A Florida ultra-marathoner and peace activist is facing felony charges after allegedly attempting to run across the Atlantic in a homemade hamster wheel, in what authorities said was at least his fourth attempt.

Reza Ray Baluchis intercoastal stunt ended approximately 60 miles off the coast of South Carolina last week after the U.S. Coast Guard said they spotted him floating in the circular cage initially near Savannah, Georgia during routine preparations ahead of Hurricane Idalia.

The 51-year-old said he was heading for London, England, but he was repeatedly told that his vessel was unsafe and should not be in use. It was described as staying afloat through wiring and buoys, according to a copy of the criminal complaint.
