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.
