Grinduro CA Deferral Status

Attention riders who deferred their 2020 entry! You should have received a link to claim your 2021 spot at the email you used to register last year. The email was sent from on Tuesday, April 13. Be sure to check your junk folder for this message. If you still can't find this email with your unique confirmation link, please email


If you were registered for the 2020 Grinduro California event and deferred your registration to 2021, well let's start by saying we're excited to see you in Mt. Shasta on September 18! We have a spot saved for you.

Before registration opens to the public on Sunday, April 25, you will need to claim your deferred spot and update your personal information. You will receive an email with instructions on how to do this by Wednesday, April 14. If you do not receive this email or if you have any questions, please contact

You will need to claim your spot by 6:00pm PDT on Friday, April 23 (48 hours before registration opens to the public). If you have not claimed your spot by this time, we will assume that you do not want to keep your spot, and it will be added to the public registration allotment. At this point, no additional refunds will be offered, and your original registration fee will become a donation to Grinduro California's host organization, the Siskiyou Outdoor Recreation Alliance. If you'd like to get money back, your best option is to claim your deferred spot, and then sell it to another rider through the registration transfer process.

We hope to see you for some maxin' and relaxin' in Mt. Shasta! Full Grinduro California Details Here!Grinduro CA click through
