(CNN) -- An ultra-marathoner trying to "run" from Florida to Bermuda in a human-powered inflatable bubble was rescued Saturday morning after he signaled for help, the Coast Guard said.
Reza Baluchi, according to his website, has set a goal of running across more than 190 recognized nations to encourage world peace. CNN ran a story about him in 2012.
The Coast Guard first encountered Baluchi on Wednesday after receiving a report about a man in a bubble off the coast of Miami, disoriented and asking for directions to Bermuda, a Coast Guard press release said. It was not clear when he started his quest.
A Coast Guard cutter found Baluchi. Officials described the craft as a "hydro pod bubble" and a man in a 2013 YouTube video called a Baluchi bubble "a big hamster wheel." It moved along the ground as Baluchi ran inside.
In the press release, the Coast Guard said Baluchi had protein bars, bottled water, a GPS and a satellite phone. The Coast Guard conveyed the voyage's dangers and asked Baluchi to quit his journey because he didn't have enough supplies. But he wouldn't leave his vessel, officials said.
The Coast Guard monitored his progress and on Saturday morning an exhausted Baluchi activated his personal locating beacon, the Coast Guard said.
