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.
Arun J PillaiWhy 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.

Evidence-based endurance coaching: aerobic development, threshold work, periodised training blocks and tapering.
Certified kettlebell coach
Posterior-chain loading, hip drive and single-leg stability to protect knees, Achilles and IT band.
Nutritionist
Everyday eating, race fuelling and hydration for training in Chennai heat and humidity.
Strength & conditioning coach
Strength, power and conditioning programmes built for runners, so you get faster and stay injury-free.
Masters in Yoga
A master's-level grounding in yoga science, applied to runners' recovery and mobility.

A week in the life of squad & coach
Monday: strength & mobility
After the weekend's longer run, Monday is about strength. Dynamic warm-up and drills, then runner-specific strength and kettlebell work, finishing with a breath-led cool-down.
Strength days are what let you keep running week after week.
Tuesday: easy aerobic run
Conversational pace in Zone 2. The run that builds your engine without tiring you out. Beginners do walk-run intervals.
Wednesday: run quality
Drills, then the week's key session: intervals, tempo or hills, each runner at their own zone and pace.
Thursday: rest or yogic recovery
Full rest or a gentle mobility and pranayama flow. This is where the week's training turns into fitness.
Friday: strength + yoga
A strength circuit for runners, followed by breathwork and a mobility flow to set up the weekend's running.
Saturday: easy run + strides
An easy Zone 2 run finished with a few relaxed, fast strides to keep your legs sharp.
Sunday: long run
The longest run of the week at an easy pace, practising race-day fuelling and hydration.
Sample half-marathon build week. Beginners and weight-loss athletes follow a lighter version.
The coach puts in the miles too
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.
Coach mode. Athlete mode.
