1. You are what you eat

Are you one of the two million people in the UK that goes out for a run at least once a week? Do you think about what you eat before you force yourself out of the door? Or what you drink when you get back in with that post-run glow?

Whether you enjoy a short jog around the park on a Saturday morning or are training for an event such as a 10k or marathon, could what you eat make a difference to your performance?

3. Going the distance

Our bodies can only store enough glycogen (carbohydrate) to provide energy for 60-90 minutes of running (depending on pace and ability). It's when these stores run out that athletes can ‘hit the wall’, finding their energy is suddenly depleted.

Should you carb-load before a race?

You do need to make sure your body is stocked up on good carbohydrates, but this doesn’t mean carb-loading. Instead make sure you eat good carbohydrates in the days leading up to a race. Swap toast for a bagel with honey and banana, or have a jacket potato with beans instead of tuna, that way you fill your stores without overloading your stomach, which can be uncomfortable.

What should you eat for breakfast?

Try eating different types of breakfasts before you go out on a long training run to see how your body reacts to it. Porridge, overnight oats, a bagel with peanut butter and jam or scrambled eggs on toast are good options. Breakfast should be eaten between two to four hours before your race.

How much energy do you need to top up?

Depending on the distance your body will need 30-60g of carbs per hour to keep topped up during a long race. Jelly sweets contain 5g each, a banana contains 25g or a homemade energy drink made with 300ml fruit juice, 200ml water and ¼ tsp of salt contains 30g.

5. Should you go large on protein?

Protein has long been touted as the key to recovery after exercise, but does that mean we should all be reaching for the protein shakes after a run?

While protein does play a role in muscle building, repair and recovery, whether you need to up your daily intake will depend on how much you are training.

Gentle jogger

If you enjoy a couple of moderate jogs a week you probably don’t need any more protein than you already get from a healthy diet. For moderate exercise the suggested amount is around 0.8-1g per kg of your body weight a day (0.8g for women, 1g for men). This means that a woman that weighs 57kg would need around 46g per day. This could be achieved by eating two large eggs, 75g chicken and 400ml milk in her daily diet, which means there is no need to add more.

Event training

If you are an athlete or training hard for an event such as a marathon it is a slightly different story. All exercise does lead to a break down in the proteins in your muscles, so if you are training regularly, ensuring good protein choices can counteract this through muscle growth and repair. Frequency not quantity seems to be the key for athletes when it comes to protein. Current recommendations are that an athlete should consume 0.25g of protein per kg of their body weight three to six times a day. For an athlete that weighs 80kg that means 20g three to six times a day, which is equivalent to 240g (drained weight) of chickpeas, 100g of chicken or three large eggs.

Vegetarians and vegans

Proteins are made from amino acids, eight of which are essential and must come from your diet. They are found in a complete source in animal products, but if you follow a vegetarian or vegan diet you will need to combine different sources of protein to ensure you get all eight – dal and rice for example, or beans on toast. Soya protein is also a good alternative.

6. What should you drink after a run?

Based on the information above, which drink do you think would be a good option after you've been for a run?

Orange juice mixed with water

You selected

Orange juice mixed with water

While orange juice and water would help with rehydration, this is probably best consumed to top up your energy during a long run.

Chocolate milk

You selected

Chocolate milk

Yes. Chocolate milk contains carbohydrate (to replenish glycogen stores), calcium (to aid bone health) and protein (to build and repair muscles).


You selected


Water will help you to rehydrate after a short run, but if you have been training hard you may also need something more substantial, such as chocolate milk.
