A blame game has begun in the aftermath of the Standard Chartered Marathon, which contrasts sharply with last Sunday's peaceful and jovial mood.
Poor air quality has been cited as one of the major factors that made thousands of runners unwell, and for this the government and power companies have borne the brunt of criticism.
More than 4,800 runners received medical treatment. Twenty-two were taken to hospital and one, Tsang Kam-yin, 53, has died.
Sports experts and long-time competitors have blamed these mishaps on a lack of preparedness among many runners.
The Chinese-language Hong Kong Economic Times has also listed the marathon's 'five crimes': the failure to warn participants about poor air quality, the failure to screen competitors for physical strength; the unsuitability of a section of the route; inadequate 'must-know' information; and the lack of fitness tests for participants aged 45 or above.
The organisers have been criticised for seeking publicity by hosting an event at the expense of public health. Critics also pointed an accusing finger at the government for its lack of vigilance about the health risks and chaos.
