Teun

Sprinter on the piste, builder off it. Chasing the 100m & 200m while racing — and living — with Type 1 diabetes and an under-active thyroid. I track everything, learn out loud, and share the data so others don't have to figure it out alone.

01 About

Athlete & technologist, living with Type 1

I race the short, explosive distances in inline speed skating — where every hundredth counts — and I do it as a Type 1 diabetic. Off the track I build the systems that keep me on it: a personal AI platform that turns my glucose, lab, wearable and training data into decisions.

Power & speed

100m and 200m sprint specialist — training built around maximal output, acceleration and top-end speed.

🩸Type 1, out loud

Diagnosed in 2018. I manage blood glucose on a closed loop and weigh it against training, sleep and bloodwork — and I share what works, openly.

🔬Data-driven & self-built

Every session, lab and night of sleep feeds one model that tells me when to push and when to recover — software I engineered myself.

02 By the numbers

Open data

I train and live by my data — and I share it openly. A snapshot of where things stand right now.

03 Health journey

The road back

A timeline of the challenge and the comeback — the setbacks, the treatment, and the return to chasing performance.

06 Technological goals

Building the edge

The performance gains I'm engineering for, not just training for.

🧠One central brain

A single AI that knows everything across my local and cloud tech — delegating to controllers for life-tracking, training and more.

📈Closed-loop training

Wearable + lab + periodization data feeding recommendations that adjust my plan in real time.

🩸Athlete-optimal biomarkers

Tracking blood markers against sprint-athlete optimal ranges — not just generic reference values.

🔁Fully portable

Everything as code, movable to any machine — my data and my system stay mine.
