**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.

VERY IMPORTANT:
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.

The straight line of this trail should be marked purple as it is a road . . . Boring

If you like having to pedal downhill through a constant rock garden, zero flow, and loose chunder, this is it.

I climbed this on way to New Heart trail. I found it to be a really good grade for a sustained climb. Beautiful views along its entirety. I did not come down it but it looks like it would be a fun one coming down.

Starts at Elden Springs Rd. Wonderful winding gradual switchbacks to the top, where it intersects with Sunset Trail. Great views! In old burn areas, along with forest. Wear sunscreen! Lovely flowers and grasses.

I road it from north to south and it was really a great fun trail. Little techy spots in between. Intermediate to advanced. Most fun flag trail so far. If you don’t mind the climb and tech to get there.
