We allow participants to edit their race pack item size after registering for an event. However, when your data has been locked for processing (ie. bib printing), you will not be able to edit your race pack item size anymore.

Login to your Spacebib account.

Under My Participation, look for the race that you want to edit.

Click on Edit Participation.

Under Participation Details, edit the Race Pack Item details to the correct details.

Once done, click Save.
