**NOTE: This is the 2017 version and the route tends to change each year.**

In the usual fashion, the race this year, 2017, will be different and be a little like the Prescott Monster Cross…that is, it will be a loop around Flagstaff! We’ll use the Flagstaff Loop Trail augmented with some of the good singletrack on Mt. Elden and the southern flanks of the peaks. There are gas stations for those needing water or snacks at mile 21 (Conoco station right before the tunnel under highway 89…look left), mile 51 off route up hwy 180 about a ¼ mile, and at mile 57, on route 66 at the left turn onto Woody Mtn Rd.

If you are unable to navigate to a gpx file, you may very well want to stay home. There are several social trails and a few faint scratches in the dirt used for this route. Yes, you may want to wear some HAB friendly shoes for this.

large patches of snow, though not deep. Still pretty much rideable going downhill. There is a tree down in of the left hander corners.
