The women's 20 kilometres walk at the 2016 Summer Olympics in Rio de Janeiro, Brazil, was held on 19 August on a route along Pontal.

Within the next kilometer, the pack was down to seven, González, two Italians; Antonella Palmisano and Eleonora Giorgi, Brazilian favorite Érica de Sena, and the two Chinese using the pace; Lu and Liu.

Before the end of the penultimate lap, Palmisano fell off the back, leaving the three Chinese vs González.

Down the final straight, Liu edged closer to González, then after getting a shoulder ahead, quickly expanded the lead.

With six officials watching over the last 100 metres, Liu did not pick up any calls and crossed the finish line first, two seconds up on González, seven on Lu.
