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.
With an increase in the number of runners following a vegetarian diet (or even ‘flexitarian’ one, including meat with some meals), we have put together a plan for a week’s worth of meals leading up to the marathon to suit those requirements. A well-structured vegetarian diet should deliver the main macronutrients (carbohydrate, protein and fat) required during training, but vegetarians should also make sure they are getting enough iron and B12 (both important for energy production).
While these recipes provide a good framework, there will also be times where an extra serving of higher-protein foods (such as dairy, pulses, grains, nuts and seeds) can be added to meals to increase the overall daily intake.
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.

Protein-rich foods at each meal are the priority for today with a light training session. Carbohydrates are lower today before increasing tomorrow, leading into the race. Try out some new meal options with a range of fruits and vegetables to provide micronutrients (vitamins and minerals) for the regeneration of muscles.
This hearty breakfast option has added fruit and nuts to help keep you satisfied until lunch.
Add flavour to protein-rich nuts with cinnamon and mixed spices.
Quinoa is a good source of vegetarian protein – paired with crisp, grilled halloumi it makes a really delicious lunch.
This colourful mix of fruit adds a hit of natural sweetness to your day.
