Competition day is finally here. You’ve trained for months and maximized your recovery, and now it's time to step up and perform. The last thing you need is your nutrition holding you back after all the hard work you’ve invested. One of the biggest factors that can make or break your performance is how you fuel your body throughout the day. So, here’s what you should know about eating for competition days.
Regardless of the specific event or setup, all competitions have basic guidelines that are a good idea to follow. These are methods that will benefit most competitors as they approach their events — just take it from our friend Adee.
Stick to familiar foods
Competition day is not the day to be trying out new foods or supplements. You want your day to be as predictable as possible and that includes your nutrition. Adrenaline and nerves will also be part of the process, so ensure that your stomach and body feel good by using foods you already know help you perform well.
Take it for a test run
Regardless of the competition, you spend countless hours practicing for it. We train and we test ourselves at every step of the way so that the day of is familiar. Practice your nutrition too. Use a test day before the competition to run through your fueling strategy and ensure that your food choices work well for you.
Nerves and adrenaline are two of the defining characteristics of a competition day versus a training day, and can easily affect your appetite. Regardless, be sure that you keep a regular eating schedule throughout the day. Also, make sure to space those meals out around your competition so that you aren’t eating too close to go time.
Consider your carbs
Carbohydrates are the most manipulated macronutrient when it comes to prepping for a competition. They are the easiest source of readily accessible energy for our bodies and we can use the characteristics of different carbs in order to maximize our energy. The main way we measure this is the glycemic index, which measures how fast the sugar from carbs is released into our bloodstream.  Carbs lower on the GI index give us slower waves of energy, which helps us stay steady for a longer time. Carbs higher on the GI index give us a quick burst of energy, which helps us fuel up and recover quickly. Although different types of carbs are useful for different circumstances, all competitors can benefit from manipulating their carb choices.

Trim the fat
Avoid placing too many fats around your competition. Although fats do give us long-burning energy, they take a long time to digest. If our bodies are focused on digesting fats instead of maximizing carbs, we’ll see less benefit from our competition fueling. Stack fats more in the morning or evening and less around competition time. 
It’s not uncommon to approach the evening of our day after a competition as an opportunity to have a “free for all.” Just remember that overindulgence could have a negative effect on your body and you want to give your body the right nutrients to recover. Enjoy your hard work, but also live to fight another day.
Some competition styles involve all-day competitions that take place in heats, such as CrossFit competitions. Other sports have tournaments where you may be playing several matches or games over the course of a few days. All of these situations involve moments of high energy followed by long breaks. The key is to recover well from previous events and fuel up for future events, so you can maintain energy throughout the whole day.
Pre-Competition: One hour before your competition begins, eat your normal pre-workout meal. Make this a mixture of moderate- and high-GI carbs. The moderate-GI carbs will help get sugar into your bloodstream slowly and the higher-GI carbs will give you the quick hit of energy you need once you go into the first session. Consider a bagel with 15–20 grams of peanut butter and honey, whole-grain toast with jelly, or sweet potatoes with some brown sugar.
Nutrient Timing: For each subsequent session after the initial one, eat a meal of high-GI carbs 30 minutes before you begin. After each session, eat a recovery meal of high-GI carbs immediately. Both meals could be things like fruit squeeze packs, pretzels, cereal, rice cakes, etc. Continue this pattern for the total number of sessions you have that day. Throughout the day consume moderate amounts of protein regularly as well. The timing of the protein isn’t as critical as long as you’re getting it in throughout the competition. Also consider if you’ll have any longer breaks for lunch, which would give you an opportunity for something more substantial. 
Events that require steady energy production throughout a long-time period are common with running, biking, swimming, skiing, and other endurance sports. You will need to have enough fuel beforehand to help you maintain energy, without it causing any detriment to your performance. In addition, you will need to take in nutrients while you are actively competing, which changes the nature of nutrient timing and food choice.
Pre-Competition: In the morning, try to eat 100–150 grams of low-fiber high-GI carbs two to three hours before your race. This could be a bagel with peanut butter and honey plus a carb sports drink. The key is to keep the sugars simple. Then, get 10–20 g of protein (this is why peanut butter is a great choice!). You want to have good energy stores for your body to use when you begin.
Intra-Race Fueling: While you’re racing, you’ll want to stay fueled, and taking in carbs during can help prevent fatigue. Shoot for about 1/4 of your body weight (lbs) in grams for each hour of training or racing past 45–90 minutes. For example, a 130-lb marathoner should ingest about 30–35 g of carbs each hour of training or racing. These carbs need to be things that are very simple sugars and easy to digest. 
Hydration: In an endurance situation, you will be losing a lot of water, but also a lot of other important nutrients in that water, such as electrolytes. Be sure to stay hydrated during the event by ingesting water as well as liquids that contain electrolytes. You can buy drinks with electrolytes and sugar in them to take care of both fueling and hydration, or you can buy electrolyte tabs to add to water.
Post-Race Recovery: Due to the large amount of energy expended during endurance sports and the inability to fully fuel during the race, you will need to focus on recovery after. Aim for 50–100 grams of carbohydrates, preferably in liquid form, immediately after the race to promote re-hydration as well as carbohydrate repletion after a race. Then try to add in approximately 5–9 g of protein with every 100 g of carbohydrates eaten after a race. 
Many competitions involve a single major event, such as a basketball game or Olympic lifting competition. In this situation, fueling for the competition is a lot more like we’d fuel for our daily workouts.
Pre-Competition: One hour before your competition begins, eat your normal pre-workout meal. Make this a mixture of moderate- and high-GI carbs. The moderate-GI carbs will help get sugar into your bloodstream slowly and the higher-GI carbs will give you the quick hit of energy you need once you go into the first session. Consider a bagel with some peanut butter and honey, some toast with jelly, or sweet potatoes with some brown sugar.
During Competition: If your event does allow you some downtime and if you will be resting at all, make sure you refuel as needed, such as at halftime in a game. You’ll want to focus on faster carb sources high on the GI index, such as fruits and rice.
Post-Competition: When you’re finished you want to be sure to help your body recover and refill its glycogen stores. Again, you’ll want to turn to faster carb sources that are simpler sugars. Also be sure to include some protein after the event to help your muscles repair and replenish.

While not all competition styles are the same for weight-class sports, they all involve manipulation of body weight before the competition day. This adds an extra layer of considerations when going into the day. Making weight could range from keeping an eye on nutrition the week before to a long period of cutting. Depending on your situation, cutting down to a weight class could be a gradual thing or might involve you arriving at the competition in a dehydrated and under-fueled state. Regardless, the key is to make sure that you recover adequately before your event.
Cutting for an event is a very individualized and personal decision, based on a variety of factors. Check out the free Weight Cutting for Athletes ebook from Team WAG. This guide will help you navigate the process and make weight without sacrificing performance.
Preparing for a competition is a long process and you never want your nutrition to be the factor that causes you to stumble. Working with a coach is a great way to make sure your nutrition is dialed in and you perform your best.
