The Hellbender 100 is limited to 180 participants due to permitting constraints. In an effort to promote inclusion, and equality, registration will open on November 15th, 2022 with three registration pages: one for men, one for women, and one for non-binary runners. Initially, one third of all available spots (60) will be allocated to female, one third of all available spots (60) will be allocated to male, and one third of available spots (60) will be allocated to non-binary registrants.

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 your designated category has filled prior to December 15th, please join the waitlist.

On December 15th, 2022 any remaining spots within the men’s, women’s, and non-binary registration categories will open up to all runners. If, by December 15th, there is already a waitlist, additional spots will be selected from the waitlist.

If, after December 15th, all 180 spaces are completely filled, please add yourself to the waitlist. As spots open up, the Hellbender 100 team will select runners from the waitlist and they will be notified.


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 a 100-mile event with 14,000' of vertical gain between May 12, 2021 and April 12. 2023. These need not be a formal race. You can have completed a route with the aforementioned requirements in a non-competitive event, FKT, or adventure run. Be prepared to submit a proof if you are submitting the latter as your qualifier (a Strava link for example). Questions please contact
