Runner's high is a short-lasting feeling of euphoria or bliss that occurs after intense or lengthy exercise, such as running. It is often described as a sense of extreme joy or delight, and it can help athletes feel relaxed, calm, and shielded against pain from the long bout of exercise, at least temporarily.

This sensation is associated with the release of endorphins, which are chemicals that act like natural opioids and cannabinoids in the brain. While not everyone who runs or exercises intensely will experience a runner's high, it is a well-known and sought-after phenomenon among many athletes.

To summarise, "Runner's high" refers to a euphoric state that runners often feel during or after a run. This sensation includes feelings of happiness, well-being, and a diminished awareness of pain. It's commonly linked to the body's release of endorphins, which are natural painkillers and mood boosters produced during exercise.


  1. Variability: Not every run leads to a runner's high, and the experience varies from person to person. Factors like physical and mental state, fitness level, run intensity, and external conditions like weather and terrain can influence its occurrence and intensity.
  2. Scientific Theories: There's no definitive explanation for the runner's high, but one popular theory suggests it's related to the endocannabinoid system in the brain, which is activated by physical activity. Other theories point to a mix of endorphins and neurotransmitters like dopamine, which are linked to feelings of reward and pleasure.
  3. Benefits: Many runners seek this high for the surge of positivity and euphoria it brings. It can be motivating, helping runners push past their limits and enjoy their running experience more fully.
  4. Personal Experiences Vary: It's important to note that not all runners experience a runner's high. Some may feel negative emotions during running, and experiences can vary widely.
  5. Running for Personal Goals: Running is a personal journey, and achieving a runner's high should not be the only goal. Runners are encouraged to run for their own reasons and motivations.

In conclusion, while the runner's high is a well-known and often enjoyable part of running for many, it's not essential or guaranteed. Runners may find it a rewarding aspect of their sport, but the running experience is unique for each individual, and there are many reasons to run beyond chasing this euphoric state.


Some exercises that can trigger a runner's high include:

  1. Running: Prolonged or intense running is a well-known trigger for a runner's high. Endurance running, especially at a steady pace, can lead to the release of endorphins and endocannabinoids, which are associated with the sensation of euphoria.
  2. Spinning: High-intensity cycling, such as spinning, can also trigger a runner's high. Any aerobic activity that keeps your heart rate up for an extended period has the potential to induce this sensation
  3. MMA and Engaging Cardio: Engaging cardio activities that do not allow you to slow down, such as practicing mixed martial arts (MMA), can be a fun way to achieve a runner's high. The key is to engage in cardio that maintains a high level of intensity and keeps the body in motion
  4. Rowing: High-intensity rowing or other high-intensity aerobic exercises like rowing can also trigger a runner's high. These activities involve prolonged and intense physical effort, which can lead to the release of endorphins and endocannabinoids
  5. Swimming: Endurance swimming, especially at a challenging pace, can lead to the release of endorphins and the potential for experiencing a runner's high. The sustained effort and engagement of multiple muscle groups can contribute to this sensation

These exercises, when performed at a challenging and sustained intensity, have the potential to trigger the release of endorphins and endocannabinoids, leading to the sensation of a runner's high.
