Race Roster provides a set of pre populated columns (i.e. Age, Bib, Division, etc.), however, your event may need a column that is specific to your event. Once the column is created it will exist and populate in the list of available columns when you upload results.

1. Go to your Timer Dashboard
2. Navigate to the left of the page and click My Custom Columns
4. Click the green Add Custom Column Type
5. Fill in the Column Type Label field
