Career

Justyna Święty-Ersetic competed in the 4 × 400 metres relay at the 2012 London and 2016 Rio Summer Olympics. She won the bronze medal at the 2017 World Championships in the event.

At the 2020 Tokyo Olympics she represented Poland in the 4 × 400 m mixed relay, winning gold alongside Karol Zalewski, Natalia Kaczmarek and Kajetan Duszyński. A few days later, Święty-Ersetic anchored the women's 4 × 400 m relay (Kaczmarek, Iga Baumgart-Witan and Małgorzata Hołub-Kowalik), sealing a silver for the group.^[4][5]

In March 2022, Święty-Ersetic won for the second time World Athletics Indoor Tour in her specialist distance after her 2020 victory, breaking the meeting record in Madrid.^[6]

Her personal bests in the 400 metres are 50.41 seconds outdoors (Berlin 2018), and 51.04 seconds indoors (Toruń 2022).^[7] She was part of teams which set national records for the women's and mixed 4 × 400 m relay (both Tokyo 2021), and women's indoor 4 × 400 m relay (Birmingham 2018).
