What is runner’s high? Learn how running endorphins work, how the experience varies depending on pace and perceived effort, and why beginners may feel it differently – or not at all.
Runner’s high is a real thing, but it’s often misunderstood. Many beginners expect a sudden rush of happiness or euphoria, and when that doesn’t happen, it’s easy to wonder if something is wrong.
Runner’s high is commonly described as an intense feeling of joy, but for many runners (especially at the beginning) it shows up way less dramatic – or not at all. It isn’t a universal milestone or a progress benchmark.
In this post, we’ll dive into what runner’s high actually is, how running endorphins work, and why everyone experiences it differently. The goal isn’t to chase a specific feeling or turn it into another goal to strive for, but to understand what’s happening as your body and mind adapt to running, so your expectations stay grounded and your progress easier to recognise.
What is runner’s high?
Runner’s high is described as euphoria or an intense feeling of joy, but more often than not it shows up as a general sense of calm, a lighter mood, or a feeling of mental clarity during a run. For some runners, it can feel almost meditative, like a rare moment where effort fades into the background and the mind feels quiet and focused.
For many people, it’s subtle enough to miss if you’re expecting a dramatic moment rather than a steady, balanced state of focus and enjoyment. This experience also gets confused with other very normal post-run feelings. You might feel proud because you finished a run, relieved that it’s over, or satisfied that you pushed through something hard. These are all positive and valid feelings, but they’re not the same thing as runner’s high.
Social media descriptions tend to exaggerate runner’s high as an intense, euphoric, effortless experience. In reality, it’s personal, pretty unreliable, and often much subtler than expected. Many runners experience it only occasionally, and some never experience it in a dramatic way at all.
Running endorphins explained
Endorphins are often mentioned whenever runner’s high comes up. The body produces these natural chemicals to help regulate pain and discomfort, reduce anxiety, and support mental focus. Endorphins are released during sustained physical activity and can reduce our perception of effort. These effects are helpful, but they don’t automatically create happiness or euphoria.
While endorphins play a supportive role in how running feels physically, they don’t fully explain runner’s high. Research has shown that endorphins can lessen pain in muscles, but they don’t easily cross the blood-brain barrier, which means they’re unlikely to be the sole cause of mental or emotional effects associated with runner’s high.
More recent research points to another group of chemicals called endocannabinoids. Unlike endorphins, they can cross into the brain and affect mood regulation, stress reduction, and feelings of calm and joy. Aerobic exercise triggers endocannabinoids release, which helps explain why runner’s high tends to show up more often during steady efforts than during short, intense bursts of activity.
Both endorphins and endocannabinoids support the running experience, but they don’t guarantee a specific emotional outcome. These systems are highly personal, and their effects depend on multiple factors like effort, duration, stress levels, sleep, and your running experience.
Feeling calmer, less uncomfortable, or more focused during or after a run already reflects these processes at work, even if it doesn’t feel like the intense runner’s high you’ve heard about.
Runner’s high for beginners
For most beginners, runner’s high doesn’t show up early on – that’s completely normal and not a sign to push harder or quit altogether. Many people run for weeks or even months without ever feeling this uplifted state they’ve heard about.
Early running puts the body and the nervous system under a lot of stress. Your muscles, joints, and connective tissue are still learning to tolerate impact, while your heart rate and breathing are working harder than ever before. When the body focuses on adapting and adjusting, discomfort tends to outweigh subtle feel-good signals.
There’s also a significant mental load in the beginning: learning a new skill from scratch, overcoming the fear of being judged, relying only on motivation before consistency forms. Constant uncertainty and overthinking can make it harder to notice positive sensations, even when your body is responding well.
Because of this, beginner running often feels harder than expected, long before it starts to feel enjoyable. Early struggles aren’t a verdict or a prediction of how running will feel later on; they’re simply a phase of adaptation that every runner goes through at the beginning.
Pace vs effort
Runner’s high links more closely to perceived effort over time than to your speed alone. Pace is an external, objective number – how fast you’re moving. Effort is internal and subjective – how hard that pace feels to your body and mind. Two runners can move at the same pace and experience completely different levels of effort.
That’s also why a run can feel manageable one day, and a similar run the next day may feel exhausting and overwhelming, even when the pace doesn’t change much. Factors like sleep, recovery, stress levels, and your running experience all influence how much effort a given pace requires. For beginners especially, even slower paces can feel intense, as the body is still adapting.
Sustained effort, duration, comfort, and confidence seem to matter more for experiencing runner’s high than hitting a specific pace. For beginners, it may appear during slower, steadier runs once the body settles into a rhythm. As running becomes more predictable and less demanding, there’s more space for that calm, focused state to show up. For more experienced runners, it may show up at higher intensities. And for some people, runner’s high won’t show up regardless of pace or effort – and that’s okay.
None of these outcomes are a problem to fix. They reflect differences in experience, adaptation, and how each body responds to training. Understanding the difference between pace and effort helps set more realistic expectations and take pressure off trying to push harder to “unlock” runner’s high.
Progress signs before runner’s high
For most beginners, runner’s high won’t be the first sign that running is starting to feel easier. Progress usually shows up earlier – and in much subtler ways. Those signs are easy to overlook if you’re waiting for a dramatic shift.
One common change is that running starts to feel less chaotic: movement becomes more coordinated and smoother, heart rate settles more easily, breathing feels easier to control, and the overall sense of panic slowly fades. Even if the pace still stays the same, effort starts to feel more manageable.
