Updating your registration allows you to change certain details about your registration, such as your leaderboard name, email address, custom field answers, or hashtags.
If you are already logged in and at the landing page of the competition, you can also press the "Registration" button. Since you are already registered, this will bring you to your registration receipt.
Once you are at your registration receipt page:
Select the “Edit Details” button in the top right corner of your registration receipt.
You should now be able to change certain details of your registration, such as leaderboard name, submitted email address, or t-shirt size if applicable.
Once you have made your changes, click the “Update Registration” button. You should now have an updated receipt on your registration page and as a notification sent to your email address.
If you do not see the "Edit Details" button after arriving at your registration receipt page, it means the competition is not allowing registration updates. You will have to reach out directly to the organizer of the event and see if they will make the change for you.
