That’s just insane!

Some of the most insane journeys in recent time include Harry Lee ‘The Hawk’ McGinnis’ walk around the world, Helen Thayer’s 4,000-mile trek across the Sahara, Andrew Thompson’s speedwalk across the Appalachian Trail (2000 miles), and others.

These along with some of the other world records (epic journeys) should give you an idea of the limits of physical human endeavor.
