Every Surface, Any Distance: Top Ultramarathon Performances of 2025
"The highlight of the 24-hour distance in 2025 has to be Sarah Webster's (U.K.) world record at the IAU 24-Hour World Championships in France this October. She ran 278.622k (173.127 miles) to eclipse the previous record set by Japan's Miho Nakata of 270.363k (167.996 miles) in 2023 by an incredible margin of 8.259k (5.131 miles). It was a phenomenal distance, almost unthinkable a few years ago."
"On the roads and tracks, runners set several world records across events ranging from 50 kilometers to six days, including Sarah Webster's (U.K.) world record at the IAU 24-Hour World Championships, where she eclipsed the previous mark by a massive 8.259k (5.131 miles) in running 278.622k (173.127 miles). While it is harder to objectively quantify top trail-ultra performances, numerous efforts broke longstanding course records and bested super deep fields, including American Anne Flower besting the 31-year-old Leadville 100 Mile record."
2025 delivered extraordinary ultrarunning advances across roads, tracks, and trails, with multiple world records and historic course breakthroughs.
