The record so far
Stine Rex is a Danish fixed-time and road ultrarunner. Guinness World Records recognizes her 928.577 km in Aabybro in September 2025 as the women’s six-day competition record.
Her record also includes 435.564 km at the 2024 GOMU 48-Hour World Championship, which won the women’s title and went 228 metres beyond Camille Herron’s world record of the time, although the IAU never ratified it because the race had no federation permit or IAU label. In 2026 she won the 230 km TorTour de Ruhr outright in 26:38:05, then covered 1,301.591 km in the Åbybro ten-day race in August, first among women and second overall, a distance that tops DUV’s all-time women’s ten-day list as of October 2026.
DUV’s event table gives a slightly longer 930.006 km for the 2025 six-day race; the ratified Guinness figure is 928.577 km.
Guinness classes the mark as a world record, while the IAU lists six-day distances as world-best performances, and its table still shows Rex’s 928.577 km. Megan Eckert’s 1,023.948 km at the 2026 EMU 6-Day Race, which the IAU described in September 2026 as a new women’s world-best performance, is still awaiting ratification.
