Eat right in the week leading up to an endurance event. Sports nutritionist James Collins explains why, by Wednesday, your protein intake should be on the rise.
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 into 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.
20 minutes easy run
* Beginner's guidelines as recommended by the London Marathon.
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.
Apple & linseed porridge
Start the day the right way with a nutrient-rich, oaty breakfast. This is full of stomach-friendly fibre – great for digestion.
Sweet & spicy nuts
Add flavour to protein-rich nuts with cinnamon and mixed spices.
Frozen fruit sticks with passion fruit & lime drizzle
This colourful mix of fruit adds a hit of natural sweetness to your day.
