Event overview

Hellbender 100 is a trail ultramarathon held in Old Fort, North Carolina on May 8, 2026. The primary distance is 100 miles with pacers allowed. The course will be modified from previous years because of storm impacts and is expected to combine sections used in 2025 with parts of the original route. The route goes into the Black Mountains and includes the summit of Mt. Mitchell. The course lists approximately 48,000+ feet of elevation change. The race is presented by Run828, a nonprofit organization based in Western North Carolina.
