FOUNDER & HEAD COACH
TOM FOKKENS-ANCERY
I entered the world of endurance sports with a Black Belt, multiple national titles in TaeKwon-Do, and a silver medal at the European Championships. I knew how to train at an elite level.
But when I transitioned to triathlon fifteen years ago, I hit a wall. Not a physical one. An architectural one.
I followed the "proven" plans. I hired the "expert" coaches. I chased the "perfect" data points. The result? I trained harder, got fitter, and raced worse. My injuries were treated as inevitable, my long-term growth was ignored, and my technique was sacrificed for empty volume.
Sense Endurance Coaching was built to kill that cycle.
THE BLUEPRINT
// DURABILITY OVER VOLUME
We build engines that don’t break under pressure. Volume is a byproduct; durability is the goal.
// CONTROLLED INTENSITY
Total physiological intent. We eliminate the "Gray Zone" to ensure every mile drives a specific adaptation.
// BIOMECHANICS OVER VANITY METRICS
Efficiency is the ultimate performance metric. Speed is nothing without technical integrity.
// FORM UNDER FATIGUE
Technical mastery at the limit. We train to maintain composure when the heart rate is high and the fuel is low.
