Depending on whether you are create a 1-class event or have an event that requires multiple heats, you can set-up your calendar accordingly.

On the "Coaching Schedule" tab in the menu - click "Create Single Class".

Make sure you select the Track you created for the event. Set-up the rest according to your needs for the event. Date and time for the event, set the attendance limit if you need to CAP the event, etc.

If it's an event that you don't want to count towards membership limits (punchcards or limited memberships per billing cycle), make sure to check the box "this class does not count towards membership limits". i.e. - holiday party, ladies night, charity event, etc.

If you're running multiple heats (ex. - Murph or The Open), create multiple classes for each specific heat so people can reserve for the heat they want OR you have the option to manually add members to that class when you're setting up that class.
