Opens: 4/1/24 at 6 AM PST

Qualifications:  All entrants must have run a verifiable 50k or longer trail race in 2023 or 2024.  If you don't have a qualifier prior to registering, you may list yours as "pending," add the upcoming race, and notify cuyamaca100k@gmail.com when your qualifier is completed.

The registration fee is $210.

In the event that we must cancel the race due to circumstances beyond our control (including fire, disaster, pandemic related issues, cancellation of permits) we will make every effort to refund registration fees to the extent we are able, however the amount of refunds due to emergency cancellations will depend on the timing of cancellations and current sunk costs.

In the event that you must withdraw from the race, you may request a refund of $160 before 7/01/24, and $120 before 9/01/24.  Refunds will only be processed through Venmo or Paypal; Ultrasignup does not process refunds, and we will not mail any checks.

There will be no transfers, rollovers, or discounts for next year's race.  There will be no refunds after 9/01/24.
