Kostiantyn K.

As a UESCA-certified Ultrarunning Coach, I bridge the gap between high-performance mountain racing and the realities of modern urban life. While my coaching practice is new, my experience on the course is extensive; I have personally navigated the demands of ultra-distance racing across various terrains, completing events ranging from 50K mountain technical races to 200K road endurance challenges.

My coaching philosophy is built for the busy athlete who refuses to compromise on their goals. I specialize in training runners who live in urban environments, travel frequently for work, and struggle to balance a demanding professional life with the high training volume required for ultra-trail races. I understand the unique challenge of preparing for mountain elevation and technical terrain while being surrounded by pavement, and I provide the strategic programming necessary to make it happen. I am eager to help you design a training structure that fits seamlessly into your life, ensuring you arrive at the start line feeling prepared, resilient, and ready to tackle your next ultra.

My athletic career is defined by a progression from competitive road racing to high-altitude mountain ultramarathons and self-supported endurance projects. Key accomplishments include:

UTMB Whistler 70K (2024): Successfully completed this world-class mountain course involving over 4,000m of vertical gain and technical alpine terrain.

200K Multi-Day Endurance Project (2025): Designed and executed a high-volume block covering 200K over three days (75K/75K/50K), demonstrating elite-level recovery and pacing.

Niagara Ultramarathon (2024): Finisher of the 80K distance, showcasing sustained speed and flat-course endurance.

Hamilton to Toronto 70K: Completed a successful self-supported solo run, managing all nutrition, hydration, and navigation logistics independently.

Competitive Standing: Consistently place in the Top-10 at local Ontario trail and road races in the marathon and half-marathon categories.

I compete at a high regional level within the Ontario trail circuit, with a specific focus on mountain technicality and multi-day resilience. These achievements reflect my ability to train effectively in an urban setting for some of the most demanding race environments in the world.

While ultrarunning is a sport of long-range vision, I manage it with short-range precision. Rather than a one-off workout, a "session" with me is an ongoing, data-driven cycle designed to fit into your urban lifestyle.

The Long-Range Framework
We begin by mapping out your "North Star" goal—whether that is a mountain 50K or a 200K endurance project—up to a year in advance. This ensures every mile we run has a specific purpose within your periodized macrocycle.

The Bi-Weekly Pulse
I provide athletes with customized training blocks in two-week increments. This allows us to be agile. After each workout, I analyze your post-run feedback, heart rate data, and recovery metrics. If work travel or city stress spikes your fatigue, we adjust the next 14 days immediately. This ensures you are consistently applying enough stimulus to progress without crossing the line into overtraining.

Even within a long-range plan, individual runs focus on three pillars:
1. Technical Specificity: Drills to simulate mountain technicality and "vert" within an urban setting.
2. Metabolic Efficiency: Specific RPE efforts/total distance to optimize how your body uses fuel.
3. Structural Resilience: Targeted strength and mobility cues to ensure your joints can handle the descent of a race like UTMB Whistler.

By working in these two-week "micro-adjustments," I ensure your training meets your body’s actual recovery rate, not just a static calendar.
