The annual spring running meet has been a traditional sporting activity in the capital city ever since its launch in 1956.
With the participation of Lv Bo and Yang Yilin from the Chinese Gymnastics Team to cheer the runners on, the festival provides a stage for amateurs to amuse themselves through running.
An American girl who called herself Sina said she never expected that she could take part in such a jubilant event after arriving in China six months ago.
"I've done one in the United States, but none in China before. I'm very excited. I love running. I love excitement. I've never seen so many excited people in Tian'anmen Square. It's great."
