Set age requirements
If you wish to verify that a registrant is a certain age, you can do so by editing the Date of Birth field.
Step 1: Edit your campaign and click to the Layout tab
Step 2: Scroll down and edit the Date of Birth field
Step 3: Click Show advanced options
Step 4: Here is where you can set a specific age range. By clicking the Today dropdown you can have it set to be as of the day they register, or you can set it as of a future date such as race day.
If someone enters a birthdate that is outside of the desired age range, it will give an error like below.
