Unbelievable! Camille Herron Shatters 48-Hour World Record

She covered 270.5 miles in two days of running. 

She averaged 10:39 per mile pace, which included at least one 40-minute nap, according to her Instagram, so her actual moving pace was faster. 

She hit 148 miles for the first 24 hours, and 122.5 miles in the second day, as rain poured down on the runners. Only two men have ever run farther over 48 hours. She covered 1,088 laps of the track. 

Herron, 41, ran marathons in the early part of her career, recording a personal best of 2:37:14 in 2012 in Houston. She began running ultra distances in 2015 and found immediate success. She won the 2017 Comrades Marathon in South Africa, and she’s also the world record holder for 100 miles, 12 hours, and 24 hours. 

In a phone call with Runner’s World before she left for Australia, Herron said she planned to take 6- to 8-minute power naps a couple of times in the first 24 hours. “A lot of 24-hour runners don’t sleep at all for 24 hours, but I found when I did that little bit of lying down and closing my eyes and meditating, it really helped me,” she said. “I was able to extend my 24-hour record by 5 miles.

“You hear about hallucinations with ultra runners,” she continued. “When I start to feel that happening with my brain is when I lie down.” 

Earlier in her career she was sponsored by Nike and Hoka, but at the end of 2022 she left Hoka and signed a new deal with Lululemon. 

Other elite runners weighed in on the snippets of video posted to Herron’s instagram during the event. Colleen Quigley, Keira D’Amato, and Zach Bitter were among those expressing their admiration for Herron’s feat. 

Camille Herron destroyed the world record for 48 hours of running, covering 435.336 kilometers (270.5 miles) around a 400-meter track in Bruce, Australia. 

The previous record, 411.5 kilometers (255 miles), was set by Jo Zakrzewski of Great Britain in February. Herron exceeded that by 15.5 miles. She bested the previous record about 45 hours into the event—and kept running for almost another 3 hours after that.
