It was the most serious level on China’s air quality index and came with a warning for everyone to stay indoors and avoid outdoor activities.However, the marathon’s organizing committee said that postponing the event would be difficult because it was impossible to change all the planning.According to the World Health Organization, daily pollution levels should not exceed an average of 25 micrograms per cubic meter of fine particulate matter.
