Pre event Nutrition

@MI-XC so the challenge I have is the event starts at 0630am, I could rise at 0230 eat and go back to sleep. wake at 0500 travel to the event start and snack again (eg Gel) at the start line. The event is expected to take a min of 5 hrs so I am nervous to NOT eat a real meal before the start.
In the past, I’d just rise and at as late as I can before having to get to the event. But I am wanting to do things hopefully for the better.
thanks for the advice…
