You are able to copy age groups in RaceDay Scoring in two ways - from one Event to another, or from one Gender to another. Either way you'll need to go to the Age Group Setup page, select the Event that your changes will be applied to, then click Copy.

Copy Age Groups from one Gender to another within an Event
If you have set up all of the Male Age Groups, and have the exact same Age Groups to be set up for Females, you can quickly use this function to copy the Male setup to Females in the Event you are working with.
