Reza Baluchi, who has in the past run around the Unites States and bicycled across nearly 60 countries, attempted a new long-distance endeavour last week by attempting to walk the almost 1700 km from Florida to Bermuda. He was going to walk across the ocean in a homemade "hydro pod," propelling it by running and pushing it with his arms. Think of it as a human hamster wheel.
Last Wednesday after only travelling about 130 km, the US Coast Guard checked on him, but let him continue, but by this past Saturday, he had made little further progess and activated his rescue beacon. He was rescued by the Coast Guard, exhausted but apparently otherwise uninjured.
Here's a video of the hydro pod in action:
