Preparing for a triathlon involves more than just intense training sessions and buying all the fancy gear. One of the most critical factors influencing your performance is your pre-race nutrition. The night before a race, especially, food plays a vital role in ensuring your energy levels and digestive system are ready to go for the big day.

I understand the challenges of race preparation because I’ve been there. Helping triathletes is my passion (and our obsession here at MOTTIV), from those attempting their first sprint triathlon to seasoned competitors taking on longer distances. With the right plan in place, you’ll feel confident, prepared, and of course, adequately fueled for success.

Pre-Race Nutrition: Getting Ready for Triathlon Success

Even though this article will focus on your pre-race dinner, remember that the 24 hours leading up to race day are equally as important. You'll want to think about your breakfast, lunch, and snacks as well during this critical fueling window.

The Importance of Nutrition in the 24 Hours Leading Up to Race Day

The day before your event is a critical time window for topping off your glycogen stores and preparing your body for sustained energy output. Your goal is to fuel your body without overloading your digestive system.

Why it matters: Eating slightly more than normal with an emphasis on carbohydrates ensures your muscles have enough glycogen to power through the event.

What to avoid: Avoid stuffing your face with unfamiliar foods or eating excessively, as it can cause gastrointestinal (GI) distress during the race.

Key Nutrients Every Triathlete Should Focus On

All of your pre-race meals, including the meal you eat the night before, should include a balance of macronutrients. You don't want to just load up on plain pasta, as popular as this option is. Make sure to throw in some high-quality fat and protein to keep your finely-tuned system running at their best.

Carbohydrates: This is the primary energy source for endurance athletes. Aim for grams of carbohydrates tailored to your body weight.

• Examples: Pasta, rice, sweet potatoes, bread, waffles

Lean protein: Supports muscle recovery and repair.

• Examples: Grilled chicken, salmon, turkey, or tofu

Fats: Provides sustained energy for longer races like an Ironman.

• Examples: Avocado, olive oil, or a small handful of nuts

Electrolytes: Sodium, potassium, and magnesium are critical for maintaining hydration and performance.

• Examples: Salted crackers, sports drinks, or electrolyte supplements

The Role of Carbohydrates in Pre-Race Meals

Carbohydrates are the star of any pre-race meal, whether it's breakfast, lunch, or dinner because they fill your muscles’ glycogen stores and prime your body to race. As you might know, they're also a quick energy source during your race, and that's why so many in-race fueling plans focus heavily on them. Here's a quick reminder on all things carbs:

Benefits of carbs:

• Quick and efficient energy
• Improved endurance during the race
• Help delay fatigue

Carbohydrate-rich meal ideas for any time of day:

• Bagel with almond butter and jam
• Pretzels or crackers with hummus
• Spaghetti with marinara sauce and a side of steamed veggies
• Rice bowl with grilled chicken and avocado
• Whole-grain bread with roasted sweet potatoes and lean turkey

Hydration Tips Before the Big Race

Staying adequately hydrated is essential in the days leading to the race. Hydration doesn’t just mean drinking water – balancing it with electrolytes is key.

• Sip water consistently throughout the day. Aim for 0.5-1 cup every hour.
• Include sports drinks with sodium and potassium to maintain electrolyte balance.
• Avoid overhydration, which can lead to a dangerous condition called hyponatremia.
• Skip alcohol the evening before the race as it dehydrates the body.

What to Eat the Night Before to Ensure Optimal Performance

Now that you understand what to focus on during the day leading up to your race, let's take a look at dinner, specifically. Remember, it's smart to taper food intake throughout the day on the day before your race. That means a larger breakfast, medium-sized lunch, snacks, and finally, a moderate yet carb-rich dinner that won't tax your digestive system or cause sleep disturbances.

Dinner Ideas for Triathletes

The evening before the race, focus on a moderately sized meal with higher-than-usual carbohydrates that your body can easily digest.

