Are you looking for something close to Colorado Springs, or is anywhere in the state fair game?
I would think that the focus would be on good views, small obstacles, and no shelf roads?
For truly easy runs I would vote for a pass road - something like Shrine Pass, Weston Pass, or Cottonwood pass. These are borderline Subaru-grade, but would peak some interest for off-highway travel.
I like Kingston Peak west of Boulder for something that is a bit harder than a dirt road, has great views, but does not present any serious challenges. Georgia Pass is another good choice, crossing over between Breckenridge (summit county) and Jefferson (Park county).
