Nguyễn Thị Oanh

At the Southeast Asian level, Nguyễn's first medal was a silver in the 3000 metres steeplechase at the 2013 SEA Games in Myanmar.[3] The following year, she won gold in the same event at the Asian Junior Athletics Championships, but due to illness, she had to take a break from running before resuming at the 2017 SEA Games in Kuala Lumpur.[3] There, she won a pair of gold medals in the 1500 metres and 5000 metres; she repeated this feat at the 2019 SEA Games in the Philippines, and also added a gold in the 3000 metres steeplechase.[3] At the 2021 SEA Games in Hanoi, she defended all three titles,[4] and did so again at the 2023 SEA Games in Phnom Penh, while also adding a gold in the 10,000 metres.[5] Notably, in Phnom Penh, due to a last-minute change in the schedule, the 1500 metres and 3000 metres steeplechase were held just 20 minutes apart.[6] With her wins in the 2023 edition, Nguyễn became the first Vietnamese to win four individual gold medals in a single SEA Games.[7]

At the Asian level, Nguyễn was a bronze medallist in the 3000 metres steeplechase at the 2018 Asian Games and 1500 metres and 3000 metres at the 2018 Asian Indoor Athletics Championships.{[1] At the 2023 Asian Indoor Athletics Championships, she won gold in the 1500 metres and came in fifth in the 3000 metres.[8]
