Megan Eckert has become the first woman to run more than 1,000 kilometres in six days, finishing the GOMU 6-Day World Championship in Balatonfüred, Hungary, with 636.482 miles (1,024.319km). The distance broke her own women's world best and also eclipsed the overall American record, and she won the race outright by almost 84 kilometres.
Eckert passed her previous record of 970.685km (603.155 miles), set in France in 2025, after 135 hours and 38 minutes. Within roughly 30 minutes she had also overtaken the overall American six-day record of 975.653km (606.243 miles), which Joe Fejes had held since 2015. She went through the 1,000km mark at 139 hours, 55 minutes and 46 seconds, and her average speed across the full 144 hours, including every stop and sleep break, was 4.42mph (7.11km/h).
The race is run on a certified 898.2-metre asphalt loop through a campsite beside Lake Balaton, so Eckert completed 1,140 laps plus 371 metres. Simen Holvik of Norway was second overall on 940.415km, with Mario Čeliković of Croatia third on 861.373km. Tomomi Bitoh of Japan was the next woman home on 802.092km, underlining how far clear of the field Eckert finished.
Context matters for a record of this kind. Sandra Barwick's 883.631km stood as the women's mark from 1990 until Camille Herron ran 901.764km in 2024, and Stine Rex of Denmark later went to 928.577km, which the IAU still lists as the women's best. Eckert's 970.685km from 2025 remains on the IAU's pending list with data and clarifications requested, although GOMU recognises it. The men's benchmarks remain Ivan Zaborskii's 1,047.554km from 2025 and Matthieu Bonne's 1,045.519km from 2024, which leaves Eckert about 23km short of the outright best.
Eckert is a middle-school maths and special-education teacher in Santa Fe, New Mexico, and her ultra résumé is broader than the track. Last year she finished third woman and eighth overall at the Cocodona 250 in May and won the women's race at the Vermont 100 in July in 17:19:56. Her latest result moves the debate on what is physically possible in multi-day running firmly towards the men's records, and it gives the sport a clear new benchmark for women's performance beyond 1,000 kilometres.
