This Ultrarunner Is Living in a Glass Box for 15 Days

During the experiment, Krasse Gueorguiev will have only a bed and a treadmill

Krasse Gueorguiev, a Bulgarian ultramarathon runner, will spend 15 days in a glass box in a park in Sofia, Bulgaria, to raise money to help young people battling addiction.

Gueorguiev, a motivational speaker and charity ambassador, has run nearly 30 ultramarathons worldwide, from the Arctic to Cambodia, including the 135-mile Badwater Ultramarathon in Death Valley, California.

"I want to challenge myself," Gueorguiev told Reuters. "I want to show when you put someone in the box how psychologically they change."

Proceeds from the stunt will be used for several projects aimed at preventing addiction for children under 18, not just for drugs and alcohol—the runner also hopes to help teens avoid addiction to things like social media and energy drinks.

On Sunday, the runner was placed in a box with three glass walls on a pedestal in front of the National Palace of Culture in Sofia (Bulgaria's capital). During the experiment, Gueorguiev will have only a bed and a treadmill, with no access to books, a computer, or a phone. He will only be allowed to speak to members of the public for 30 minutes each day.

"This is not a physical experiment; it is a psychological experiment," he said.

If the stunt sounds familiar, you may remember magician David Blaine undertaking a similar experiment in 2003. The illusionist spent 44 days in a glass box suspended over the River Thames in London. 

The stunt was met with much public outcry, though, unlike Gueorguiev, Blaine's time in the box was for entertainment purposes only. He endured drumming from the crowd in the evening hours and having eggs and other items hurled at his temporary home. The magician seemingly took it all in stride. "I have learned more in that box than I have learned in years. I have learned how strong we are as human beings," Blaine told reporters after emerging from the box. Upon completing the 44 days, Blaine was noticeably thinner, with depleted muscle mass and a thick beard. 

Only time will tell if a similar fate inside the box will befall Gueorguiev.

This is also not the ultrarunner’s first attempt at performing a stunt in the name of goodwill. In 2019, Gueorguiev ran about 750 miles through Bulgaria, North Macedonia, and Albania to urge the governments to build better infrastructure, and in January of 2018, Krasse ran for 36 hours straight on a treadmill at a Sofia shopping mall.
