Hellbender 100
The Hellbender 100 is a 100-mile trail race. The 2026 edition will use an alternative course, combining elements of the 2025 route with the original course, due to trail conditions. The route passes through the Black Mountains and includes the summit of Mount Mitchell, the highest peak east of the Mississippi River.
The event is known for significant elevation change, estimated at around 48,000 feet of climbing and descending. It takes place in the mountains of Western North Carolina. The event is organized by Run828, a nonprofit foundation. A portion of the proceeds supports local nonprofits promoting healthy, outdoor activities.
The race is a qualifier for the Hardrock 100 and Western States 100. Registration is open to male, female, and non-binary runners. A qualification standard is required: completion of a 100k with 10,000 feet of vertical gain, any 100-mile race, or the Mount Mitchell Heartbreaker 50 miler between May 2024 and May 2026.
The race has a 40-hour time limit with enforced cutoffs at aid stations. All runners and pacers must carry mandatory safety gear at all times, including lights, a weatherproof jacket, an emergency bivy, insulating layers, and a hydration carrier. The event is cupless, providing a reusable cup.
Participants receive a swag bag with a t-shirt, a finisher's buckle, a sub-24-hour award, a pre-race meal, and access to stocked aid stations and finish line food. Entrants must also complete 8 hours of volunteer work related to trails or running between May 2025 and May 2026. Visit the organization's website for the most recent information.
