Finland's Satu Lipiainen Sets Women's 6-Hour World Record

Satu Lipiäinen set a new women’s 6-hour world record by running 85.712 kilometers at the 2026 Kokkola Ultra Run in Finland. The mark surpassed the previous record of 85.492 kilometers set in 2017 by Nele Alder-Baerens by 234 meters. The Kokkola Ultra Run is an IAU Bronze Label event with 6-, 12-, and 24-hour races, and the record is currently pending ratification. Lipiäinen averaged a 4:12 per kilometer pace and reported holding a 4:00 per kilometer goal pace for the first couple of hours, completing her first marathon in 2:50. She later struggled with energy and confidence, then increased effort in the final hour. The course is half gravel and half tarmac, with about one meter of elevation gain per lap, and she completed 99 laps.
