Features -none-


This is a 12-mile loop that will be used for the 2019 Tommyknocker 10, a ten-hour endurance race held in the Arenas Valley Area on a yearly basis.

Need to Know

The event is off for 2020.


At the designated parking area, take Woodhaul Wagon Road Trail #55 North for about half a mile. At this point turn off the doubletrack into a short section of singletrack that will take you to the Service Corrals. From the Service Corrals, enjoy a fast, flowing run down the new Watering Hole trail unitl it connects into the Fenceline Trail and follow this trail up until it reaches another gate and a set of corrals. From the corrals stay on the singletrack labelled "trail." Do not get on the Fenceline Trail yet. Take the singletrack up until you reach an intersection with the Woodhaul Wagon Road Trail #55. Turn left and then almost immediately, you'll notice singletrack that goes off to the left. Take this singletrack until it meets up with the Arenas Valley: Fence Line Trail.

Head back up Arenas Valley: Fence Line Trail until it meets up with Sawmill Wagon Road Trail #243. Climb Sawmill Wagon Road Trail #243 until you reach the Big Tree Trail #755 intersection and take Big Tree Trail #755 to the Cornell Ranch Trail #758. Follow Cornell Ranch Trail #758 back down (enjoy the nice downhill bomber run) to Woodhaul Wagon Road Trail #55. Follow this trail south until you reach a singletrack segment just below Barrel Spring. Watch your head at the beginning of the trail if you are tall as you'll pass under a metal pipe. Follow this trail back to the parking area. The trail will come very close and parallel Woodhaul Wagon Road Trail #55 at times, but stay on the singletrack. Enjoy the race, I hope to see you there!
