Kendall Gretsch of the United States won a thrilling biathlon battle with compatriot Oksana Masters in the women's middle-distance sitting race at Beijing 2022, while Ukraine secured two podium sweeps in the women's standing and men's vision impaired.

Gretsch was up against compatriot Masters in an anticipated clash, with the former given the favourite tag following her gold medal in Saturday's (March 5) sprint event.

Masters led for seven of the 10 kilometres but tailed off and allowed a late Gretsch surge to get the better of her.

Gretsch, who won sprint gold at Pyeongchang 2018, crossed the line after 33min 12.3 sec.

Despite being penalised for one miss at the shooting range, she beat Masters - who was flawless with the rifle - by 8.7sec.

Anja Wicker of Germany made up the podium in 35:45.3 finish to claim the third Paralympic medal of her career, following gold and silver at Sochi 2014.

Iryna Bui led a Ukrainian podium sweep in the women's standing as she posted a time of 36:43.1

Veteran Oleksandra Kononova secured an eighth Paralympic medal 12.8sec later while Liudmyla Liashenko completed the rout in 36:56.9.

It was the second podium sweep for Ukraine after Vitaliy Lukyanenko, Oleksandr Kazik and Dmytro Suiarko won gold, silver and bronze, respectively, in the men's vision impaired sprint.

There was heartbreak for China's Guo Yujie, who won gold in the sprint, as she led for 80 per cent of the race but dropped off a cliff to finish fourth.

Yet another podium sweep was in store a few hours later in the men's vision impaired as Vitaliy Lukyanenko won the eighth Paralympic gold medal of his career with a time of 34:12.7.

Anatoliy Kovalevskyi and Dmytro Suiarko then followed the 43-year-old across the line to win silver and bronze, respectively.

Iaroslav Reshetynskyi and Oleksandr Kazik then completed a remarkable race where Ukrainian athletes secured the top five positions.

Liu Mengtao won China's eighth gold medal of the Games after a commanding 30:37.7 finish in the men's sitting event at the Zhangjiakou National Biathlon Centre, adding to his bronze from the sprint.

Martin Fleig redeemed himself after a poor showing in the sprint as he clocked in after 31:23.7, which gave the German a silver medal.

Ukraine's Taras Rad was unable to live up to his billing of favourite and had to settle for bronze with a time of 31:26.9 as he suffered from four shooting penalties.

She triumphed in a thrilling battle with Oleksandra Shyshkova of Ukraine.

Shyshkova was the nailed-on favourite, especially after taking sprint gold on Saturday (March 5), but two misses at the shooting range cost her the win as she clocked in 3.7 seconds slower than the 18-year-old Walter.

The pair were lightyears ahead of the rest of the field, with China's Wang Yue claiming bronze after 42:50.3.
