A cold beer after a run feels like a tradition. But does it support recovery—or sabotage it? Here’s what the science says.

Why runners love beer after running
From finish-line festivals to beer miles and pub runs, beer is deeply woven into running culture. Beer is more than a post-run drink—it’s a shared ritual, a social anchor, and a small reward at the end of the effort.
After a tough run, a cold beer feels like a well-earned trophy. Some runners believe it replenishes carbs, helps them relax, and even aids rehydration. Still, the reality of what beer does to your body post-run is less celebratory.
What your body really needs after a run
To recover well, your body needs three main things: fluids, fuel, and repair. That means:
- Rehydration: replacing the fluids and electrolytes lost through sweat
- Refueling: restoring muscle glycogen with carbs
- Repair: kickstarting muscle recovery with protein
Timing matters. Ideally, you want to start this process within 30–60 minutes post-run. And while beer contains some carbs and fluids, it’s missing key ingredients—and introduces others that may slow things down.
The pros: is there any benefit to drinking beer after running?
Let’s start with the good news.
Beer does contain some carbohydrates and fluid, which can offer a partial contribution to recovery—especially in light beers with lower alcohol content. For some runners, the mental reward of a beer post-run can lower stress and mark the end of a tough effort in a positive way.
There’s also research suggesting that light to moderate alcohol intake might have cardiovascular benefits in certain populations. A study found that low-level drinking was associated with reduced heart disease risk in some cases—but noted that benefits were modest and may reflect lifestyle factors more than alcohol itself.
Then there’s the social side. Post-run beers can strengthen bonds, foster motivation, and contribute to the joy of running—especially in community-driven environments.

The cons: what beer actually does to your recovery
Unfortunately, alcohol also disrupts key elements of the recovery process:
- It’s a diuretic, which increases fluid loss and impairs rehydration. That cold beer may leave you more dehydrated than before.
- It reduces muscle protein synthesis—by up to 37%, according to a study. That means your body can’t rebuild muscle tissue as efficiently.
- It delays glycogen replenishment, especially if no other carbs are consumed alongside.
- It increases inflammation, which might hinder recovery or exacerbate soreness.
- It affects sleep, especially REM cycles, which are crucial for physical and mental recovery. Poor sleep after a beer or two may mean subpar performance the next day.
What the World Health Organization says
In 2023, the World Health Organization issued a clear statement: “When it comes to alcohol consumption, there is no safe amount that does not affect health.”
Even small amounts of alcohol increase the risk of certain cancers and other chronic diseases. For runners—who often prioritize longevity, immune health, and consistent performance—this is worth considering.

So… is it ever okay to have a beer after a run?
The answer depends on the context.
If you just finished a fun run with friends, stayed well hydrated, and plan to have a balanced meal afterward? One beer probably won’t derail anything. But after a hard workout or long run, it’s better to choose water, electrolytes, protein, and carbs first—and wait a few hours before drinking, if at all.
Here are a few ways to minimize the impact:
- Hydrate first with water or a sports drink
- Eat a recovery meal with protein and carbs
- Consider non-alcoholic options
While beer offers a few carbs and a sense of reward, the science is clear: alcohol slows rehydration and adds stress to the body at a time when it needs recovery the most.
That doesn’t mean runners need to swear off beer entirely. But frequency, timing, and context matter. If beer is part of your running ritual, enjoy it mindfully. With the WHO’s warning in mind, treat beer as a social bonus, not a recovery tool.
