All entrants from the 2018 Monterey Bay Half Marathon who chose to defer to 2020 will be given the option to switch their deferral to 2021 or 2022. Those entrants should expect to receive additional direct communication from race organizers regarding registering their choice option. If you do not hear from us, please send an email to

Per the marathon running industry policy, all entry fees are non-refundable and non-transferable to a different year. This policy applies to all entrants and is in effect whether you are injured, have an unexpected family/business emergency, have a medical emergency, etc. If the course has to be changed or the race cancelled due to an act of nature, or the event time changed due to circumstances beyond our control, there are no refunds or rollovers. You may not sell or give your bib to another person without going through the transfer process. There are NO exceptions.

You do have the option to purchase opt-in registration protection at the time of registration.

Your 2020 entry fee IS NOT TRANSFERABLE to 2021. You do not need to inform us of your cancellation. If you do cancel, you may take the amount of your entry fee as a charitable donation on your income tax return. The Big Sur Marathon Foundation is a 501(c)(3) non-profit organization.


We have switched our registration company to haku and information about registration protection will be coming soon.


While it may seem like no big deal to run without registering (a bandit) or give or sell your race bib to another person, it does present serious issues to both the race organizers and the participant field. Race results and finisher’s awards can be impacted and medical staff might not be able to identify a participant in need of treatment on the course. It is imperative that the person wearing the bib and taking part in the race is the same person that is in our registrant database.

If a person is caught wearing a bib that is registered to someone else, both parties will be banned from participating in all Big Sur events for a period of one year. The person wearing the bib will also be disqualified from any official results.
