Basically a 34ish mile loop up and over southwest VA's three highlight peaks: Tinker Cliffs, McAfees Knob, Dragons Tooth. Somewhere around 9000ft of climbing, lots of miles on the AT. The loop also encircles the town of Catawba (NE of Blacksburg).
Thinking about giving this loop a unsupported FKT attempt in the next couple weeks. I'll shoot to beet the 6:47:46 time mentioned by prejoyful. Hopefully it'll spark some more interest in the route.
