The entire wall measures over 13,000 miles and going up this thing is a great feat. It’s so vast that even Justin Bieber had to be carried upward by his bodyguards.

Varying reports suggest that it could take a reasonably fit person an average of two to four months to walk the entire length of the Great Wall. We don’t recommend doing this, though.
