What Happens When You Start Running

When I first started running, I had no idea what to expect. I had seen others effortlessly gliding along, their bodies in perfect sync with their strides, and I wanted to experience that too. Little did I know that running would not only transform my physical fitness, but also have a profound impact on my mental and emotional well-being.

At first, my body resisted the new challenge I was subjecting it to. Every muscle ached, and every step felt like a struggle. But as I persisted, something amazing happened. My body started to adapt. My cardiovascular system became more efficient, allowing me to go farther and longer without feeling exhausted. My muscles grew stronger and leaner, giving me a newfound sense of strength and endurance.

The benefits of running extend far beyond the physical realm. It has become my ultimate stress reliever, a time when I can escape the demands of daily life and focus solely on the rhythm of my feet hitting the pavement. The endorphins released during a run flood my body, creating a natural high that leaves me feeling euphoric and energized.

But running isn’t just about the physical and mental transformations. It has also opened up a world of exploration for me. I have discovered new routes and trails in my neighborhood, each one offering a different challenge and scenery. Whether it’s a peaceful park or a bustling city street, running has allowed me to intimately connect with my surroundings in a way that no other activity can.

The Science Behind Starting to Run

When you start running, your body undergoes several changes to meet the demands of this new activity. One of the most noticeable changes is an increase in your heart rate. As your body starts to exert more effort, your heart pumps more blood to your muscles, delivering oxygen and nutrients while removing waste products.

Your lungs also adapt to running by becoming more efficient at taking in oxygen and expelling carbon dioxide. As you run more frequently, the number of tiny air sacs in your lungs, called alveoli, increases. This allows for greater gas exchange, resulting in improved endurance and stamina.

Another important adaptation that occurs when you start running is the development of stronger muscles and bones. Running is a weight-bearing exercise, which means it places stress on your bones and muscles. Over time, this stress stimulates the production of new bone tissue, making your bones denser and less prone to fractures. Similarly, your muscles become stronger and more efficient at generating power, which improves your overall running performance.

The Mental and Emotional Benefits of Running

While the physical benefits of running are undeniable, the mental and emotional benefits are equally significant. Running is a natural antidepressant, thanks to the release of endorphins during exercise. These feel-good chemicals not only elevate your mood, but also help reduce stress and anxiety.

Additionally, running can improve your cognitive function. Studies have shown that regular aerobic exercise, such as running, can enhance memory, attention, and problem-solving skills. The increased blood flow to the brain during exercise promotes the growth of new neurons and improves overall brain health.

Running also provides a sense of accomplishment and boosts self-confidence. Setting and achieving running goals, whether it’s increasing your mileage or completing a race, can instill a sense of pride and empowerment. The discipline and dedication required to stick to a running routine can carry over into other areas of life, fostering a positive mindset and a belief in one’s abilities.


Starting to run can be a transformative experience, both physically and mentally. The changes that occur in your body as you become a runner are truly remarkable. From increased cardiovascular fitness to stronger muscles and bones, running has the power to change you from the inside out.

But it doesn’t stop there. Running also provides an escape, a chance to connect with nature and explore new paths. It has the ability to improve your mood, reduce stress, and enhance cognitive function. And perhaps most importantly, it fosters a sense of accomplishment and self-confidence that carries into all aspects of life.

So lace up your running shoes and take that first step. The journey may be challenging at times, but the rewards are immeasurable. Trust me, I’ve been there, and I can confidently say that running has changed my life for the better.
