Teacher Runs 636 Miles in Six Days, Breaks World Record

Megan Eckert runs three miles to work most mornings, teaches special education all day, then coaches cross-country and track in the afternoons. Last week in Hungary, she ran 636 miles in six days without stopping.

Her students at Capital High in Santa Fe have noticed something different about their teacher. "The kids are like, 'You're that teacher that runs to work,'" Eckert shared in an interview last year.

She set the women's six-day world record at the GOMU 6-Day World Championship, covering 636.482 miles in 144 hours. No woman had ever run that far in six days, and she finished more than 50 miles ahead of every man in the race.

The achievement feels even more remarkable when you learn she ran her first race just nine years ago. She was 30 years old in December 2016, entering a half-marathon in San Antonio because the man she was dating wanted to run it.

Six months later, she won a trail marathon. The following year, she placed third among women in her first ultra race, and by 2018 she won her first 100-miler outright.

Eckert doesn't follow a training plan or work with a coach. "Everything is very loose," she told iRunFar, explaining her approach to becoming one of the world's best ultrarunners.

She excels at races with loops and time limits rather than point-to-point mountain courses. Her wins come in 12-hour races, 24-hour races, and multi-day events where mental toughness matters as much as physical strength.

This was only her third six-day race ever. She won her first one at Six Days in the Dome in Milwaukee in June 2024, then set what was the world record in France in 2025 before breaking her own mark in Hungary.

Why This Inspires

Eckert is honest with the teenagers she coaches about not being naturally fast. "I'm not a fast person, and they're running these 5Ks, and they're quick," she tells them.

But she shares something more important than speed. "If you're always comparing yourself to everybody else, you're never going to be confident enough to even chase your own goals," she told the Santa Fe New Mexican.

Once a race starts, she told her crew at one event, either she times out or gets injured. "But there's no backing out. That's not an option."

Between setting world records, she still runs to work every morning and shows up for her students every afternoon, proving that extraordinary achievement doesn't require leaving ordinary life behind.
