What to eat after a run

Should I focus on protein or carbs for my post-run recovery?

Both of these macronutrients are critical for full recovery after training. Carbs are the body’s main fuel source for high-intensity work – these are stored as glycogen in the muscles and liver. As the body can only store a certain amount, once reduced these stores need to be replenished before your next workout.

Protein is vital for the growth and repair of muscle tissue, after hard training this can take place for as long as 72 hours. Regular protein intake helps to provide the building blocks (amino acids) for ongoing muscle growth and repair.

20g of protein is the magic number that you need to kick-start the recovery process (with slightly more for bigger athletes and less for those of a smaller body frame).

I’m watching my weight, how do I balance eating for recovery with continued weight loss? And how much should I eat?

Many marathon runners are hoping to get a bit fitter and reduce body fat as part of their training process. It is possible to properly recover after exercise while encouraging healthy weight loss – it’s just about getting the balance right. The key is matching fuel intake to your training volume. This will mean eating more carbs on days with harder training sessions, while recovery days require fewer carbs and a greater focus on lean protein and healthy fats.

When managing your weight, try to get most of your carbs from low-GI foods at mealtimes, rather than lots of higher-GI snacks. These will help curb your appetite because they keep you feeling fuller for longer.

Where possible, eat meals as part of your recovery instead of adding extra recovery snacks. This may take a little more planning so that you coincide your runs with your mealtimes but it’ll be worth it as you reach your weight loss goals.

How many calories you should eat to lose weight is unique to you and depends on your age, gender, physical build and activity levels.

How long after running a marathon would it be sensible to start training again?

Before you rush to lace up your trainers, listen to your body. Physiologically, your body can be ready to start training after a few days, especially as fitness levels are often greatly improved with endurance training. However, don’t underestimate the cumulative physical and mental fatigue involved in running a marathon.

It is usually advisable for runners to take a break of a week to get a much earned physical, and psychological break, from their training.

What are the key components of a post-marathon recovery plan?

When you think recovery, think of ‘The Four R’s’:

Refuel – Have a carb-rich snack followed by a meal as soon after the race as possible.
Rehydrate – Replace fluid losses by drinking at regular intervals post-race.
Repair – Include a serving of protein (see above) with your recovery meal.
Rest – Get a good night’s sleep – this is when most of your muscle repair will occur.

Can protein bars and shakes form part of my recovery strategy?

Protein bars and shakes are often used for convenience but be aware that their nutritional profile will vary greatly depending on the ingredients used. For this reason, it’s important to check labels carefully to ensure the product meets your requirements. Although these products may have a part to play in recovery, it’s best not to rely on them but rather use them when time and location limit access to more nourishing options. Read our review of the best protein bars and powders.

It’s also worth noting that early studies in post-exercise nutrition suggest a carb to protein ratio of about 3 to 1 is likely to optimise glycogen stores and recovery.
