Has anyone ever walked the entire length of the Great Wall of China?

The above answers are both correct and incorrect. It's true that the wall is broken in places, but it HAS been walked in its entirety.

When i lived in Shanghai i met a guy whose brother from South America (i think Chile, but can't remember) walked the wall.

He documented the entire trip with pictures. The journey began with him and 4 other friends, but he was alone for 9 months of the 15 month trip!

So, yes, it has been done. But i would assume only once!

Yes!
I imagine after it was built many people walked it from end to end, eventually. It was a marvel in its time and still is. After its started to deteriorate I doubt it. However in its over 1000 years of existence I am sure someone was walked the whole thing.
I visited the great wall last year. No one has ever walked the entire length of the Great Wall. The wall is not continuous. There are sections that go for a 100 miles, then just stop completely. Then start up hundreds of miles away again. Also, much of the wall is in total ruins. Even on 5 miles I walked on, there were times when the wall was so ruined that we had to climb down and walk along side it for a few hundred feet before it was ok to climb back on.
