Sorry if this has been addressed elsewhere, but isn't the 100-mile wilderness well under 100 miles? Or do I have the course wrong? Does it end atop Khatadin?
Route: Hundred Mile Wilderness (ME)
https://en.wikipedia.org/wiki/Hundred-Mile_Wilderness: 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, 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.
I wouldn't trust google maps to show the correct distance for a footpath. Look at the FKT reports. Rob Erskine's GPS track shows 95 miles. And, no, it does not go to Katahdin.
