Ultrarunner sets world record, completes 64 marathons in 64 days

Alyssa Amos Clark has run 64 marathons in 64 days and counting

Alyssa Amos Clark is an ultrarunner originally from Bennington, Vt., who ran 64 marathons in 64 days as of Tuesday. She has moved around a lot, and she recently returned to the U.S. from just outside of Naples, Italy, where she and her husband had been living for the past two years. As an ultrarunner under a strict Italian quarantine, Clark came up with the idea of running a marathon on her treadmill everyday until she could run outside again. She enjoyed the ride so much that she has stuck with it well beyond the isolation period.

“In Italy we were under a very strict lockdown. We couldn’t run or walk outside without our papers with us.” She came up with the idea on March 29 and started running March 31. Until the beginning of May, every run was done on a treadmill.

Currently residing in Panama City Beach, Florida, Clark is hoping to complete 75 marathons in 75 days, well beyond the women’s world record which was previously set at 60 marathons in 60 days (the men’s record is unofficially 607, but Clark isn’t ready to commit to overtaking that mark). While Clark may continue beyond 75, she says the cumulative fatigue is building up.

“This started out being really fun, and it’s getting less fun now,” she jokes.

After she finishes her marathon streak, she’ll start training for the Moab 240, which is set to take place this October in Utah.

“I’m really looking forward to that right now,” she says. “I want to make sure I’m healthy and fit so I can have a good build.”

She’s averaging around four hours per marathon right now, but sometimes it’s a little quicker if she feels good and a little longer if the weather isn’t great. While this isn’t exactly trail running, Clark says she feels like the mental fortitude she’s gained from this experience will be invaluable when she can race on the trails again.

“The mental toughness component is huge,” she says. “This will be a great jumping off point for me fitness-wise, but I’m really excited to get back on the trails again. I’m looking forward to resuming running in the mountains.”
