Team Ukraine is the favourite to take the gold medal in the mixed relay event at the Beijing 2022 Paralympic Winter Games. They are the defending Paralympic champions, as well as world champions from Lillehammer 2021 in January.
Oleksandra Kononova will be leading her teammates on the road to a new Paralympic glory alongside Taras Rad, Iryna Bui and Pavlo Bal. Kononova already picked a Para cross-country skiing gold in the women's middle-distance standing race.
Canada finished second four years ago with Germany in third. Mark Arendz, Emily Young and Natalie Wilkie will be part of the Canadian quartet again alongside Colin Cameron.
The Germans do not have any athlete from PyeongChang 2018 with Anja Wicker, Leonie Maria Walter, Marco Maier and Nico Messinger. USA's star Oksana Masters will be in search of her final medal in China.
Hosts China will be in search of a final medal in Para cross-country skiing facing strong opposition from defending champions France, led by Benjamin Daviet.
While the French team opted for two athletes taking two races each - with Anthony Chalencon alongside Daviet -, others like Norway will compete with a mixed team. Women's sprint and middle-distance standing world champion Vilde Nilsen is included in the quartet that took silver in PyeongChang.
Canada finished with the bronze medal at PyeongChang 2018 and will be in search of gold to mark Paralympic legend Brian McKeever's farewell to the Games.
The Para cross-country skier will be targeting his 17th gold medal to become the most-decorated winter Paralympian of all times.
