Liu Hong became the first Chinese race walker in history to have two world records on March 9, after clocking 3:59:15 to set the world record in what was only her first Women's 50km Walk.

The 31-year-old Liu, who also holds the Women's 20km world record of 1:24:38 set in La Coruña, Spain in 2015, just came back from a nearly two-year maternity leave, but has shown great form so far this year. She finished first in both of her previous 20km outings in January and February. It was only her third race of the year.

Born in Ji'an City of east China's Jiangxi Province in 1987, Liu joined the national team in 2005. She won the Women's 20km Walk at the IAAF World Championships in Beijing in 2015 and the Olympic Summer Games 2016 in Rio de Janeiro, Brazil.
