Katarina Dimaria

Health & Fitness Coach

Katarina Dimaria-Viggers is a personal trainer, marathoner, ultramarathoner, community builder and mental health advocate based in Sarnia, Ontario, Canada. With over a decade of experience in the fitness industry, she is the owner and operator of Vibe Training for Life, where she helps individuals build strength, confidence and a sustainable relationship with movement.

An endurance athlete with six marathons, multiple half marathons and ultradistance trail races behind her, Katarina approaches running as more than a physical pursuit. Having discovered running during a particularly difficult chapter of her own life, she found in it a profound outlet for resilience, perspective and mental well-being. That experience continues to shape her work and advocacy.

She is also the founder of Everyone Run Club, a community built on inclusivity, connection and the belief that movement belongs to everyone, regardless of pace, experience or ability. Her initiatives extend beyond fitness, creating opportunities for meaningful conversations, collective support and greater awareness surrounding mental health and addiction.

In November 2026, she undertook Hellbent for Hope, a personal 100-kilometre endurance challenge in honour of her late father, raising funds and awareness for mental health and addiction support through CMHA Lambton Kent. Whether through coaching, endurance sport or community initiatives, Katarina is driven by a common philosophy: movement can change lives, connection can change perspectives, and strength is measured by far more than what we can accomplish physically. Her mission is to make people feel seen, create spaces where they belong and turn personal purpose into something that reaches beyond themselves.
