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.
Runners who have coeliac disease, are intolerant to gluten or simply following a gluten-free diet need to plan their meals carefully around the appropriate carbohydrate options to prepare for the race. We have adapted our week-long marathon meal plan to provide options for the week leading up to the event, as well as examples that can be used as part of your wider training or day-to-day routine.
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 marathon.
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.
