Fat Ass is the name used in North America for an informal, low-key style of long-distance run where organisation, entry formalities and on-course extras are deliberately kept to a minimum. The West Seattle Beach Run follows that tradition, so expect a simple, runner-driven day rather than a large commercial race. If you are unsure what a particular edition will provide, ask the organiser before you travel.

Yes. The 2027 edition is the sixth running. Results are on record for 2023, 2024, 2025 and 2026, each over 50km, with 15 finishers across those years, 10 men and 5 women.
Winning times in recent years have sat between roughly 4 hours 30 minutes and 5 hours 35 minutes for the men, and between roughly 5 hours 45 minutes and 6 hours for the women. The field is small, so times vary a good deal from year to year.
No. The event is recorded as not ranking eligible and carries no IAU label, so it does not count towards the international ranking lists or championship qualification.
