So, we are organizing this marathon for the sixth time, with the aim to encourage people to play sports and follow healthy lifestyle habits," Shijirbaatar Ankhmaa, deputy mayor of the Mongolian capital, told Xinhua during the marathon.

Over 30,000 people aged 2-87 from 29 countries and regions competed at six categories, including half marathon, full marathon, family marathon and wheelchair marathon.
