This ride is horrible, the climb up Ptarmigan Road is just plain stupid and not worth the descent. This route is here for reference, but NOT recommended as a "good" route.
High altitude all day epic that includes Section 8 of the Colorado Trail but loops you back to town with a descent down Wilder Gulch.
