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 needs 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.

Carbohydrate intake is maintained at breakfast and lunch to support training volume for today. Protein and healthy fat intakes are also important for the ongoing growth and repair of the muscles. Options are nutrient-rich and provide sufficient fibre for healthy gut function. Snacks are included as optional depending on your preferences.
