Reinhold Metzger’s record of 5 days 7 Hours 45 minutes without being resupplied was shattered by Michael Popov. We’ve updated our JMT information page.
Speed record
The speed record for fastpacking the John Muir Trail without resupply (as of 2007) is held by Michael Popov, who completed the trail in 4 days, 5 hours, and 25 minutes. Popov carried all of his equipment and received no outside assistance.
On August 26, 2007 Sue Johnston arrived at Happy Isles trailhead in Yosemite Valley, having run from Whitney Portal in 3 days, 20 hours. Total distance 218 miles (351 km).
Popov was pushed by racing Aaron Sorensen for the record, though Aaron was forced to quit after 120mi due to foot problems.
That’s Aaron Sorensen on the left, Michael Popov on the right. They posted accounts of the “race” on Southernmostrunners.com
I don’t recommend you try to best the Popov record. Take it slow. Enjoy the JMT.
