Running the world

First, China's rising prosperity and its people's concern for health and fitness are unlikely to fade.

Second, the underpinnings for marathon mania have grown rapidly: Wang Dawei, of the CAA, says Chinese marathon officials frequently interact with and learn from foreign counterparts; foreign runners are coming to China; social media and traditional media built around running, such as the slick magazine Frontrunner, have become well established; and businesses are investing in the sport.

Third, and perhaps most important, are the young runners who aspire to take on international marathons.

The running bug bit Zhang Yiming, 20, a junior at Renmin University of China's School of International Relations in Beijing, in December 2014. At first, it was just a way to lose weight and stay healthy. She ran her first half-marathon in April 2015 and has been participating in races around China since then.

She runs 8 kilometers two to three times a week, which she says helps her deal with stress and keep calm.

Zhang says she plans to run two international marathons a year, with New York, Boston and Munich at the top of her wish list.

"I can't afford running abroad yet, but I'll definitely put my feet down in countries all over the world in the future. That's my dream, and it's my motivation to keep moving."
