In 2017 she broke the women's 24-hour world record twice within twelve weeks — running 256.246 km in April before setting the definitive mark of 259.991 km at the IAU 24-Hour World Championships in Belfast, where she took the gold medal. She set the women's 48-hour world record at the UltraPark Weekend in Pabianice, Poland in 2022 (403.32 km), then reclaimed and surpassed it in 2025 with 436.371 km, breaking Camille Herron's interim record of 435.336 km by just over a kilometre.
