Karl "Speedgoat" Meltzer probably isn't someone you've heard of, but he's one of the greatest long-distance runners the world has ever seen.
He holds the world record for the most 100-mile trail wins with 38, but it’s his most recent (and much longer) accomplishment that has people talking about him now.
Well, that and the fact that he adopted a very unusual diet to fuel himself to the victory.
Meltzer, a 48-year-old, just set a record by running the entirety of the Appalachian Trail in 45 days, 22 hours, and 38 minutes.
(You’re probably wondering how long the Appalachian Trail is right about now, aren’t you?)
It's 2,190 miles long. It cuts through 14 states, eight national forests, and six national parks.
People who hike it generally do so over the course of seven months. He did it in a quarter of that time.
This was his third attempt at breaking the record.
Could you imagine taking three cracks at an exhausting record that you must endure for 46 days?
He was a week slow on his first attempt and ended up bowing out of his last attempt with 600 miles left.
But he continued on, determined.
“With failure comes greater success. I knew I could do it if everything fell into place, so I just wanted one more crack at it.”
He set the record on his third attempt by averaging a mind-blowing 50 miles per day.
