The Coach

Built on
Real Miles.

I'm Jonathan Fuller — Clinical Exercise Therapist with a BScKin and a Master of Science in Physical Therapy, and an ultra-endurance athlete who has toed the line at some of the most demanding events in North America.

I don't coach from the sidelines. I've finished the Canadian Death Race, run Iron Legs 100km, survived The Divide 200, and competed at the Lone Wolf Backyard Ultra. I know what it takes to keep moving when everything in you says stop.

My background in physiotherapy and exercise science means your training isn't just built on grit — it's built on evidence. Every plan is designed to get you to the start line healthy and to the finish line strong.

Who Cairn
Is Built For.

⛰

Trail & Ultra Runners

From your first 50km to your first 200-miler. If you're drawn to mountains, mud, and miles that most people won't attempt — you're home.

🪖

Military Athletes

Selection prep, operational fitness, or running your first ultra post-service. Training built around the demands of the job — and beyond it.

🔴

First Responders

Police, paramedics, and emergency services athletes who need a training approach that respects shift work, unpredictable schedules, and high-stakes careers.

🔥

Firefighters

Wildland and structural firefighters need sport-specific endurance and strength. We build programs that translate directly to the line.

How It Works

The Cairn
Process.

01

Apply

Fill out the inquiry form below. Tell me about your current training, your target race, and what's held you back. I take on a limited number of athletes to keep coaching quality high.

02

Discovery Call

We get on a 30-minute video call. I want to understand your history, your terrain, your lifestyle, and your why. This shapes everything in your program.

03

Custom Program Build

Your plan is built around your life — not a template. Periodized, progressive, and grounded in exercise science. Delivered through TrainingPeaks before week one begins.

04

Ongoing Coaching

We adapt week by week. Life happens. Terrain changes. Your body talks. I listen. The plan evolves so you keep progressing toward the finish line — and past it.
