Whitney Duncan is set to compete in the next season of CBS' 'The Amazing Race.'

The singer and former 'Survivor' contestant will compete alongside her fiance and fellow 'Survivor' contestant Keith Tollefson.

“I’m smart, physically fit and not afraid of anything,” she says. “I’m extremely competitive and love to win.”

This season marks the 25th worldwide trip for the show, which kicked off May 31 in New York City's Time Square. In addition to Duncan and Tollefson, competing couples include a pro wrestling couple, food scientists and urban bike racers.

The new season of 'The Amazing Race' premiers Oct. 30 at 8PM ET on CBS.
