I’m a passionate endurance and ultradistance runner, coach, and lifelong student of the sport. My journey began with a single 5K and grew into a passion for longer challenges. I’ve completed 34 marathons and 40 ultramarathons, including distances up to 120 km. A Chemical Engineer by profession, I specialized as a running coach to share my experience and knowledge. Through Running Army, I help runners train smarter, build confidence, and discover how far they can go.
I believe that every runner is different, and there is no one-size-fits-all approach to training. My coaching philosophy is built around consistency, individualized training, and long-term development. I focus on helping athletes understand the purpose behind their training, listen to their bodies, and build the physical and mental resilience needed to reach their goals.
Whether the goal is a first 5K or an ultramarathon, I believe progress comes from smart training, patience, and consistency—not shortcuts. My role as a coach is to provide guidance, structure, and support while helping each athlete gain confidence and discover what they are truly capable of achieving.
