Run after dark on winding singletrack with short, punchy climbs and drops—ideal for first-time night racers and seasoned trail runners alike. Courses stay within the park’s competitive track system, with cool December temps and smooth, runnable footing. Start times are 5:00 PM (25K), 5:15 PM (10-mile), and 5:30 PM (5-mile), and the event pairs with the daytime McDowell Mountain Frenzy for a fun “double-down” challenge for those who race both.
