There are some arrows up from several races, but the ribbons are all down. Generally, the arrows make good guidelines.
If you find yourself needing a reference, use MTBProject and follow the "Rocky Hill Ranch Loop" (a recommended route in MTBProject).
The new sections still need some work before they are open for riders. Several bridges need to be built.
You should have plenty to enjoy.
I'll be out there tomorrow as well, doing some mapping and noting section mileages, so a slow plod about the place. I'll be on a white Specialized Levo with a green full face helmet. Say hi if you spot me out there.
