FAQ
Do previous AC100 finishes help get into the 2026 race?
Yes — previous AC100 finishes are one of the lottery boosts that can improve your selection odds.
Do I need a 50-mile qualifier to enter the lottery or waitlist?
No — you do not need a 50-mile+ qualifier to register for the Lottery or Waitlist. You can submit your qualifier during registration or later by emailing proof of a 50-mile+ race with public results between Jan 1, 2025 and Sep 3, 2026.
What are the refund timelines and policies?
50% refund available through May 1, 2026; 25% refund available through September 1, 2026. After 5 months refunds may be issued by mailed check. No deferrals or rollovers; in the event of cancellation or significant course changes adjusted policies may apply.
Can I defer or transfer my entry?
No — entries are not transferable to another person or to the next year. Entries are only valid for the year you enter; exceptions apply only if the race is canceled.
