Update: It took 45 days, 22 hours, and 38 minutes, but today (Sunday, September 18, 2016) ultra-runner Karl Meltzer broke the record for the fastest supported thru-hike/run of the Appalachian Trail.

Meltzer started the quest at the top of Mount Katahdin in Maine more than a month ago. He ran an average of about 48 miles per day to reach the end of the 2,190-mile trail at Springer Mountain in Georgia.
A crew followed the veteran ultrarunner in a van and aided at trail/road junctions and trailheads with support. Meltzer’s feat was documented on a microsite and sponsored by Red Bull, among other brands.
The record follows a few other high-profile FKTs (fastest known times) set on thru-hikes in the U.S., including supported and un-supported treks of the Appalachian and Pacific Crest Trails.
