What to eat the week before the marathon

Contrary to previous beliefs, the week before the marathon isn’t all about piling on the pasta. In fact, to maximise carbohydrate (fuel) stores before the race, runners only need to start ‘fuelling up' or ‘carb-loading' two or three days before the race (three days if you prefer slower increase in your daily intake). Read more in our guide to carb-loading.

Earlier in the week, it may be useful to start including snacks to train the gut in preparation for increased carbohydrate intake in the days leading up to the race. Discover what to eat during the rest of the week with our marathon meal plan.

As a general rule, what you eat should be different depending on the training demands for that day (or when you are preparing for the race itself) to promote sufficient fuelling and recovery. The Tuesday before the marathon should ideally be a rest day – use this day to focus on nailing your nutrition. Discover what to eat on low and easy training days.

Tuesday training:

Rest day – no training

Tuesday nutrition:

Carbohydrate is reduced today, as it’s a rest day. Starting the day with a protein-rich breakfast is a good option to support muscle growth and repair while training volume is lower. Earlier in the week is a great opportunity to boost micronutrient intake, such as magnesium, iron and omega-3 fatty acids, which are crucial for energy production and muscle function.

Breakfast

Breakfast egg wraps

Adding a few tablespoons of oats to these egg wraps gives them a protein boost. We like them filled with mushrooms and tomatoes for a quick, filling and healthy breakfast. They provide iron, folate and fibre, too.

Morning snack

Apricot, honey & pistachio flapjacks

It's always good to have some healthy snacks on hand so you're not tempted to reach for processed protein bars. These tasty treats take just five minutes to prepare and can be enjoyed all week.

Lunch
