I'm running four Epic events at Adepticon this year.

Three are one-game events on Saturday (April 2nd) . Each are basically a 3k game with an optional scenario if both players agree. If people clear it ahead of time there's also the possibility of a demo or game with a loaned army.

Epic Armageddon: Escalating Engagement 2:00-4:30 PM
Epic Armageddon: Encounter 6:00-8:30 PM
Epic Armageddon: Attack!/Defend! 9:00-11:30 PM

Sunday (April 3rd) will be the three round tournament. Due to time constraints it'll be with 2.7k lists:

Epic Armageddon Tournament 8:00-4:00 PM
