Here's my best guess of a route based on their description. I'm sure some of the locals can chime in on road choices. I've only driven in the area. One loop has an elevation gain of 1,400. So you're looking at roughly 2,700 to 2,800 adding another lap and taking it back into town.

EDITED: Pulled my map. Actually map has been posted by race director in post 101. But I was pretty close.