Here are some of our favorite, balanced pre-race dinner options:

• Pasta with grilled chicken and steamed broccoli: A classic, easily digestible option with plenty of carbohydrate and lean protein. Keep the broccoli portion small as to not overload on fibre.
• White rice stir-fry with lean beef and veggies: Provides a mix of quick and slow-digesting carbs. Again, don’t overdo it on the veggies.
• Baked potato with salmon and green beans: A hearty meal packed with energy and essential nutrients.
• Simple pasta with tomato sauce: Choose gnocchi, spaghetti, or any favorite shape for a classic, high-carb, low fibre dinner.
• Pizza, hold the cheese: Opt for a simple marinara that’s light on the cheese, or go for minimalist toppings overall to keep fat and fibre on the lower end of the spectrum.

Foods to Avoid the Night Before Your Triathlon

Certain foods can negatively affect your performance by causing bloating, discomfort, or GI distress. Avoid these common pitfalls, as well as anything else you know you don't tolerate well:

• Spicy foods: These can irritate your stomach and cause discomfort on race morning.
• High-fat meals: Heavy foods like steak or fried items are harder to digest and may leave you feeling sluggish.
• Excessive fiber: Foods like beans, lentils, and large salads can cause bloating.
• Alcohol: Even a single glass of wine can interfere with your hydration levels. While some amateur athletes and even pros swear by a glass of wine to calm the nerves, proceed with caution! Alcohol can also disrupt your sleep, and as we all know, that’s a precious commodity the night before a big race.

Timing Your Pre-Race Dinner

Many triathlon nutrition experts recommend eating your pre-race dinner earlier than usual to allow for adequate digestion and pave the way to better sleep. We know how tough it can be to get a good night's sleep the night before a race, with your nerves firing and your mind going a mile a minute. Don't fuel the fire with a too-large or heavy pre-race dinner.

Tips for the Traveling Triathlete

Racing overseas or away from home can introduce complications to your nutrition plan. What if you can't find your favorite pre-race dinner, or you don't have access to a kitchen? Here are a few of our tried and true tips for this scenario:

• Consider bringing your own snacks and foods that you've tried before in training and racing.
• If you're traveling and don't have access to foods that require a refrigerator, prioritize familiar, simple options. Ease of preparation is key.
• Rely on portable foods like bread, peanut butter, or pre-cooked rice.

The Morning of the Race: What to Eat for Optimal Performance

Your pre-race breakfast should provide sustained energy without overloading your stomach. Aim for a mix of carbohydrates, a small amount of lean protein, and minimal fat.

• Oatmeal with banana and honey: A quick, energy-packed meal.
• Toast with peanut butter and a fruit smoothie: Combines carbs and a touch of protein.
• Scrambled eggs with whole-grain toast: Perfect for those who prefer a savory breakfast.

Timing Your Morning Meal for Best Results

As with dinner the night before, eating at the right time on race morning ensures your pre-race meal will do its job without causing discomfort. And remember, you'll also be nervous, so don't stir the pot by adding in excess amounts of food. Here are our favorite tips for race morning meals:

• Consume breakfast 2-3 hours before your race start to allow proper digestion.
• Avoid large meals closer to your race start time to prevent feeling heavy or sluggish.
• If you need a quick boost minutes before the race, small snacks like a banana or an energy gel are effective.

Tailoring Nutrition Plans for Different Types of Athletes

No two athletes are the same, so personalizing your nutrition plan is essential. You know yourself best, so add a grain of salt to all "expert" nutrition advice (and meals!)

• Body weight: Larger athletes may need more carbohydrates to sustain energy.
• Experience: Novices might benefit from simpler, easily digested meals.
• Dietary restrictions: Work with a dietitian to find alternatives if you have allergies or preferences.

The Impact of Caffeine on Performance

Caffeine has been shown to enhance focus and performance, but it should always be used carefully. As with all other food items, don't do anything new with caffeine on race day! You could end up with problems you didn't even know existed.

Benefits:

• Caffeine increases alertness and reduces perceived effort.
• It also helps mobilize fat for energy, particularly during longer races.

Safe guidelines:

• Consume 1-3 mg of caffeine per kg of body weight about an hour before the race.
• Avoid overdoing it, as too much caffeine can cause jitters or GI distress.
