A ~10 mile loop in the Linville Gorge. Note there are a couple Strava segments along this route: Linville River to Old NC 105, and Pinchin>>Linville River>>Conley Cove>>Rock Jock, but the FKT route closes the loop, which adds just a few minutes to the latter Strava route. This route also covers the entire Pinchin Hiking Trail, which has its own Route page.
Grant Barnette describes the route:
Starting at Pinchin trailhead, head down the steep trail, losing 1600ft of elev. (1.1 miles) and take the Linville Gorge River trail for approx 6 miles, take a left up Conley Cove for approx 2 miles, then take a left at the Rock Jock junction. Climb all the way up to Rock Jock (very steep) to Kistler Memorial highway and take the gravel road back to Pinchin trailhead. (Less than a mile).
