In addition to having strict self-discipline, Li has also helped many marathon lovers improve their long-distance results. He also established his own running club to share his invaluable experience with anyone interested in marathon.

The Chinese Athletic Association announced the latest bid data for domestic marathons on March 11. The figures shows a total of 1,581 marathons and related events were held in China last year, with an average of 4.3 games taking place every day.

Meanwhile, the cumulative number of participants in domestic marathons has reached 5.83 million. It is clear China's middle class are the mainstream for the marathon craze.

Nowadays, middle-class people pay more attention to the healthy lifestyle, and invest some of their spending for their health.

With regard to the issue, Li said running a marathon is just like making a rational, steady and long-term investment. "You may not see the effects immediately, but the longer you insist on continuing, the better result you will get."

"Quite a few people have misunderstandings about marathons, and I have to let them know the truth," Li said. "Also, some of my club members have incorrect training plans, which may do harm to their health. I have to correct those plans."

Li also added the feeling of helping others is as fantastic as winning races.

In the coming days, Li is ready for the 2019 Beverly Wuxi Marathon, hosted by Chinese Athletic Association, Sports Bureau of Jiangsu Province, and Wuxi Municipal People's Government.
