How to Fuel Your Marathon: Nutrition Secrets Revealed
Running 26.2 miles requires more than determination and discipline — it requires fuel. Your body depends on steady nourishment to power long training runs, support recovery, and keep your energy stable all the way to the finish line. Creating a thoughtful diet for running a marathon can help you feel prepared, steady, and supported throughout your journey.
This guide walks you through the essentials of marathon fueling — from everyday eating to race-day timing — in a simple, approachable way that fits into a balanced, wellness-focused lifestyle.
Why Marathon Nutrition Matters
During long-distance running, your body relies on carbohydrates for quick energy, taps into fat stores for endurance, and requires consistent hydration to stay balanced. Without nourishing your body properly, long runs can feel harder, your energy may dip sooner, and your recovery may feel slower.
Many runners unintentionally under-fuel during training, skip carbohydrates, or wait too long to practice race-day fueling. The good news? With a steady, consistent nutrition routine, you can support your training from the inside out.
Building Your Nutrition Foundation
Carbohydrates: Steady Energy for Long Runs
Carbohydrates provide your muscles with glycogen — the fuel they use during running. Aim to include them at most meals and snacks during training.
Great options include:
Oatmeal
Brown rice
Quinoa
Sweet potatoes
Whole-grain toast
Fresh fruit
Timing tip:
Enjoy a balanced meal with complex carbs 3–4 hours before long runs, and include a simple carb source (like a banana or dates) shortly afterward.
Protein for Routine Repair
Protein plays a role in supporting your muscles after daily training. You don’t need high amounts — just steady intake throughout the day.
Supportive options include:
Tofu or tempeh
Beans and lentils
Nuts and seeds
Plant-based protein shakes such as ALOHA Chocolate Sea Salt Protein Shake
Plant-based protein bars like ALOHA Peanut Butter Cup
A simple post-run option is a smoothie made with ALOHA Vanilla Protein Powder blended with fruit.
Healthy Fats for Satisfaction
Healthy fats help you feel grounded between meals and support overall wellness during training.
Add daily sources like:
Avocado
Almonds
Chia seeds
Olive oil
Cashews
Snack idea: Pair apple slices with almond butter — or grab an ALOHA Coconut Chocolate Almond Bar for an easy on-the-go option.
Your 16-Week Marathon Nutrition Rhythm
Base Training (Weeks 1–8)
Focus on consistency:
Balanced meals with carbs, protein, and colorful vegetables
2–4 nourishing snacks daily
Hydration from morning to night
Try incorporating pareve-friendly, plant-based snacks during busy training days, such as an ALOHA Chocolate Mint Bar or fruit with nuts.
Peak Training (Weeks 9–12)
Mileage increases — so calories need to increase too.
During long runs, practice:
Eating 30–60g of carbs per hour
Testing easy-to-digest fuel options
Practicing your hydration plan before race day
This is also a great phase to test post-run recovery smoothies with ALOHA Protein Powder, which is gentle and plant-based.
Taper + Race Week (Weeks 13–16)
During taper:
Reduce training
Increase carbs for 2–3 days
Stick to familiar foods
Keep hydration steady

Race-Day Fueling Made Simple
Morning-of Meal (3–4 hours before)
Choose familiar, easy meals such as:
Oatmeal with banana
Toast with honey
Simple breakfast smoothie
If you use bars on race morning, stick with a flavor you know your body loves, such as an ALOHA Peanut Butter Chocolate Chip Bar.
1–2 hours before

Banana

Smooth applesauce pouch
During Your Race

Banana bites
Hydrate steadily with small sips. Listen to your body.
