qualifications
trail work
Entrants get to do 8 hours of trail work. This trail work must be completed between August 1, 2025 and June 14, 2026 and done with an organized work party such as the PCTA, WTA, or other trail work organization.
Volunteering, crewing or pacing at a race does not qualify as trail work.
Race qualifier
If entrants have ever run an 100 mile trail run, they qualify (but still need to submit that in the race qualifier form). If not, entrants must complete an organized or self-supported (with Strava track or equivalent verification) trail 50-miler within 16 hours that has at least 6,500' of climbing and must be between January 1 and June 14 of the year in which they wish to race.
You have the option of buying out the trail work requirement by making a $150 donation which will be directly sent to one of the trail work organizations that Cascade Crest 100 supports.
Note that trail work buyouts are not refundable in the event of withdrawal from the race.
Deadline for Race Qualifications: June 14, 2026

The fine print
deferral
If you’ve had a significant and/or unexpected life event, deferrals will be considered on a case-by-case basis. Please send an email to the RD at info@cascadecrest100.com to inquire.
cancellation + Refund
Anyone dropping out by June 14 will receive a $150 refund of entry fees. After June 14, a $50 refund will be given until the waitlist closes on July 12th.
Transfers
Registrations are non-transferable, and no credits will be issued.
Race cancellation
If we have to cancel the race for any reason, if it’s more than 30 days before race day, we will offer a 50% refund of your registration (less fees). If it’s within 30 days of the race, we are unable to offer refunds but you can be an auto-entry for the following year (only).
waitlist
If a confirmed runner cancels their registration, a waitlist registrant may be invited to register and take their place.
If you are moved off the waitlist, you will have 2 days to confirm and accept the invitation before the runner in the following position on the waitlist is invited.
Please check your Ultrasignup email account! A healthy number of runners move through the waitlist each year. So be ready!
