Eating after a hard effort, a long training run or an ultra can look very different for me, but there's one constant: eating the right stuff. I'm not obsessive over every mouthful, but I do stop and think about what I'm putting back into the body, and whether it's going to help me recover.
After years of trial and error, I've learned that what and when you eat after a run matters as much as the run itself. Here's how I approach it, what the science broadly agrees on, and the go-to foods and recovery drinks that actually work for me.

The Quick Answer
What should you eat after a run? Aim for a mix of carbohydrates (to refill your energy stores) and protein (to repair your muscles), ideally within a couple of hours of finishing. After an easy run, a normal meal is plenty. After a long run or hard session, think bigger: something like cereal with Greek yoghurt and banana, peanut butter sandwiches, or a proper recovery shake. The harder and longer the effort, the more it matters. And if your stomach won't take solid food after a big effort, a liquid recovery drink does the job instead.
That's the headline. Now let's get into the detail, because the right answer genuinely changes depending on what kind of run you've just done.
Does It Really Matter What You Eat After a Run?
Yes, but let's keep this simple. When you run, you burn through stored carbohydrate (called glycogen) and you put your muscles under stress. Eating afterwards does two jobs: it tops the tank back up, and it gives your muscles the building blocks to repair. Get it right and you bounce back quicker and feel better for your next session. Skip it, and you'll often feel flat, sore and undercooked the next day.
The key thing I've learned is that you don't need to be perfect. You just need to be intentional. A bit of thought about what you're reaching for goes a long way.
When Should You Eat After a Run?
You've probably heard about the "30-minute window", the idea that you have to slam food down the second you stop or you've missed the boat. The truth is more relaxed than that. Yes, your body is primed to soak up nutrients in the first hour or two, so sooner is better after a hard or long effort. But what really matters is your total intake across the whole day, not racing a stopwatch.
When the window genuinely counts is when you've got another run coming soon: a double day, or back-to-back long runs in a training block or a multi-day event. In that case, refuel quickly. For most everyday runs, getting a good meal in within a couple of hours is absolutely fine. Don't panic if you can't eat immediately, especially after a big effort when your appetite has gone walkabout.
Carbs, Protein and Fat: What Your Body Actually Needs
Keeping it un-scientific:
Carbohydrates are your priority after most runs. They refill the energy stores you've just emptied. Think bread, cereal, fruit, rice, oats, honey.
Protein repairs and rebuilds muscle. A portion of around 20 to 30g after a run does the trick, which is roughly a couple of eggs, a pot of Greek yoghurt with a scoop of protein, or a chicken breast. You don't need to drown in it; more isn't better past a point.
Fat is not the enemy. The old advice to avoid it after running is overblown. It's fine in a recovery meal, and only slows things down if you're trying to refuel in a hurry for another session soon. Nuts, peanut butter and a bit of cheese are all welcome.
A combination of carbs and protein together is the sweet spot, and it's why classics like Greek yoghurt with fruit, or even a glass of chocolate milk, keep coming up as great recovery options.
What to Eat After a Short, Hard Run
A fast interval session might only clock up 4 or 5 miles, but the effort is extremely high. You've not burned a huge amount of fuel, but you've stressed the muscles, so I lean a little more towards protein here.
I'd reach for a banana, maybe some Greek yoghurt, possibly a slice of malted bread with peanut butter, or definitely a protein shake. Nothing dramatic, just a quick, decent hit of carbs and protein to mop up the effort. (Shakes and powders deserve their own deep dive, so I'll cover those properly in a follow-up article.)
What to Eat After a Long Run
Now we're talking. A long training run of 20 to 30 miles is common in my training blocks, and the refuelling job is much bigger.
If I've driven out a little way from home to start the run, I'll usually take something to eat for not long after I finish. That might be a Kellogg's Nutri-Grain bar, a banana, or even a gel to get the process started before I'm anywhere near a kitchen.
Once I'm home (if I'm under half an hour away), I head straight to the cupboard for nuts, cereal with Greek yoghurt, honey and a banana, or a couple of peanut butter sandwiches. What I eat often stays pretty similar, and that's deliberate: I know what I like, I know what the palate is happy to taste, and, crucially, I know what sits well in my stomach. After a long run is not the time to experiment.
What to Eat After an Ultra (When Your Stomach Says No)
This is where it all changes. Take the 2023 London2Brighton 100K. I'd been out for many hours, around 14, and at the finish there was burger and fries being cooked. They smelt incredible. I grabbed a plate and, almost instantly, before I'd even taken a bite, my stomach said: are you kidding, mate?
I just cannot eat solid food in the couple of hours after an effort like that. And that's the big lesson with ultras: the textbook advice to refuel immediately runs straight into the reality that your gut has shut up shop. After that long on your feet, blood has been diverted away from digestion and your appetite is often nowhere to be found.
