Coming May 18, 2013. Ready to run the Great Wall of China? Runners should expect the race to take about 50 percent longer to complete than an average marathon due to extreme ascents and descents (there is an 8-hour time limit to complete the trek). The route starts near the village of Huangyaguan, a couple hours northeast of Beijing, and heads straight to the Wall. While going up and down the steps of the centuries-old structure, you can expect stunning 360-degree views of China’s countryside. The course then heads through scenic villages and rice fields before looping back to the Wall again for the final portion of the race. And yes, there will also be a half-marathon and a 7.5km fun run.
