The origin

Why I coach

I didn't discover running as an adult. I grew up as an athlete. From a young age I was competing in the 800m and 1500m at school, representing my school at district-level competitions and winning a few races along the way. Athletics was a big part of my childhood, but when I reached 12th standard I had to step away from sport to focus on academics. After college I got into motorcycle racing, which eventually brought me back to fitness through running, cycling and swimming.

Around 2018 I found my way back to running, but this time I wanted to understand it beyond just running hard. I became fascinated by running form, training, recovery and the science behind performance. The more I learned and applied to my own training, the more I fell in love with the process. Running slowly became more than a sport or a way to stay fit. It became something I wanted to truly understand.

That curiosity eventually led me to coaching. I wanted to share what I had learned, help other runners improve, and give them the kind of guidance I wish I had while figuring things out myself. I pursued running-specific education and started applying that knowledge with other athletes. Coaching has become the perfect way to combine my athletic roots, my passion for running and my desire to help people become better athletes, and to turn something I have always loved into my profession.

The dual heritage

Why scientific data alone still fails runners

Most distance coaching looks only at paces and mileage. Arun combines certified exercise science with classical yogic recovery, so the body that does the training can also absorb it.

Arun still trains every week, the same way he coaches: mostly easy running, relaxed form, quick light steps. You learn more from running beside him than from any plan on paper.
