Seventeen pairs of best friends, exes, couples and siblings will be put to the ultimate test on The Challenge: Ride or Dies, premiering next month on MTV. 

While the partner concept is nothing new for ‘The Challenge,’ Season 38 marks the first time players will pair themselves up to compete alongside their closest ally, Variety reports. 

Throughout the competition-– filmed in Argentina–- the duos will “navigate the weekly mental and physical warfare together for their share of $1 million,” according to MTV. 

“These relationships will be put to the ultimate test as their teamwork, loyalty and trust will be challenged every step of the way,” the network’s press release states. “In this game, it all comes down to who you trust and who has your back, because this season of ‘The Challenge’ will either break bonds or tie two competitors together for life.”   

Returning to host this season is TJ Lavin, who makes it clear in the preview that each competitor will need the support of their ally to make it to the end. 

“Luckily for you, you got to bring your own,” he adds.  

Despite each player going into the competition with a trusted companion on their side, things can still get messy and teams may still crumble under pressure.   

“They’ll ride into the competition together, but will the game tear them apart?” the trailer asks. “The competition has never been this personal.”
