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.
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.
