Overall dietary guidelines:
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.
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. Discover what to eat on different training days with our training meal plans for runners.
We’ve included examples of the race training programme from London Marathon to plan your nutrition for this day.
* Beginner’s guidelines as recommended by the London Marathon.
It’s the day before the big race. Whilst carbohydrates are still the priority to fuel for the race ahead, it’s important to stick to the foods you know – now is not the time to start experimenting with extra spice or fatty dishes, which may cause a stomach upset.
Often the biggest mistake is trying to eat too much the day before and feeling uncomfortable on the morning of the race – stick to your normal routine here (only have a dessert or an evening snack if you usually have one), so you’re up and ready to eat breakfast before the race.
