The Edge of Appalachia nature preserve spans 20,000 acres in Southern Ohio. Like the name suggests, this region of Ohio sees a dramatic shift in landscape as the Midwest borders Appalachia. A new (as of 2019) section of the Buckeye Trail moved almost 16 miles of Ohio's Buckeye Trail that had previously been on roads onto brand new singletrack. This route is ~50k out and back on that new section of beautiful trail. Like the rest of the Buckeye Trail, it is marked with blue blazes. The start/finish point has a small parking lot with bathrooms at 3223 Waggoner Riffle Rd. The route crosses a few country roads that could be used for aid stations. The turnaround at ~15.35 miles is where the singletrack meets Sunshine Ridge Rd just off of Slate Fork Rd, 1/4 mile from "Point 28" on the West Union section of the Buckeye Trail described here: https://www.buckeyetrail.org/sections/sections.php?section=westunion. Once you meet the road, you can turn around for this route. The Buckeye Trail would continue from that point onto Sunshine Ridge Rd out of the Edge of Appalachia preserve towards Shawnee State Park and all around Ohio.
