Qualification to Apply
As a requisite to apply, applicants must have completed a 50 mile race in under 13 hours between the dates of January 1, 2021 to March 15, 2023. Applicants who have completed a 100K or a 100 mile within the time limits of that race within that same time frame are also qualified to enter. You can sign up for the race without your qualifier as long as you get your qualifier by March 15, 2023. However, if a lottery is necessary, preference will be given to those runners who already have their qualifier, and those pending qualification will be placed on the waitlist. Should a spot open, they will be granted entry, pending the qualifier. Please also be aware that if you fail to qualify, your entry will be subject to our refund policy, so please review it carefully.
Applicants are also required to perform 6 hours of trail maintenance as a volunteer or 6 hours of volunteer service at another ultra or other community service from between June 1, 2022 to May 15, 2023.

All finishing Solo runners will receive special awards to include a unique belt buckle. Solo runners will have to rely on their drop bags and the aid stations for all support. Solo runners are allowed to run with other registered runners but must rely only on themselves (drop bags) and aid station volunteers throughout the entire race.
