The Amazing Race host Phil Keoghan has told viewers to expect a fantastic seventh season of the show.

The new season will see former Survivor contestants Rob Mariano and Amber Brkich competing as a team. The pair met during the Survivor All-Stars competition, which Brkich went on to win, and have since become engaged.

However, Keoghan has warned viewers not to automatically assume that they will win the show's $1 million prize.

Keoghan told Zap2it, "A lot of time on Survivor is spent sitting down and working out what you are going to do. There's no time to contemplate like that in The Amazing Race, where you have to make decisions in the moment, on the fly, very, very quickly.

"To me, this is actually the very antithesis of their experience on Survivor, so viewers will see them reacting to a completely different experience here."

He added, "I know I said this before about race five, but I honestly believe number seven is the best race that we have ever had.

"That has a lot to do with the teams we have, and I can assure you that the show has moved back to its roots in terms of the things that made people fall in love with this show in the first place."
