I run.
I coach.
I obsess over the details.
I'm Jasper — a marathon runner and performance coach helping athletes train smarter, race faster, and stay in love with the sport.
Hi, I'm Jasper McDowell.
I've spent the last decade chasing what running can be — from track intervals to 100-mile mountain races.
​
Today I share what I've learned with runners who want more than a generic plan. I coach with the same intent I train: focused, honest, and fully invested.

PHILOSOPHY
How I coach.
I don't believe in one-size-fits-all. Your training should fit your life, your goals, and your body — not the other way around.
"Train with intent. Recover with patience. Race with everything you've got."
— My coaching mantra
I coach with honesty — real feedback, real conversations, and a plan that evolves with you week after week.
We can train in English or French.
Whichever feels most natural to you — coaching should never get lost in translation.
