What to eat after a marathon (or a half marathon)

What to eat after a marathon, in one line: carbohydrate, protein, fluid and some salt, starting with whatever your stomach will accept at the finish and moving to proper meals within a few hours. Then keep eating normal, generous meals for the next two or three days. That's it. No recovery superfood, no magic window that slams shut at minute 31.

The same rules cover what to eat after a half marathon, just smaller. Below: the finish-line-to-day-three timeline, the numbers that actually come from a source, what to do when you can't face food, and the post-race beer question. If you'd rather not plan the training around all this by hand, an AI coach for running and lifting handles the schedule. The bagel is still your job.

One note up front: this is general practice, not a personal prescription. If you have diabetes, a GI condition, a history of disordered eating or anything else clinical, see a doctor or a registered dietitian before changing how you eat around races.

What to eat after a marathon: the short version

• ›Carbohydrate. You just burned through most of your stored fuel. Refill it: bread, bagels, rice, pasta, potatoes, cereal, fruit, juice, sports drink.
• ›Protein. A normal portion at each meal and snack. Meat, fish, eggs, dairy, tofu, legumes, a shake if that's easier.
• ›Fluid. Drink steadily over the next few hours rather than chugging a liter at the finish.
• ›Salt. Salty food or a sports drink helps you hold onto the fluid. Pretzels and soup were made for this afternoon.

That's the same list whether you ran a 4:30 marathon or a 2:00 half. The difference is how much, and for how long. If the half is your target race this year, the build matters as much as the food: a half marathon plan with strength built in keeps the long runs and the leg days out of each other's way, so you arrive at the start, and the finish, in decent shape.

Recovery food is also the mirror image of pre-run food. Before, you keep fat and fiber low so your gut stays calm. After, anything goes once your stomach settles. The pre-race side, including what to eat the night before a long run, is the hub this post hangs off.

The numbers, and when they actually apply

Every number below comes from the joint position stand from the American College of Sports Medicine, the Academy of Nutrition and Dietetics and Dietitians of Canada (Thomas, Erdman and Burke, 2016).

Read the first row carefully. The "speedy refuelling" target is for athletes with less than eight hours until their next demanding session. Nobody is running another marathon this evening. So you don't need to hit 1 to 1.2 g/kg every hour with a stopwatch. You need to eat plenty of carbohydrate across the day and the next one.

The protein number is easier. For a 70 kg runner, 0.3 g/kg is about 21 g. A normal meal built around meat, fish, eggs, dairy, tofu or legumes usually gets you into that range; read the labels if you want the exact figure. Repeat it at meals for the next few days.

Here's the multiplication for your own weight:

The carb column is there for completeness. It's mostly useful if you raced in the morning and have something demanding later, like a stage race or a back-to-back event weekend.

The finish-line-to-day-three plan

At the finish

Whatever your stomach will accept. Sports drink, a banana, the free bagel, a recovery shake, chocolate milk, a few pretzels. Small amounts, often. Plenty of runners feel queasy for the first half hour. That's normal. Sip something with carbs and salt and walk around.

Does eating early matter? A little. In a small study of 12 cyclists, Ivy et al. (1988) found that delaying a carbohydrate drink by two hours after exercise reduced the rate of muscle glycogen storage compared with drinking it straight away. That's a reason to have something with carbs reasonably soon. It isn't a reason to force down food you're about to see again.

First proper meal, within a couple of hours

A real meal with carbs, protein and salt. Burrito, pasta with meat sauce, a big sandwich and soup, rice with chicken, pizza. This is not the time for the lettuce bowl. Your gut is fine with fat and fiber again, so eat what sounds good.

That evening

Another full meal. Most runners are hungrier than they expect around now. Feed it.

Days 1 to 3

Normal, generous meals with carbohydrate and protein at each, plus snacks. The position stand notes that glycogen can be normalized within about 24 hours of reduced training and adequate fuel, but only "in the absence of severe muscle damage" (Thomas, Erdman and Burke, 2016). A marathon is not the absence of muscle damage. Bernat-Adell et al. (2021) found creatine kinase, a muscle-damage marker, stayed significantly raised for up to 96 hours after a marathon. So don't assume day two means back to normal eating just because you can walk downstairs.

What to eat after a half marathon

Same list, smaller doses, shorter timeline.

• ›At the finish: sports drink, banana, whatever's in the bag.
• ›Within a couple of hours: a proper meal with carbs and protein.
• ›The rest of the day: normal meals, maybe a bit bigger than usual.

