Madonna is pushing her limits, boldly going where no music diva has gone before! CLICK HERE for the story.

Personally, I doubt she'd last a day out there. I doubt her ability to compete on tired legs the 2nd and 3rd day, let alone the whole 156 miles. Let her do a 50 miler first. Let her make another good album....that would be good! It's kind of cool in a way that ultra running makes the entertainment news though.
