Runners: When and What to eat During Training

The next post in our “nutrition for runners” series looks briefly at the timing of what and when you should eat during your training.

Nutrient timing can play a role in your nutrition plan, and can get mind-blisteringly complex, but when in doubt, K.I.S.S.! (that’s Keep It Simple, Silly!)



Aim to have a full and balanced meal 4-6 hours before training, and a small high-carbohydrate snack (like a banana or a cereal bar) about 30-60 minutes before your session. If you train first thing in the morning and can’t stomach anything beforehand, make sure you’ve had a carbohydrate-rich meal the night before and have a high-carb snack readily available for straight after your session.


What time should I eat the last meal of the day?


Try to have a snack as soon as you can after training; ideally high-carbohydrate with a little bit of protein (if we’re getting technical, 3:1 carbohydrate:protein is a good ratio to aim for). For example, a couple slices of bread with peanut butter is a good place to start, or a good handful of trail mix, or a fruit yoghurt. This is often where a post-workout protein shake can come in useful – to see you through your stretches and shower, or whatever else you need to do. Within 2 hours of finishing your session, you should be sitting down to a balanced but carbohydrate-rich meal.

What should I eat during a long training run

If you feel like you are struggling with energy dips (“bonking”, or “hitting the wall”) during your longer training runs, and the rest of your nutrition plan is sufficiently high in calories and carbohydrates, you might want to experiment with taking on some fuel during the run. For most people, this will take the form of an energy gel or a sports drink (not the low-calorie sugar-free kind!).

Start with a gel or enough sports drink to provide about 30g of carbohydrate, about 40 mins in. Then refuel with 30g of carbohydrate every 30mins. If you still feel low on energy, try increasing the dose to 50-60g of carbohydrate, as long as your stomach can tolerate it.

This is where practice is absolutely crucial, as sports drinks and gels can vary hugely in taste, consistency, and formula, and some may just not agree with you – which isn’t something you want to discover on race day!
