Blue Diamond Almonds Shamrock'n Weekend:

Please Wait...




We are pleased to announce Shamrock’n 2020 has been rescheduled for the weekend of October 31 and November 1. We hope to see all of you in the Fall, but we understand that this date may not work for everyone. You have three options for the new Fall date:

Option 1: I’m planning on participating in the Fall.
Option 2: Convert your race entry to a Virtual Entry. We will mail your 2020 Shamrock’n participant shirt(s) and medal(s) directly to you.
Option 3: Request a refund

You may log into your Race Roster dashboard here and click the “edit registration” button to select your option. We ask that you please make your selection by May 22, 2020 so that we can finalize our plans for a safe and successful Fall race weekend. If you do not choose an option, your registration will automatically move to the rescheduled October 31 or November 1 race weekend.  If you have trouble accessing your Race Roster account, call the support team at 1-855-969-5515 and they will change your address for you. To help, please mention that you are a participant for the Shamrock’n Weekend (ID 26372).

Thank you for your continued support and understanding.
