Chinese ultra runner Bai Bin, 48, will run from the South Pole to North Pole, covering a distance of about 24,000 kilometers in around 300 days.

Bai, a native of Guizhou Province, told a press conference here on Friday that he has 17 years' experience of ultra running and this challenge is the most important one in his life.

According to the plan, Bai will leave Beijing on Feb. 25 for China's Changcheng (Great Wall) Station in Antarctica. He will start running on March 2, crossing 65 cities of 13 countries - Chile, Argentina, Peru, Ecuador, Columbia, Panama, Costa Rica, Nicaragua, Honduras, Guatemala, Mexico, the United States, and Canada.

Bai, who won a string of ultra run competitions, made a history in 2011 when he ran more than 10,000 kilometers across six countries and regions in 150 days.

"I run 70-80 kilometers in daily training, and I am confident of making it this time," Bai told Xinhua.

"I hope more people will love this sport," he added.

He also revealed that reports of kinetics and psychology will be made based on his expedition to provide real data for the research in running and human beings' endurance.
