Meet the 9 teams enduring '40 days of hell' in Race to Survive: New Zealand first look trailer

This summer, USA Network is giving nine teams of contestants 500,000 reasons not to quit what it's calling "the most harrowing outdoor adventure competition yet" — Race to Survive: New Zealand.

In the trailer (above) for the latest in the high-stakes adventure series following Race to Survive: Alaska, challengers must rely on a combination of endurance racing, survival skills, and intuition as they navigate 150 miles of New Zealand’s harshest terrain, or what the trailer tells us is "40 days of hell" with "no food, no GPS, no mercy" but a whole lot of blood, sweat, and tears.

"Nine teams of two will navigate the deceptively beautiful New Zealand landscape, tasked not only with sourcing their own food and water, but beating their counterparts in a race to the finish as well," the series' official logline states. The pairs must choose between the fastest route or the safest as they strive to cross the finish line before their competition to avoid being eliminated during each leg of the race. Teams will need to endure physical pain, the unforgiving environment, and one another for the chance to win a $500,000 grand prize.

The series premieres on Monday, May 20 at 11 p.m. ET/PT with a 75-minute supersized episode.

The nine teams participating include mountain climbers, smoke jumpers, river guides, and recent divorcees, among others. Without further ado, EW can reveal the full list of contestants willing to test their limits below.
