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).
The duathlon from Blacksburg has been called the "Blacksburg Brunch", described by Kristoffer von Ow as follows:
"This tour consists of biking, hiking and trail running. The start/finish line is in the heart of Blacksburg downtown, which we chose to be the door to "The Cellar" downstairs! From there you bike essentially to Dragons Tooth trailhead via Catawba Rd.. Once at the trailhead you embark upon the hiking/trail running portion of the tour, the "Catawba Run-around", which is essentially the triple crown but created into a loop via the North Mountain Trail which connects back to the Dragons Tooth trailhead. Dragons Tooth is the only outback portion of the the entire run-around, and we chose to go in the direction of Dragons Tooth and Macafees rather than starting on the North Mountain Portion. Once you complete the Run-around you get back on your bikes and return via the same way, Catawba Rd., and rejoice at the finish line! Oh and don't forget to grab a beer at the Cellar! In total the tour amounts to around 48 miles of biking, 35 miles of hiking/trail running, and around 9400' of vert."
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.