Another important sign is how you feel after the run. Even when the effort itself felt challenging, you might feel calmer, clearer, and more grounded afterward. Before your next run, you may notice that you don’t feel stressed, but excited and motivated. These post-run mood improvements and the growing desire to run again are often the strongest indicators that your body and minds are adapting to running, long before runner’s high ever appears.

Runner’s high vs race-day adrenaline
Runner’s high often gets confused with the overwhelming emotion or surge of energy people feel during races or events. While both can feel intense, they come from different places.
Race-day adrenaline is driven by external factors: nerves, excitement, crowd energy, competition, and the pressure of the moment. These elements can temporarily boost energy, reduce discomfort, and make running feel more effortless than usual. Although that rush can be very motivating, it’s closely tied to the situation.
Runner’s high, on the other hand, is more internal and less predictable. It isn’t triggered by an audience or a start line, and it doesn’t depend on performance. It tends to show up during sustained, mildly challenging effort, when running feels familiar and steady, rather than emotionally charged.
Feeling euphoric during a race is great – and not feeling it while training doesn’t mean you’re doing something wrong. These are just entirely different experiences, shaped by different factors.
Individual runner’s high experiences
Runner’s high doesn’t show up the same way for everyone. That difference isn’t random, and it isn’t something you can fully control. Multiple factors affect how strong runner’s high feels, what triggers it, and whether it even happens at all:
Neurochemistry differences
There are natural variations in how our brains and nervous systems respond to exercise. Some people are more sensitive to mood shifts during physical activity, while others feel subtler changes – or none at all.
Hormones and life balance
Hormonal fluctuations, stress levels, sleep quality, and overall mental load all affect how running feels. When the body is under ongoing stress, it often prioritizes regulation and recovery over mood-boosting, feel-good sensations.
Fueling and recovery
Underfueling, inadequate rest, or ignoring recovery can blunt positive responses to running. Feeling depleted makes it harder for calmer or more uplifting emotions to show up.
Run structure and duration
Short, interval runs don’t always create the same conditions as longer, more sustained efforts. For many runners, steadier runs are more likely to support focused or calm states.
Experience and familiarity
As running becomes more familiar, both physically and mentally, there’s often more space to notice how it feels. Early runs demand focus and attention just to get through them.
Studies suggest that around 69–77% of runners report having experienced runner’s high at least once. That number likely reflects not only real differences in experience, but also how difficult that feeling is to define and how differently people perceive and describe it.
Because of these differences, not feeling runner’s high doesn’t mean something is wrong or missing. It’s just a reflection of your body’s response to running under the current conditions. Some runners never experience it at all – and still manage to perform, progress, and enjoy themselves along the way.
For me, runner’s high has been rather inconsistent over the years. Sometimes it happens when I don’t really expect it, and sometimes not at all, even when my weekly mileage or average pace increase. I don’t rely on it or chase it, but I appreciate when it decides to show up. I’ve learned to really enjoy this almost meditative state when it does.
Seen this way, runner’s high is best described as a possible positive side effect of running, not a goal to chase or a marker of progress. Consistency and adaptation matter more than one specific feeling showing up.
Runner’s high as a goal
Runner’s high isn’t something worth chasing or putting pressure on. Treating it as a goal often creates more problems than it solves, especially for beginners.
When people try to trigger runner’s high on purpose, they often end up running too fast, pushing effort beyond what the body is ready for and can realistically sustain. Over time, this can lead to fatigue, overtraining, burnout, or even injury. Instead of making running feel easier and better, it makes it harder to stay consistent.
What matters far more, especially early on, is building tolerance – giving your body enough time to adapt to impact, effort, and repetition. Consistency allows running to feel more familiar and less demanding, and creates the conditions for runner’s high to show up naturally.
Focusing on building a routine takes pressure off each individual run, as not every one has to feel great to be effective. Showing up regularly, running at efforts you can recover from, and letting the adaptations happen over time does far more for long-term progress than trying to hit a specific emotional state.
Runner’s high can be an amazing side effect of running, but it feels best when it’s allowed, not pushed.
Runner’s high FAQ
There’s no set timeline – many beginners don’t feel runner’s high in the first weeks or months, and some never experience it in a noticeable way. Early running progress often shows up way before runner’s high ever appears.
Individual differences in neurochemistry, stress levels, sleep, hormones, fueling, and recovery all influence how running feels. Not experiencing runner’s high doesn’t mean running isn’t “working.”
Yes. Sustained movement of any kind can support endorphin release. You don’t need to run fast or continuously to feel mood-regulating effects.
Yes. Runner’s high seems to link more closely to perceived effort and duration than to speed. For beginners, it’s more likely to show up during steadier, easier runs than during fast or exhausting ones.
No. Runner’s high isn’t a reliable indicator of fitness or progress. Consistency, recovery, and how running fits into your life are far better markers of long-term improvement.
Moving forward
You don’t need to feel runner’s high early on in your running journey – or ever – for running to “count”. At the same time, when it does show up, it can be a genuinely enjoyable and motivating part of running. It just isn’t something that needs to be forced or expected.
Giving yourself permission to run without pressure often creates a better experience than trying to force one. Over time, consistency changes how running feels physically and mentally, even when progress doesn’t look dramatic at first. That itself can make runner’s high more likely to happen naturally.
Running doesn’t have to deliver a high to be effective. Showing up regularly, in a way that fits your life, is already enough.
