London Marathon Breakfast

The Perfect Pre–London Marathon Breakfast — Plus an Easy Recipe Runners Swear By

Saturday 26th Apr 2025 |

You’ve trained for months, pinned on your race number, and now it’s finally here: London Marathon day. But before you lace up and hit the start line, there’s one crucial decision that could make or break your race — what to eat for breakfast.

Here’s how to fuel properly on marathon morning, plus a simple, delicious pre-race breakfast recipe that’s packed with everything your body needs to go the distance.


🏃‍♂️ Why Your Pre-Marathon Breakfast Matters

On marathon day, your breakfast isn’t just a meal — it’s part of your strategy.

A good pre-race breakfast should:

  • Top up glycogen stores (your body’s energy reserves)
  • Be easy to digest
  • Contain carbs, a little protein, and minimal fat or fibre (to avoid stomach issues)
  • Be familiar — race day is not the time to experiment!

Ideally, you should aim to eat 2.5 to 3 hours before the start gun to allow time for digestion and minimise any mid-race stomach discomfort.


🍌 What Should You Eat Before a Marathon?

Top choices for pre-race breakfasts include:

  • White toast or bagels with honey or jam
  • Porridge with banana and a drizzle of syrup
  • Low-fat yogurt with oats and fruit
  • Rice cakes with nut butter
  • An energy bar if you’re short on time

The focus is simple: high carbs, moderate protein, low fat, and low fibre.


🥣 The Perfect Pre-Marathon Breakfast Recipe: Banana and Honey Oatmeal

This quick, runner-approved oatmeal is ideal because it’s easy on the stomach, full of slow-releasing energy, and fast to prep — perfect for a nervy race morning.


Ingredients:

  • 1/2 cup rolled oats
  • 1 cup low-fat milk or plant-based milk
  • 1 small banana, mashed
  • 1 tablespoon honey
  • 1/2 teaspoon cinnamon (optional)
  • A pinch of salt
  • Optional: a small spoon of peanut butter for extra energy

Method:

  1. In a small saucepan, combine the oats, milk, mashed banana, cinnamon, and a pinch of salt.
  2. Cook over medium heat, stirring often, until creamy — about 5 minutes.
  3. Stir in the honey just before serving.
  4. Top with a few extra banana slices if you like, and a light drizzle of honey or a tiny spoonful of peanut butter for bonus energy.

Eat it around 2–3 hours before the race starts, then sip small amounts of water or electrolyte drinks in the lead-up to the start line.


Final Word

Nailing your pre–London Marathon breakfast can give you the steady energy you need to power through the course — from the Cutty Sark to Buckingham Palace. Stick to simple, carb-rich foods you’ve tested during training, and trust the plan.

After months of preparation, this final piece of the puzzle will help you stride confidently across that finish line — banana-fuelled and smiling.
