As the number of marathons in the country continues to increase, officials have also seen the significance of rolling out better race safety measures, according to a Global Times report.
The news of five runners who died in 2015 alone has worried the government as well as Chinese amateur athletes who demand for effective steps to prevent such tragedies in upcoming races.
"Most victims are marathon amateurs. The lack of professional knowledge and awareness of their health conditions is one of the factors that caused such tragedies," an expert surnamed Chen told the Global Times.
A Chinese Athletic Association (CAA) report shows that a total of 134 marathons were held last year, a figure 10 times higher than the statistic five years ago. These marathons attracted approximately 1.5 million participants.
It was the first time that the number of marathon participants in China exceeded the 1 million mark.
As well, it was last year when China broke its record of the most number of marathons held in a single day: 11.
"The CAA lowered the standard for holding marathons as well as waiving registration fees in 2015. Such measures have partly led to the growth of marathons in 2015," Chen said.
Analysts also see the government's strengthened efforts to invest in sports as central to the boom of marathon in China.
In Oct. 2014, the State Council announced that it will focus on boosting the country's sports industry, with the aim of hitting 5 trillion yuan by the end of 2025.
"Facing such a lucrative market, many companies chose marathons as a way to gain profits, since such a massive event can attract many participants," the expert added.
Chen also highlighted the rising public awareness about health as one major reason that attracted people in joining marathons.
According to New York-based Nielsen, 80 percent of Chinese sports enthusiasts have bought running shoes. Meanwhile, 71 percent of men and 69 percent of women named running as their favorite exercise.
Nonetheless, medical experts pointed out that people should be careful in joining races.
"Marathons are not for everyone; participants should join the race based on their health condition," cardiologist Li Yongsheng said.
