Fuelling Up: What to Eat Before a Marathon

Fuelling Up: What to Eat Before a Marathon

So, you’ve put in the miles, laced up those well-worn shoes, and now race day is just around the corner. But before you hit that starting line, there’s one last thing you need to nail down—your pre-race nutrition. What you eat in the 24 hours leading up to the marathon can make or break your performance. Let’s break down how to fuel your body right, so you can cross that finish line feeling strong.

The Day Before: Carb-Loading Done Right

The idea of carb-loading the day before a race has been around for ages, and for good reason. Carbohydrates are your body’s primary fuel source during endurance events, so you’ll want to top up those glycogen stores in your muscles. Think whole grains like brown rice, quinoa, and whole-wheat pasta paired with lean proteins like chicken, tofu, or fish. Don’t go overboard though; the goal is to eat a bit more than usual, not to stuff yourself to the brim. And remember, slow and steady wins the race, so spread those meals out throughout the day.

Hydration: Sip, Don’t Guzzle

You’ve heard it before—hydration is key. But the day before your marathon, it’s about sipping consistently rather than chugging gallons of water in one go. Along with water, consider adding an electrolyte drink to the mix, especially if you’ll be racing in hot weather. Electrolytes help maintain your fluid balance and prevent muscle cramps, giving you one less thing to worry about on race day.

The Night Before: Keep It Simple

Dinner the night before your marathon should be a balance of carbs, protein, and fats. Aim for something familiar to your stomach—this isn’t the time to experiment with spicy or exotic dishes. A plate of grilled chicken (or meat free alternative), sweet potatoes and steamed veggies will do the trick. And while dessert might be tempting, it’s best to skip the sugary treats; they can mess with your blood sugar levels and leave you feeling sluggish.

Breakfast: Rise and Shine with the Right Fuel

On race day morning, you’ll want a breakfast that’s high in carbs, moderate in protein, and low in fat. Think oatmeal with a banana, a slice of toast with peanut butter, or a bagel with honey. Try to eat about 2-3 hours before the race starts to give your body time to digest. And don’t forget the coffee if that’s part of your normal routine—just maybe not a double espresso if you’re normally a half strength drinker!

Don’t Forget the Snacks

Depending on how early your marathon kicks off, you might need a small snack closer to race time. A handful of nuts, a small granola bar, or even half a banana can keep your energy levels steady without weighing you down. The goal here is to maintain that steady stream of energy so you’re not starting the race on empty.

Mind Your Gut

It’s not just about what you eat, but how it affects your gut. Stick to foods you know won’t cause digestive issues. Avoid anything high in fiber, greasy, or overly rich. The last thing you want is an emergency bathroom stop halfway through the race.

Listen to Your Body

Lastly, remember that everyone’s body is different. What works for one runner might not work for another, so it’s important to listen to your own body. Pay attention to how different foods make you feel during your training runs, and use that knowledge to guide your pre-race nutrition choices.

Crossing the Finish Line

With the right fuel in your tank, you’re setting yourself up for success. Eating strategically in the 24 hours leading up to your marathon can help you avoid hitting the wall and keep you strong all the way to the finish line. So, get your meals planned, hydrate well, and trust in your training—you’ve got this!
