The Beijing Marathon saw improved performances on Sunday triggered by the increased enthusiasm for distance running in China, participants and officials said.

This year's event, which started in Tian'anmen Square, was the first time in its 35-year history that all entrants had to cover the full distance of 42.19 kilometers. The half-marathon, included for the first time in 1998, was not held.

As long-distance running continues to rise in popularity in China, it was necessary to upgrade the Beijing event from a mass-sport gala to a professional showcase targeting elite-level runners, organizing officials said.
