About 20,000 participants, or "color runners," take part in the "Color Run" event, a five-kilometer, un-timed race that kicks off at Beijing Fengtai Garden Expo Park in the Fengtai District of Beijing on June 20, 2015. Some color runners use the opportunity to show their support for Beijing's bid for the 2022 Winter Olympic Games. (Photo: Chinanews.com/Jin Shuo)
