Register Online
Register by Mail
We prefer to have participants register online because it requires less work for our busy volunteers and is gentler on the environment, but we understand that some participants would prefer to mail-in their registration and entry fee. Download and complete the registration form. Make check payable to Big Sur River Run, and mail to: P.O. Box 201, Big Sur, CA 93920.
Race day registration opens at 8:00 a.m. and closes at 9:00 a.m.
As a 501(c)3 non-profit organization, the Big Sur River Run donates the proceeds from its running events to local, non-profit organizations. Learn more about our grant recipients.
Thank you for your support and we look forward to seeing you on race day!
