Career

In early 2023, she achieved two Slovak women's records in 100 meters hurdle run, first at Nyíregyháza and later at Golden Spike Ostrava.[5] Wanting to capitalize on her form, she competed solely in this discipline at the 2023 European Athletics U23 Championships in Espoo.

At the 2021 Summer World University Games Forster won the 100 meters hurdle race with the time 12.72, making a new Slovak record, beating her own record of 12.82 from Golden Spike Ostrava. She also classified for the 2024 Summer Olympics by clearing the 12.77 threshold.[8] Additionally, she finished second in 100 meters race with the time 11.34.[9]
