After taking advice from an instructor, he had a plan to make his dream come true. In 2010, he finished his first certified marathon in Shanghai and took second place.

The victory encouraged Li to train harder and learn more about the sport. Marathon was still in its infancy in China, so Li could only find information by surfing the internet.

"From reading news on the internet, I knew the marathon is one of the most popular sports in foreign countries," he said. "It is more than a game to many enthusiasts, but a lifestyle of their own."

In 2013, Li retired from the team due to physical injuries. After taking a yearlong break, he made up his mind to return to the professional path.
