The women's 20 kilometres race walk at the 2015 World Championships in Athletics was held at the Beijing National Stadium on 28 August.

In fact the entire Russian team did not compete here amid the drug scandal surrounding their coach Viktor Chegin.

That lasted about 4 km, from that point on the two walkers were out on their own almost tied by a string, swapping the lead occasionally though Lu was setting the pace the majority of the time.

The chase pack was Lyudmyla Olyanovska, Elisa Rigaudo, Eleonora Giorgi and Érica de Sena.

With the domestic crowd going crazy, Lu crossed the finish line virtually in Liu's shadow, the separation of 0.26 seconds giving the closest finish for a race walk in World Athletics Championships history.
