Emma Nicholas and Brendan Fletcher saw our post warning people off hiking the Great Wall of China.
That must have been somewhat amusing to them as they are in the middle of a 5-6 month trek along the Wall. (Walls, actually, as we learned.)
In 2002 the couple hiked the John Muir Trail, getting engaged on the summit of Mt. Whitney.
Though Brendan had hiked the Pacific Crest Trail in 1992, China is an entirely different kind of challenge.
Starting at the remote western end, their website and blog are filled with fantastic photos and insights into fascinating China.
Check it out: Walking the Wall
UPDATE:
Brendan is aware of 3 other groups travelling the Great Wall:
