Snacks are the MVPs for tournaments. Given that hundreds of people often show up to Callings , you can expect to play 7+ rounds at these events. The day will go long, and, while you can probably argue about personal rituals like being focused during a fast, hunger will still sneak up on you. You don’t want to be hungry when you’re playing your “win and in” for the Top 8. Eat, but be strategic. Convention centers will have food stands with a lot of greasy foods like burgers, hot dogs, pretzels, and all that other good stuff. These foods are terrible for keeping your energy levels and focus up. I recommend packing nuts (like almonds), granola bars, and water or Gatorade to stay hydrated. You’ll be doing a lot of walking in between rounds. Take care of your body, and it will certainly reward you throughout the tournament.
