What a crazy record:

A man runs for 24 hours non-stop on a treadmill! On April 12^th, 2007 in Santiago City, Chile, Erwin Valdenbito covered a distance of 153.9 miles.

Not funny enough?

Look at this unique world record: Ron Sarchian (USA) got the idea of hitting a punch bag for as long as he could - he did it for an incredible 36 hours and 3 minutes!
