It is rare for a marathon to run through a factory. This half marathon in Baoding, China passes assembly workshops usually manned by factory workers and robots. But what is it like to take part in such a marathon? The chairman of Great Wall Motors, Wei Jianjun is one of the participants. His vision for the event includes a desire to expose future generations to industry, and the hope to pass on marathon spirit to his employees. As they enter the massive halls, each runner is competing against themselves, just like each automobile company competes against itself to make achievements previously thought to be impossible.
