Lots of Dirt! The main route is shown here, there is a variation shown on the detailed map and included in the kmz file. While the shortcut starts off reasonable there is a very rough single track at the end. I had to walk half a mile on my touring bike. Most hardy people on road bikes will prefer the main route; the rest will have given up before the shortcut starts! Wide tires recommended in any case. 41 miles.
