What to eat after a long run? July 2026

Key takeaways

• Muscles refill glycogen fastest in the first 30 to 60 minutes after a long run.
• A good recovery refuel is carb-led, roughly 3:1 to 4:1 carbohydrate to protein, plus 20 to 25g protein.
• The window matters most if you ran fasted, ran long or hard, or raced again within 24 hours.
• Body Fuel gives 25g plant protein, fluid, electrolytes and prebiotic fibre with no prep, in a kit-bag carton.
• Body Fuel is low in carbohydrate, so pair it with a fast carb like a banana or dates to refill glycogen.

Introduction

You cross the line or stop your watch, legs hollow, and you are not even hungry. That awkward gap is exactly where most post-run recovery advice quietly falls apart.

The simple answer is to take some carbohydrates with a little protein within roughly half an hour. You do not need a perfect spread or a cupboard full of supplements.

This article covers what is happening in your body during that window. It then shows how much to eat, and the easiest thing to reach for afterwards.

Why does the first 30 minutes after a long run matter?

A long run burns through muscle glycogen, the stored carbohydrate your body uses for endurance. Refilling that store is the main job once you stop moving.

Your muscles refill glycogen fastest in the first 30 to 60 minutes, when they are most insulin sensitive. The enzymes that rebuild glycogen are most active then, so early carbohydrate gets used quickly.

This is the grain of truth behind the old anabolic window idea. It is real, but it is not a cliff edge you fall off. Miss it by an hour and you have simply refuelled a little more slowly.

How much carbohydrate and protein do you actually need?

Lead with carbohydrate, because that is what your drained glycogen stores want first. Recovery research points to a carb-led refuel at roughly a 3:1 to 4:1 carbohydrate to protein ratio.

A useful target is about 1g of carbohydrate per kilogram of bodyweight afterwards. For a 65kg runner that is roughly 65g, with a good chunk taken early.

Add around 20 to 25g of protein to support muscle repair after the effort. For most runs you do not need more protein than that in one sitting. If you want the details, see how much protein you need for recovery.

What should you reach for when you have no appetite?

Real food does the job well when you can actually face it. Good options include a banana with yoghurt, toast with eggs, or rice with chicken. Chocolate milk is popular because it lands close to that carb to protein ratio.

The catch is the one from the top of this article, though. After a long race your stomach often wants nothing to do with a meal. That is the exact moment a no-prep option earns its place in your kit bag.

You also lose fluid and electrolytes through sweat, so rehydrating is part of recovery too. Our guide to why electrolytes matter after sweating covers that side.

Your post-run refuel at a glance

Table summary: aim for around 1g of carbohydrate per kg, 20 to 25g protein, and fluids within about 30 minutes of finishing.

Where does Body Fuel fit your post-run routine?

Body Fuel is the ready-to-drink option for the moment you cannot face food. Each carton gives 25g of plant protein to start repairing the muscle you broke down. It also carries fluid, sodium, potassium and magnesium to help replace what you sweated out.

Inulin, a prebiotic fibre, supports the gut after the jostling of a long run. It is low in carbohydrate, so pair it with a banana or a few dates to refill glycogen.

The carton needs no prep, stays good for months, and lives happily in a kit bag. That makes it a simple finish-line option whether you run marathons or train for Hyrox. If you are building towards a first race, our marathon training guide pairs well with this.

Does the window matter for every run?

No, and it helps to be realistic about which runs actually need it. After a short, easy run on a normal eating day, do not overthink it. Your next proper meal will handle the recovery on its own.

The window matters most if you ran fasted, ran long or hard, or raced again within 24 hours. In those cases, refuelling sooner clearly helps you bounce back for the next effort.

For everyone else, your total carbohydrate and protein across the day matter more. Consistency beats precision, which is the thread running through our top recovery secrets.

Conclusion

Refuelling after a long run really is simpler than most advice makes it sound. Aim for carbohydrate with a little protein within about half an hour, leaning carb-led. Add fluids and electrolytes, and reach for something you can actually stomach. Hit it properly after a fasted, long or hard run, or before racing again tomorrow.

The rest of the time, just eat well across the whole day. Make recovery easy enough to repeat, and you will actually do it.

Keep a Whole Supp Body Fuel in your kit bag for fast, no-prep recovery after your next long run.

Frequently asked questions

Do I need to eat straight after every run?

No. For a short, easy run on a normal eating day, your next proper meal handles recovery on its own. The early window matters most after a fasted, long or hard run, or when you race again within 24 hours.

What is the best carbohydrate to protein ratio after a long run?

Lead with carbohydrate at roughly a 3:1 to 4:1 carbohydrate to protein ratio, plus around 20 to 25g of protein. Your glycogen stores want carbohydrate first, with protein there to support muscle repair, not to dominate the refuel.

How much carbohydrate do I actually need after a long run?

A useful target is about 1g of carbohydrate per kilogram of bodyweight, so roughly 65g for a 65kg runner. Take a good chunk of it early, while your muscles are still most insulin sensitive.

What should I have if I have no appetite after a long run?

Liquids are usually easier to get down than solid food. A ready-to-drink option like Body Fuel covers protein, fluid and electrolytes with no prep, and you can pair it with a banana or a few dates to add the fast carbohydrate your glycogen needs.

Does Body Fuel have enough carbohydrate to refuel glycogen on its own?

No. Body Fuel is deliberately low in carbohydrate, so it is not a complete glycogen refuel by itself. Pair it with a fast carbohydrate such as a banana or dates to cover that side properly.
