Some events allow participants to transfer their bib to another runner or edit their race distance. If this has been enabled, you will see the option to transfer or change your distance from your registration edit screen. To get there, visit your “Registration History” page (if you were logged in when you registered).

If you do not see the event there, then you may have registered for the event as a guest. If that’s the case, you can use this page to resend your confirmation email and use the edit link in the email:

If you do not see that option on your order edit page, you will need to contact the race directly, they have not enabled that feature for their event. You can typically contact the director via the Green “Ask A Question” button on the registration page, else, visit the event’s website for contact info.
