100M

*2025 Courses Coming Soon.

From the beautiful start/finish location at the historic Natural Chimneys, the course eases you in before reaching the top of Narrow Back Mtn along the scenic ridge and down buttery single-track to connect to the Wolf Ridge aid station. From there you begin your first monster climb up Wolf Ridge to Reddish Knob, over to Little Bald Knob before jumping on the iconic Wild Oak National Recreation Trail and following it over Grindstone Mtn, Lookout Mtn, Hankey Mtn and down some of the sweetest single-track to Dowells Draft. From there, the course travels south over Crawford Knob before climbing the brutal Elliott’s Knob to the course’s highest elevation, only to drop 2000’ in 2 miles down Cold Springs Trail. Take the Cold Springs forest access, returning up and over Crawford Knob, through Dowells Draft to Hankey Mtn and descend the old-school flow of Magic Moss. Continuing on the short gravel section is a welcome reprieve before the steep Horse Trough climb takes you up and over, rejoining the Wild Oak Trail and back to North River Gap. Meander your way up and over Narrow Back Mtn again via the Tillman Trail and cruise back down Lick Run to finish right in front of the towering limestone chimneys.
