What you do after the finish line matters just as much as the miles you ran to get there. Coach Amanda and I sat down with sports dietitian Meg Mahoney to break down the truth about post-race nutrition and why so many runners unknowingly sabotage their own recovery right after crossing the line.

Key Takeaways

•             Fuel early and often during a race. Waiting until you feel low means you’re already digging out of a hole.

•             Aim for a minimum of 60 grams of carbs per hour during a marathon effort, more if your gut can tolerate it.

•             Within the first 30 to 60 minutes post-race, prioritize liquid carbs, protein, and sodium, since eating a full meal often feels impossible right away.

•             “I’m running less, so I should eat less” is a trap. Your body is doing major repair work during recovery and needs even more fuel than you’d expect.

•             A short “shakeout” 5K the day before your goal race is not actually a shakeout once you’re standing on a start line with a bib on.

•             Tart cherry juice, taken consistently for about a week before and after a race, may help with inflammation and sleep.

Fuel Early, Fuel Often, Nothing New

The golden rule of race day fueling is nothing new: whatever you eat and drink on race day should already be proven in training. Beyond that, the biggest mistake Meg sees is runners waiting too long to start fueling, saving calories for later out of habit, and then trying to dig out of an energy deficit mid-race that is very hard to climb out of. Aim for at least 60 grams of carbs per hour at race effort, and more if your gut can handle it, since you’re burning significantly more than you do on a typical long run at that same distance.

Hydration and Sodium Are Deeply Individual

Sweat rate and sodium needs vary enormously between runners, and how much you visibly sweat is not a reliable indicator of how much sodium you actually need. Meg walked through a simple at-home sweat test: weigh yourself before and after an hour-long run, account for fluid intake during that hour, and the difference in pounds (16 ounces per pound) tells you your approximate hourly sweat rate. Runners with a high sodium need might require more than what a standard sports drink provides and should consider sodium supplements or salt pills in the 200-500mg range per hour.

The First 30 to 60 Minutes After You Finish a Race What to Eat

Your body is depleted at a cellular level right after a race: glycogen stores are largely gone, muscle tissue has broken down, and you’re likely dehydrated. Because eating a full meal often feels impossible immediately post-race, Meg recommends starting with liquids: a full-sugar electrolyte drink or sports drink, plus a protein source like chocolate milk or a protein shake. If you can tolerate a little solid food, add pretzels for extra sodium. Aim to get a real meal in within about two hours, ideally with carbs, protein, and some healthy fat to help manage inflammation.

“I’m Not Running as Much, So I’ll Eat Less” Is Backwards

This is one of the most common and damaging mistakes runners make during recovery. Even at rest, your body is doing enormous repair work after a hard race or training block, and your calorie, carb, and protein needs stay elevated well beyond what you’d expect from a low-activity week. Treat your recovery period the way you’d treat a taper: less training volume does not mean less fuel. It means more energy is available for your body to actually repair itself, and under-fueling here is a common, sneaky cause of injuries that show up seemingly out of nowhere once training resumes.

That “Shakeout” 5K the Day Before Your Marathon Isn’t One

A genuine shakeout run is short, easy, and low-key. A timed 5K race the morning before your marathon, even at an easy effort, still carries race-day adrenaline and intensity that a true shakeout does not. If you’re stacking a bonus race onto race weekend for the medal, understand that it is not a neutral addition to your taper.

Frequently Asked Questions

How many carbs should I eat per hour during a marathon? A minimum of 60 grams of carbohydrate per hour is a reasonable baseline for marathon effort, and more can be beneficial if your gut can tolerate it. The right amount depends on your pace, goals, and personal gut tolerance, which is why practicing your fueling plan on long runs in training matters so much.

What should I eat immediately after finishing a race? Start with liquids in the first 30 to 60 minutes: a full-sugar electrolyte or sports drink plus a protein source like chocolate milk or a protein shake. Add pretzels or other salty snacks if you can tolerate solid food. Aim for a full meal with carbs, protein, and some healthy fat within about two hours of finishing.

Should I eat less after a race since I’m not training as much? No. Your body needs significant energy to repair muscle tissue, replenish glycogen, and reduce inflammation during recovery, even though you’re running less. Under-eating during recovery is a common and often overlooked cause of injuries that surface once training ramps back up.

How can I figure out my sweat rate and sodium needs as a runner? Weigh yourself immediately before and after a run of about an hour, accounting for how much fluid you drank during that time. Each pound lost equals about 16 ounces of sweat. Pair this with attention to how salty your sweat feels (visible salt residue, skin that tastes salty) to estimate whether you need extra sodium beyond a standard sports drink.
