If you go to MTBR.com forums, and ask on their GPS forum, a guy named natehawk will answer and tell you where to find a track. Actually, if you read the existing threads I bet you will find it. I have seen the answer lately, but since I don't use a GPS like that, I didn't pay attention.
Thanks, I didn't have a lot of luck there even with PMs so ended up finding some sections on Garmin Connect and hand drawing the rest using the PCF's published topo maps and TopoFusion. Thanks to sjanes for the help and to Rich Ridlehuber for his TNGA connector to the Pisgah Traverse which I used a bit as one of the alternates to bad pavement. I added some singletrack to replace some of the pavement redirects for bikes, at 492 miles roughly right now, couldn't say off hand the pavement/trail/fireroad mix but in the Upstate pretty heavy on the pavement (most not well traveled though and tough to say the least). Was actually MUCH easier and faster than I thought it would be.
Still working on a few alternates to get rid of bad pavement sections and the last 3 miles of hiking only trails (13 mile pavement section w/4k climbing is best alternate so far, may be easier to carry the bike partly disassembled but not sure if it's legal even to do that on the trail in question). A couple sections still need some first-hand beta done if even by car so not really polished yet.
