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.
The big day is here. Breakfast provides the final opportunity to top up fuel stores ahead of the race.
The most important thing is to stick to your plan here, selecting a breakfast you have eaten before and are comfortable with. If you are travelling for the race, remember to plan ahead and choose an option that will be available in the hotel – or take it with you.
Often the biggest mistakes here are trying to eat too much the day before and feeling uncomfortable on the morning of the race. Remember, your increased carbohydrate intake over the last few days will have been stored as fuel, so you will be ready to race.
Post-race, the priority is to refuel. A drink is a great option to provide some carbohydrate, water and protein too, which will kick-start the repair process.
Orange & raspberry granola or poached eggs with smashed avocado & tomatoes
While these are both great options, remember to choose a breakfast that you have tried before a race in the past and works well for you.
Snack (during the race)
Water and easily digested carbohydrates from sports drinks, gels or jellied sweets are best – aim for something each hour.
Post-race recovery snack (within 30 mins)
Blend a mix of pomegranate juice, soya, banana and honey for a nutritionally-balanced smoothie.
Post-race recovery meal/lunch
BBQ chicken burgers
These tasty chicken burgers are super quick to make – perfect for a post-race treat.
Chilli con carne served with rice
Our classic beef chilli recipe contains plenty of protein – key to kickstart the recovery process.
Evening snack (optional)
A healthier version of traditional fruit and nut bars that are packed with seeds, oats and agave syrup.
