The Benton MacKaye Trail is a relatively new route that opened on July 16, 2005. It runs 288 miles from Springer Mountain, GA (also the southern terminous of the Appalachian Trail), to Davenport Gap on the NC/TN line, and the northern edge of the Great Smokey Mountains National Park. The trail was created by the Benton MacKaye Trail Association.

This Friday (4/23) at noon I'll be attempting a supported Benton MacKaye FKT headed southbound. I'll be using a Spot Gen3 tracker as a primary tracker. I'll also record the whole journey via my Coros watch which I will upload to Strava after the attempt. I'll be sure to take lots of pictures and videos along the way which will be uploaded to my Facebook/ Instagram page to help verify my effort.
