Description  The Hundred-Mile Wilderness is the section of the Appalachian Trail running between Abol Bridge just south of Baxter State Park and Monson in the state of Maine. It is generally considered the wildest section of the Appalachian Trail,[1] and one of the most challenging to navigate and traverse. This section of the A.T. is crossed by several logging roads and is maintained by the Maine Appalachian Trail Club. It consists of a small corridor of protected wilderness surrounded by large tracts of public and private land controlled by paper companies. An increasing amount of the adjoining lands are being protected by groups like the Appalachian Mountain Club and the Nature Conservancy.

Hi Folks,


I will be returning to the Hundred Mile Wilderness in mid August or early September of 2022 to attempt a sub-24 hour NOBO time. I have not decided if it will be supported or unsupported yet. I will reply to this thread with more details a couple months ahead of time. 




I'm planning to run a SoBo Unsupported Hundred Mile Wilderness on the weekend of August 13. I haven't been on the trail there yet, so I'm filled with hubris and trepidation, but I suppose all of that will be tested on the mud, roots, and rocks of Maine soon. Perhaps I'll run into Finn out there. Tracker link and more specific start time to follow.

Hey folks,


In 2020, I set a self-supported (intended to be unsupported but received medical aid from a passing hiker about 20 miles in) FKT of 29 hours and change on this route.

The intent was to return in 2022 to lower the time unsupported, but plans fell through (went to Chamonix for UTMB instead).

I am writing to confirm that I will be returning in the summer of 2023 to attempt an unsupported fastest known time of the Hundred Mile Wilderness.

Sub 24 hours is absolutely possible. That is what I'm aiming for - I will try my best to take it under that time.

Regardless, of whether I get it or not, the overarching purpose is to keep the spirit alive and hopefully inspire other athletes to consider a similar attempt and performance breakthrough.
