Originally constructed to defend China against the nomadic tribes, the Great Wall is a thrilling challenge of twists, turns, ups and downs. Beginning 4 hours north of Beijing, our challenge takes us on a serious of vigorous upwards climbs of over 10,000 relentless steps over the course of a week. As the days progress we follow the winding path along the mountains that spread either side of the Gubeikou Gateway. Exhaustion will quickly vanish as we are rewarded with sweeping views over the vast mountain ranges.
