Liu, who won the Olympic distance 20km gold in Rio, clocked three hours, 59 minutes and 15 seconds for the longer race, the IAAF said in a statement, clipping more than five minutes off the previous record (4:04:36) set by compatriot Liang Rui in Taicang last year. The 31-year-old now holds the world record for both the 20km and 50km distances, having clocked 1:24:38 in La Coruna, Spain in 2015 for the shorter distance.
She also won the 20km gold at the 2011 and 2015 World Championships. (Reporting by Greg Stutchbury; Editing by Peter Rutherford)
