Relays work differently in Athletics.app from all other events.
Only once you have created 1 or more relay teams does this event appear in the schedule. You can then also specify a start and finish time for that event.
Note: The relays are not always displayed in the visual timetable.
It is planned to improve this, however, so that relays are aligned with all other events.
