Registration & Requirements

The Hellbender 100 is open to male, female, and non-binary runners. Register here.

Transgender and non-binary runners are encouraged to participate! We will accept every transgender and non-binary runner’s self-declared gender category at registration and no one may challenge a runner’s self-declaration.


If registration fills by the time you enter, you will be added to the waitlist. You will not be charged for entering the waitlist. You will be charged the entry fee only if you accept an invitation from the waitlist.

You must have completed a 100k with 10,000' of vertical gain or any 100 miler between May 1, 2023 and May 1, 2025, or Mount Mitchell Heartbreaker 50 miler. These need not be a formal race. You can complete a route with the aforementioned requirements in a non-competitive event, FKT, or adventure run. Be prepared to submit proof if you are submitting the latter as your qualifier (a Strava link for example). Questions please contact

Volunteer requirement: At least 8 hours of volunteer work must be completed between 5/12/2024 and 5/1/2025. This can be trail work, volunteering, race directing at a race, or any other trail/running centered activity. Again, if you have questions, email

We are a Hardrock 100 qualifying race.
