Megan Eckert Sets Pending Six-Day World Record With 636-Mile Run

Megan Eckert completed 636.482 miles in six days to win the Global Organization of Multi-Day Ultramarathoners Six-Day World Championship in Balatonfured, Hungary, on Wednesday. The Guardian reported that the 40-year-old New Mexico middle school mathematics teacher finished first overall while surpassing both the women's world record and the American men's record.

Watch the highlights:

Eckert entered the championship targeting both marks. Norwegian runner Simen Holvik finished second overall with 584.631 miles, leaving Eckert with a winning margin of more than 51 miles. Her total exceeded the 603.155-mile women's world record she established at the same championship in France last year.

The previous American men's record belonged to Joe Fejes, who ran 606.243 miles in 2015. Eckert cleared that standard by more than 30 miles. She also became the first woman to pass 1,000 kilometers, equivalent to roughly 621 miles, reaching that distance after 139 hours, 55 minutes and 46 seconds.

The six-day format placed the runners on a flat, paved circuit measuring 0.5581 miles. Eckert completed 1,140 loops during the 144-hour event and averaged 4.420 miles per hour across the full period. That calculation includes time used for sleeping, eating and other necessary stops rather than only the time she was actively running.

According to the Guardian, citing race coverage from I Run Far, Eckert moved ahead of the pace required to beat the American record about 30 hours into the event and extended that advantage. She reached 550 miles after 123 hours while managing her recovery with two-hour sleep periods and shorter 15-minute naps.

The new distances are not yet official. The Guardian said the results remain pending ratification by the International Association of Ultrarunning. If approved, Eckert will hold the women's six-day world record for the second consecutive year as well as the American overall record. Her total finished about 14 miles below the overall world record of 650.919 miles, set by Russia's Ivan Zaborski in France last year.
