A Six Flags theme park has just rolled out a new challenge for guests to try. The spooky-themed challenge comes just in time to celebrate the park’s annual “Fright Fest” event.

According to CBS, the Six Flags park in St. Louis has created this challenge as a way to celebrate their 30th anniversary. Six people will reportedly have the opportunity to compete against each other, to see who can stay in their coffin for the full 30 hours. During the competition, contestants will be allowed a plus one to accompany them during park operating hours. However, the contestants will be alone in their coffins during non-operating hours.

Bathroom breaks will allowed at designated times, but any contestant who leaves their coffin at any other time will be disqualified. At the end of the competition, the winner will receive $300, two 2019 Gold Season passes, and a Fright Fest prize package.

Would you be able to last 30 hours alone in a coffin?
