the course of thirty-two seasons, The Amazing Race has seen many teams race around the world in an attempt to win one million dollars. A popular casting choice the show loves to make is casting fan-favorite teams from other reality shows, particularly CBS reality shows. As a result, many teams originally competed on shows such as Big Brother and Survivor.

Big Brother has seen the most teams cross over to The Amazing Race with Big Brother legends, fan favorites, and memorable showmances getting a chance to race around the world. The teams have varied in their success on the race, but one Big Brother team managed to win it all.

Alison & Donny

The first Big Brother contestant to cross over to The Amazing Race was Alison Irwin. She competed on the fourth season of Big Brother and dominated the game with her ally, Jun Song. While she made it to the final two, the jury ultimately decided to award Jun with the win.

Alison then participated in the fifth season of The Amazing Race with her then-boyfriend Donny Patrick. While they finished first on the first leg, Alison and Donny's constant arguing with one another caused them to drop to last place in the second leg. Ultimately, they became the second team eliminated from the race, finishing in tenth place.

Jeff & Jordan

One of the most popular showmances in Big Brother history, Jeff and Jordan continued their newly formed relationship by crossing over to The Amazing Race. Jeff and Jordan first competed on Big Brother 11, where Jordan went on to win the game. They returned for Big Brother 13 as a duo where Jeff finished in seventh place and Jordan finished fourth.

In between seasons, Jeff and Jordan competed on The Amazing Race. After a good start, they finished first on the first leg, but then lost steam as the recency of their relationship began to show. They were eliminated in seventh place and remain one of the more forgettable Big Brother teams to run The Amazing Race.

Nicole & Victor

Nicole and Victor first met on Big Brother 18, but they only started dating after the show as Nicole spent the entire game in a showmance with Corey. During the game, Victor proved to be a competition beast, and Nicole managed to get to the final two and beat Paul in a 5-4 jury vote, securing her the win.

After their engagement, Nicole and Victor competed on the thirty-first season of The Amazing Race and proved to be a strong team. However, they ended up making enemies of fellow Big Brother players Rachel and Elissa. Plus, Nicole's paranoid personality and constant crying made her an unlikable presence. Regardless, Nicole and Victor finished in fourth place overall.

Rachel & Elissa

A popular contestant among Big Brother fans, Rachel Reilly competed on Big Brother 12 and Big Brother 13, winning the latter season. Her sister, Elissa, would then compete on Big Brother 15, finishing in 6th place.

Rachel would return to race for her third time on the thirty-first season of The Amazing Race, but, this time, she would race with her sister. The team started off strong but quickly made enemies when they tried to warn Nicole and Victor they were potential U-Turn targets, resulting in Rachel and Elissa finishing in seventh place. Regardless, Rachel was able to receive the distinction of finishing the most legs out of any female contestant in Amazing Race history.

Janelle & Britney

Consisting of two Big Brother legends, the team of Janelle and Britney was a fan favorite duo for Big Brother fans. Janelle became known for her competition prowess in both Big Brother 6 and Big Brother 7, while Britney was a diary room queen in Big Brother 12. Both would return as coaches in Big Brother 14, marking the beginning of their friendship.

Janelle and Britney competed on the thirty-first season of The Amazing Race, but, unfortunately, had bad luck and struggled with directions, causing them to remain in the back of the pack. They ultimately were eliminated in eighth place, but their fun personalities make them a likable and entertaining team among fans.

Brendon & Rachel

Brendon and Rachel met on the twelfth season of Big Brother, becoming one of the most polarizing showmances in Big Brother. Rachel's overbearing personality caused plenty of drama throughout both of her Big Brother seasons, irritating both fans and fellow contestants with her constant emotional outbursts. Regardless, she remains an entertaining reality personality that garnered a large fanbase.

Brendon and Rachel would compete on The Amazing Race twice. Their first time was during the twentieth season, and they returned for the twenty-fourth season, which was an All-Stars edition. Brendon and Rachel proved to be just as irritating and polarizing on the race as they were in the Big Brother house, as many teams disliked them. However, Brendon and Rachel performed well together, finishing in third place in both seasons they competed in.

Cody & Jessica

Cody and Jessica first met on Big Brother 19, getting into a showmance and becoming major threats within the house. When Cody tried to make a move against returning player, Paul, the couple was placed on the outs and became the targets of Paul and his minions' constant bullying.

The couple then went on to compete on the thirtieth season of The Amazing Race. Cody and Jessica dominated the majority of the race, finishing the race in first place and claiming the million-dollar prize. Currently, Cody and Jessica are the only Big Brother team to win The Amazing Race, an impressive feat.
