Optimize Your Pre-Race Nutrition

Proper nutrition is just as critical as the training itself when it comes to having a successful race, regardless of the distance or discipline. While many endurance athletes focus heavily on their in-race fueling strategy, the days and hours leading up to the event are equally important to set you up for your best possible performance.

In the 1-3 days before the race, the key is to focus on carb-loading. This means eating plenty of nutrient-dense carbohydrates like pasta, rice, potatoes, and breads, while limiting high-fat and high-fiber foods that could cause digestive issues on race day. The goal is to maximize your muscle and liver glycogen stores heading into the event.

As a general guideline, you'll want to aim for 6-10 grams of carbs per kilogram of body weight per day in the 1-2 days before the race. So for a 150-pound athlete, that equates to 400-700 grams of carbs per day. This may seem like a lot, but it's necessary to fully saturate your glycogen stores.

A good plan of attack is to have a large carb-rich meal 2 nights before the race, and then focus on a big breakfast of pancakes, waffles, oatmeal, or other carb-dense foods the morning before the competition. Throughout these days, supplement with snacks like pretzels, sports drinks, granola bars, and energy gels or chews to keep your glycogen levels topped up.

For example, my pre-race fueling plan for an Ironman triathlon looked like this:

2 days prior:

1 veggie wrap
1 pear
Small chicken breast
A handful of cashews
Bagel Sandwich with Turkey
50g sports drink
1 cup Greek yogurt
A few crackers
1 sourdough bun with turkey and pesto
Handful of rice crackers
2 pieces homemade banana bread
3 oz pretzels
3 oz rice crackers
1 salmon packet
1 apple
1 orange

The day before the race:

Bagel with honey and butter
1.5 cups almond milk
2 servings low-fat Nutrigrain waffles
2 eggs
3 tbsp maple syrup
1 gluten-free waffle
50g sports drink
40 rice crackers
3 oz pretzels
Dinner (4pm): 1 cup rice, small chicken breast, 1 cup steamed broccoli

This front-loaded approach ensures my glycogen stores are fully stocked heading into the Ironman. I avoid large portions of high-fat or high-fiber foods that could cause GI distress during the event.

On race morning, the focus shifts to a simple, carb-rich meal consumed 3-4 hours before the start:

Applesauce
Scoop of whey protein
1 full sports drink (1L) with 1500mg Sodium
1/2 bagel
1 banana
1 granola bar

Sipping on a sports drink in the hours leading up to the start also helps ensure I'm well hydrated.

The key for pre-race fueling is to practice this nutrition plan in training so your body is accustomed to processing all those carbs. This will help prevent any unwanted surprises on race day.

Hydration: The Forgotten Piece of the Pre-Race Puzzle

While carb-loading gets a lot of attention in the days before a big endurance event, proper hydration is just as critical to ensure you're firing on all cylinders come race day. Failing to stay well-hydrated in the 2-3 days prior can leave you feeling sluggish, fatigued, and more prone to cramping during the competition.

The general recommendation is to drink 0.5-1 ounces of fluid per pound of body weight per day in the 48-72 hours before the race. So for a 150-pound athlete, that equates to 75-150 ounces (roughly 2-4 liters) of fluid intake each day. Focus on drinking water, electrolyte-rich sports drinks, and herbal teas to ensure you're adequately hydrated.

In addition to drinking plenty of fluids, you'll also want to pay attention to your urine color. If it's a pale, light yellow, that's a good sign you're well-hydrated. If it's a dark, concentrated yellow, it's time to up your fluid intake. Maintaining proper hydration in the days leading up to the event will help you feel energized, minimize your risk of cramping, and optimize your overall performance.

Balancing Carb-Loading with Your Regular Eating Routine

While the goal of carb-loading in the days before a big event is to maximize your glycogen stores, it's important not to completely abandon your normal eating habits. Sticking to your regular meal and snack schedule as much as possible will help prevent gastrointestinal issues and keep your energy and digestion on track.

Instead of drastically increasing your portion sizes at each meal, focus on adding in extra carb-rich snacks throughout the day. This could include things like granola bars, fruit, crackers, pretzels, or energy chews. Spreading out your carb intake in this way will be easier for your body to process compared to trying to cram it all into a few large meals.

It's also a good idea to continue eating your normal breakfast, lunch, and dinner, just with a greater emphasis on carbohydrate-rich foods. For example, you might have oatmeal with fruit for breakfast, a sandwich on whole grain bread for lunch, and a pasta dish for dinner. The key is to make gradual, sustainable changes to your diet rather than shocking your system with a dramatic shift in macronutrient ratios.

Staying hydrated and listening to your body's hunger and fullness cues will also help you find the right balance between carb-loading and your regular eating routine. With a little planning and practice, you can maximize your glycogen stores without derailing your overall nutrition in the process.

Sodium: The Forgotten Electrolyte for Pre-Race Hydration

While hydration is a critical component of pre-race preparation, it's important to remember that proper fluid intake alone is not enough. Maintaining adequate sodium levels is just as crucial to support optimal performance and prevent issues like muscle cramps and hyponatremia (low blood sodium) during endurance events.

Sodium is an essential electrolyte that plays a vital role in regulating fluid balance, nerve function, and muscle contractions. During prolonged exercise, you can lose significant amounts of sodium through sweat, which needs to be replenished to avoid electrolyte imbalances.

In the 1-2 days leading up to your race, aim to consume 800-1,200 mg of sodium per day on top of your regular dietary intake (Pretzels help!). Good sources include table salt, sports drinks, broths, and salty snacks like pretzels or crackers. Spreading your sodium intake evenly throughout the day, rather than consuming it all at once, will help your body better absorb and utilize this critical electrolyte.

On the morning of the race, be sure to have a sodium-rich breakfast, such as a bagel with cream cheese, oatmeal made with milk, or a breakfast burrito with eggs and cheese. Sipping on a sports drink containing 800-1000 mg of sodium in the 1-2 hours before the start can also help top up your levels and support proper fluid balance as you begin your event.

It's important to note that sodium needs can vary significantly between individuals based on factors like sweat rate, acclimatization, and personal physiology. Some athletes may require higher or lower amounts depending on their unique needs. Pay attention to any signs of electrolyte imbalance, such as muscle cramps, nausea, headaches, or dizziness, and adjust your pre-race sodium intake accordingly.

To determine your individual sodium requirements, consider doing some sweat testing during training to measure your sodium loss. You can also experiment with different pre-race sodium strategies and monitor how your body responds. Keep a log of your intake, hydration levels, and any performance or gastrointestinal issues to dial in the perfect pre-race fueling plan.

Remember, proper pre-race hydration and sodium balance are just as crucial as your carb-loading efforts. By taking a comprehensive approach to your nutritional preparation, you'll be setting yourself up for your best possible performance on race day.

Hydration: The Forgotten Piece of the Pre-Race Puzzle

Transitioning to In-Race Fueling

As you shift your focus from the days leading up to the race to the event itself, it's important to have a seamless transition between your pre-race fueling and your in-race nutrition strategy. The key is to continue feeding your body the carbohydrates it needs to sustain energy levels, while also introducing fluids and electrolytes to stay hydrated.

In the 1-2 hours before the start, aim for a light, easily digestible carb-focused meal or snack, such as a sports drink, energy gel, or small serving of oatmeal or a bagel. This will help top off your glycogen stores without overloading your digestive system right before the gun goes off.

Once the race begins, be sure to start consuming your planned in-race fuels right away, rather than waiting until you feel fatigue set in. This is very important to train and practice leading up.
