From the start of the race, defending champion Olga Kaniskina took the lead, and only Liu Hong would go with her. The two opened up a big gap with a chase pack of a Guatemalan, the other two Russians, and the other two Chinese. By the end of 8km, the pack began to lose walkers, Mirna Ortíz and Johanna Jackson were disqualified, and Liu began to lose contact with Kaniskina, who was leading on her own. Shortly after the halfway mark, the pack was down to Elena Lashmanova and Anisya Kirdyapkina leading Xiuzhi Lu and Qieyang Shijie. An hour into the race Lu began to lose contact, allowing Lashmanova, Kirdyapkina and Qieyang to chase and pass Liu. By 14km Kaniskina had a 33-second lead. Almost unnoticeably, the gap between Kaniskina and the chasers had come down to 24 seconds at 16km, with Kirdyapkina and then Liu struggling to stay with the group. After another 2km lap at 18km, the gap was down to 17 seconds, still seemingly insurmountable with just one lap to go. With Kaniskina looking strong, the gap kept falling. Kaniskina started to show the strain, and as the pass became inevitable, she began the most pronounced arm swing trying to find a last bit of speed, but it wasn't enough. Less than 200 metres from the finish, Lashmanova went by Kaniskina and on to the gold carpet. Lashmanova finished with a 1:25:02 world record. A broken Kaniskina finished 7 seconds back, just a second slower than the previous world record. Qieyang happily finished another 7 seconds later for bronze. After the finish, Kaniskina was barely able to walk, while a fresh Lashmanova celebrated her victory.[3][failed verification]
Later, both the original top two athletes, Lashmanova and Kaniskina, and the original fifth place holder, who was also Russian, were disqualified for doping violations, and their results were annulled. After the medal reallocation, the Chinese gained a podium sweep, with the gold medal for Shenjie Qieyang, silver for Liu Hong, and bronze for Lü Xiuzhi.[4] The medal reallocation ceremony was held at the Hangzhou Olympic Sports Centre Stadium on 4 October 2023 after all the events of the Asian Games ended on that day.
