The Waitlist is now open for runners who missed the Lottery and wish to participate in this event.
If a runner withdraws from the Entrants List, a runner from the TOP of the Waitlist will be invited to fill that spot. The invite will emailed to you by UltraSignup. You will have the option to accept or decline before your credit card is charged.
The Waitlist is not viewable on UltraSignup. The Waitlist will be maintained all year round on this page. We will continue to add Waitlist runners to the race until June 1, 2025.
Waitlist invitations for the 2026 AC100 have concluded. No further invitations will be issued. The list below is retained for reference only. Previously issued invitations remain valid.
