How deep is your love? Six feet, maybe? For this year’s Fright Fest 2019, Six Flags America is challenging couples 18 and older to a claustrophobic test of endurance by seeing if they can spend 30 long hours together inside of a 65-inch by 72-inch coffin. Those who make it through will win $600 dollars to split, a pair of Gold Season Passes for the 2020 season, and a Fright Fest Prize package.

In addition to spending 30 straight hours alongside a friend or partner, coffin dwellers will be required to participate in extra challenges that will test their bravery.

The 30-hour couples coffin challenge will take place at Six Flags America in Bowie, Maryland

The challenge will begin at 4 p.m. on Friday, September 27, and will end at 10 p.m. on September 28. The coffins won’t actually be buried beneath the ground, but after lying in a box for 30 hours with the lid closed, it may begin to feel like it.

The unlucky duos selected to compete are allowed to bring one friend during Fright Fest hours, but they will have to leave all smartphones, smartwatches, gaming devices, and all other technology out of their temporary resting place. Smoking is also not allowed.

According to the official rules, eating, checking social media, and sending emails to update the outside world on the status of your pulse will be allowed during designated breaks. During the breaks, the coffin lid will be opened and the contestants will be allowed to sit up, but they cannot leave their wooden beds. There are required six-minute restroom breaks every three hours, but any couple that leaves the coffin outside of those breaks will be disqualified.

Six Flags America warns that participants will "potentially be exposed to fog, dramatic lighting, flash photography and extreme weather conditions," and that the rules may be altered for the safety of the contestants.

The couples element (loosely defined as two people) is a new addition to the challenge

Six Flags held its first "30-Hour Coffin Challenge" in St. Louis, Missouri, last year. All of the contestants won, but it wasn't easy. They had to deal with cold weather conditions and had to sprint to the bathrooms to make it back within the six-minute time limit. They also had to lie in the coffins with the lids open for the duration of the challenge, which came with its own challenges.

"The open-top was brutal," said a contestant named Brian Johnson. "Lights everywhere, people talking, you could barely sleep."

So, how will it be in a closed coffin with another body next to you? Registration ends on September 20 at 11:59 p.m. EST, so hurry over to the Six Flags America contest page if you want to find out firsthand.