Most half marathoners are back to normal eating by the next day. If you fueled well during the race, your stores won't be as empty as after a full. And if you're trying to get the before-and-during right next time, what to eat before a half marathon explained covers the breakfast and timing.

For shorter races and training runs, the answer shrinks again. This breakdown of what to eat after a run covers everything from a 5K to a Sunday long run.

When you can't face food

Common after a hot or hard race. Your stomach just spent hours being bounced, sugared and ignored, and it's not in a hurry to forgive you.

• ›Drink your calories. Sports drink, juice, chocolate milk, a smoothie or a recovery shake. Liquids tend to go down easier than a plate of food.
• ›Go bland and salty. Pretzels, crackers, plain bread, soup.
• ›Try again in an hour. Appetite usually comes back once you've sat down, cooled down and had something to drink.

If nausea, vomiting, confusion or a headache doesn't settle, or gets worse, get checked by the medical tent or a doctor. The position stand lists those among the symptoms of low blood sodium from overdrinking, which needs prompt medical attention (Thomas, Erdman and Burke, 2016). Don't self-diagnose it with a bag of chips.

Fluid and salt

Drink to thirst over the next few hours, and use urine color as a rough guide. If you weighed yourself naked before and after, the position stand suggests drinking about 1.25 to 1.5 L of fluid for every 1 kg lost, because you keep losing fluid through sweat and urine during recovery (Thomas, Erdman and Burke, 2016). Spread it out. Gulping it all at once mostly sends you to the bathroom.

The same source says athletes shouldn't be told to restrict sodium after exercise, especially after large sweat losses, because sodium helps you retain the fluid you drink. Salty food after a marathon is not a vice. It's a strategy.

The post-race beer

You earned it, and one drink with your friends at the finish isn't going to undo anything. A big night is a different story.

The position stand says alcohol after exercise may interfere with recovery by impairing glycogen storage, slowing rehydration and impairing muscle protein synthesis, and it encourages athletes to minimize or avoid alcohol after exercise when recovery is a priority (Thomas, Erdman and Burke, 2016). Practical version: eat and drink something non-alcoholic first, then have the beer, then eat again.

Don't diet the week after

The week after a marathon is a bad time to start cutting. You're repairing muscle, refilling glycogen and probably sleeping more. Eat to appetite, and don't read anything into the scale for a couple of weeks; refilled glycogen brings water with it.

This also isn't the week to fix your whole diet. The everyday stuff matters more across a build, and how to eat during marathon training is where that lives. For the next race, the fueling starts days before the start with carb loading for anything longer than about 90 minutes.

What about running and lifting?

Food is one half of recovery. Time is the other. Walk, sleep, run easy when your legs agree, and bring lifting back gradually. Our guide to marathon recovery has the week-by-week plan, including when heavy squats can come back.

How exrsz handles race recovery

exrsz builds a periodized plan from your goal, your schedule, your level and your equipment, with running and lifting balanced in one plan. After race day it keeps the following weeks easy, brings lifting back gradually, and adapts each week to how you actually trained. What you eat at the finish line is between you and the snack tent.

FAQ

What should I eat right after a marathon?

Whatever your stomach accepts: sports drink, a banana, a bagel, chocolate milk or a recovery shake. Then a proper meal with carbohydrate, protein and some salt within a couple of hours, and generous normal meals for the next few days.

What should I eat after a half marathon?

The same things in smaller amounts: something with carbs at the finish, a real meal with carbs and protein within a couple of hours, and normal meals after that. Most runners are back to their usual eating by the next day.

How much protein should I eat after a marathon?

The ACSM, Academy of Nutrition and Dietetics and Dietitians of Canada position stand suggests 0.25 to 0.3 g per kg of body weight, or about 15 to 25 g, after key sessions and every 3 to 5 hours across the day (Thomas, Erdman and Burke, 2016). A normal portion of meat, fish, eggs, dairy or tofu covers it.

Do I need to eat within 30 minutes of finishing?

Not to the minute. A small study found that delaying carbohydrate by two hours slowed muscle glycogen storage (Ivy et al., 1988), so having something reasonably soon makes sense. If you feel sick, sip a sports drink and eat when you can.

Is it OK to drink alcohol after a marathon?

One drink is unlikely to matter much. The position stand says alcohol after exercise may impair glycogen storage, rehydration and muscle protein synthesis, and advises minimizing it when recovery is a priority (Thomas, Erdman and Burke, 2016).
