The trash talk is going down before ‘The Amazing Race’ has even started in this sneak peek [WATCH]

When stars collide from CBS’ three marquee reality shows, you can bet there’s smack talk about whose show is tougher/better/the best. That’s precisely what happens at the starting line on “The Amazing Race 31,” the reality showdown installment between “Race,” “Survivor” and “Big Brother” alums.

In a sneak peek (watch above), Phil Keoghan, touting the “first ever showdown” between alums from the three shows, asks who has the edge over the others. He knew exactly what he was doing with that one.

“Oh, the Survivors do!” Rupert Boneham shouts. “The Survivors in general are very tough.”

Naturally, the racers weren’t going take that one sitting down on their own turf. “We’re not sitting on an island for 40 days; we’re running around the world,” retorts JJ Carrell, who’s racing again with his border patrol agent pal Art Velez.

Keoghan makes sure to point out that Rachel Reilly is the only “Big Brother” or “Survivor” alum who’s done “Race” —  and she did it twice — which also immediately puts a target on her and her sister Elissa Slater‘s back. Rachel, who won “Big Brother 13,” thinks the former houseguests are in a rude awakening on the “Race” course because they just sit around and eat all day in the house, whereas you’re constantly on the go and hardly eating on “Race.”

“We literally never eat on ‘Survivor,” Eliza Orlins says.

Yup, this is how it’s going to be.

The clip also includes a preview of the first task: They have to dig through an octopus sculpture in the sand to find their first clue, which (spoiler alert!) will direct them to Japan.

“The Amazing Race 31” premieres on Wednesday, April 17 at 9/8c on CBS.