That's where liquid recovery comes into its own, something you can sip that delivers carbs, protein and salts without asking your stomach to process a meal. These days I use products from the INFINIT range for exactly this. Back then, when I was still learning how I respond after an ultra, I definitely under-fuelled, simply because I didn't appreciate what I'd feel like after 14 hours in the shoes. If you're new to long stuff, plan your recovery in liquid form before you start, and don't assume you'll fancy that finish-line burger.
Does Distance, Effort and Heat Change Things?
Absolutely, and this is the bit a lot of generic advice misses.
Effort and distance decide how much you need. An easy 40-minute jog barely dents your stores, and a normal meal covers it. A hard tempo, a long run or an ultra empties the tank, so you need more carbs and a proper recovery effort.
Heat is a sneaky one. Running in hot weather burns through your stores faster and suppresses your appetite at the same time, so you need more, but want less. That's a horrible combination, and it's another reason cold, liquid recovery (a chilled shake or recovery drink) often goes down when food simply won't. Hot conditions also mean you've sweated out a lot of fluid and salt, so rehydrating with something that contains sodium, not just plain water, matters more than usual.
The rule of thumb I live by: match your recovery to the size of the effort. The bigger and hotter the run, the more the carbs, salt and fluids matter.
Recovery Drinks: When Food Won't Go Down
When your appetite has vanished, after an ultra, a hard race, or a hot session, a recovery drink is the easiest way to get what you need. Two I'd point you to sit at slightly different ends of the spectrum, which is worth understanding before you buy.
INFINIT :REPAIR Complete Recovery is a carbohydrate-led recovery drink. With around 60g of carbs to 16g of protein per serving, plus electrolytes and a blend of proteins, it's built to refill a big energy deficit. That makes it my pick after a long, depleting effort where refuelling is the main job.
High5 Recovery Drink takes a more balanced approach: 20g of protein to 20g of carbs, with a strong electrolyte and vitamin package. It's a cleaner protein hit with a lighter carb load, which suits shorter or moderate sessions, or any time you know a proper meal is coming soon afterwards.
Here's the simple comparison:
INFINIT :REPAIR | High5 Recovery Drink | |
Carbohydrate | ~60g | 20g |
Protein | 16g | 20g |
Carb-to-protein ratio | ~4:1 (refuel-focused) | 1:1 (balanced) |
Electrolytes | Yes | Yes (plus added vitamins) |
Best for | Long runs, ultras, big depletion | Shorter/moderate runs, or before a meal |
Neither is "better" outright; they're built for different jobs. After an ultra I want the carbs, so I lean INFINIT. After a sharp midweek session with dinner an hour away, a balanced drink like High5 is plenty. (I'll go much deeper on protein powders and shakes in a dedicated article soon.)
My Go-To Post-Run Foods
I'm a creature of habit, and I stick to what I know I like and what sits well. My regular rotation:
Banana (the runner's default, and for good reason)
Greek yoghurt with honey, banana and cereal
Peanut butter on malted bread, or peanut butter sandwiches
A handful of nuts
A Kellogg's Nutri-Grain bar or a gel for the immediate post-run hit when I'm out
A protein shake after a hard session
A recovery drink when my stomach won't take solids
And yes, you can absolutely include Nutella in that. And a Krispy Kreme or two. Recovery should keep you sane as well as fuelled, and a treat after a big effort has more than earned its place.
FAQ
What should I eat immediately after a run? Something with carbs and a bit of protein. After an easy run, your next normal meal is fine. After a hard or long run, reach for a banana, Greek yoghurt, a peanut butter sandwich or a recovery shake within an hour or two.
How long after a run should I eat? Sooner is better after hard or long efforts, ideally within a couple of hours, but the whole day's intake matters more than hitting an exact window. Only rush it if you've got another run coming soon.
What if I'm not hungry after a run? This is completely normal, especially after long or hot efforts. Go liquid: a recovery drink, a shake or chocolate milk will get carbs, protein and fluid in when food won't go down.
Is chocolate milk really good after a run? Yes. It has roughly the right carb-to-protein balance plus fluid, which is why it performs as well as many commercial recovery drinks. It's a cheap, easy option.
Should I eat carbs or protein after running? Both. Carbs refill your energy stores and protein repairs your muscles. A combination of the two is the sweet spot.
What should I eat after a long run or ultra? Prioritise carbs to refuel, alongside some protein, and replace fluids and salt. If your stomach has shut down after a big effort, a liquid recovery drink is the most reliable way to get it all in.
Do I need a recovery drink, or is food enough? Food is enough for most runs. Recovery drinks earn their place when you can't face solids, when you're short on time, or after a big depleting effort where you want carbs, protein and electrolytes in one easy hit.
What's your go-to post-run food? I'd love to hear what works for you. Drop it in the comments.
At the end of the day, recovery nutrition isn't about being perfect, it's about being intentional. It has taken me years of long runs, hard sessions, self-designed doughnut ultras and more than one finish-line meal I simply couldn't face to learn what my body actually wants when I stop. Yours will look different to mine, and that's exactly how it should be. Find the foods and drinks that sit well in your stomach, lean on them, and tweak as you go.
Now lace up, enjoy the miles, and go and earn that Krispy Kreme.
