About this Event

This trail event starts and finishes at Classic Elite Soccer Complex and follows the unpaved trails of McAllister Park.  The actual start is on top of the dam south of the police station for those who know the trails.  It is about 1/4 mile from packet pickup and the finish at the Classic Elite soccer fields.  The finish is inside of the soccer complex.  The course runs through heavily wooded dirt trails in the dark. The 5K and 10K run completely different routes except for the last 1/2 mile where they join together. A flashlight or headlamp is required and extremely necessary. The trails can be very rocky with tree roots in places, as well as low branches so paying attention is critical. There are many opportunities to fall. This is not a trail run for beginners. It is up to you to provide your own lighting so you do not take a spill or run into a branch. Trails are marked with signage and glow sticks in the trees. Glow sticks guide you along the trail but do not by any stretch illuminate the ground, so make sure you have a good headlamp and/or flashlight. All runners will receive a tech shirt and post race beer (for those of age).  This is a fun run.  NO AWARDS will be given but overall results will be posted at the event and online.

10K and 5K Courses

Both 5 & 10k distance starts and finish at Classics Elite Soccer Academy Fields on Starcrest. At 8:50 p.m., 10k runners will be led from the soccer fields into the woods to the starting line for a 9 p.m. start. At approximately 9:05 a.m., 5k runners will be led from the soccer fields into the woods to the starting line. The 5k will take a hard left at approx .75 mi after the start and run a separate course from the 10K.  The 5k will have 1 water stop on the course and one at the finish.  The 10k will have 2 water stops on the course and one at the finish.
