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.

Paula Radcliffe's top diet tip if you're training for a marathon

"Consume plenty of protein as well as carbs," says Paula. "You're going to need to tweak your diet and pay more attention to carbohydrate and protein because you're building muscle and breaking it down. People always think about the carbs and don't think so much about the protein side of it." See all of Paula's tips for success.

How to stay hydrated on a run

Want to know why your body needs to be hydrated during a long run or marathon, how often you should drink, which drinks to enjoy and if you should be taking electrolytes? Read our expert guide on staying hydrated on your run. Your hydration strategy should replace any water and electrolytes that have been lost through sweat. Make sure you start your race or long run fully hydrated – drinking approximately 500ml of fluid two hours before allows any excess to be passed as urine before you start.

How does Mo Farah stay hydrated on a run?

"Water obviously is the most natural thing you can have, but it leaves your body too quickly, and there are isotonic drinks that are better for you."

Like fluid, electrolytes are lost in sweat and may need to be replaced. You can top up your electrolyte levels with sports drinks and gels, which are an easy way to absorb and retain fluid during heavier sweat losses. Check out our review of the best electrolytes.
