Welcome to The Scientist’s Notebook

The Scientist’s Notebook is a passion project launched in December 2025 by me, Dr. Thomas Mortelmans. It’s a space where my two worlds—biomedical science and endurance cycling—finally meet.

I created this publication for those of us who love the data but live for the ride. My mission is to take the complex science of the human body and turn it into a friendly, actionable roadmap for your training. Whether you're a seasoned racer or just starting to find your wings on the road, I’m here to help you ride smarter and stronger.

Your Private Training Library

By joining us, you’ll unlock subscribe to weekly releases of the full archive of "Field Notes"—a private library of every deep dive, training protocol, and scientific insight I’ve ever published. Think of it as your go-to resource for whenever you want to understand your body better or find that extra 1% of performance.

Insights, Delivered with Care

No more battling algorithms or missing out on the good stuff. Every new entry is sent directly to your inbox like a personal letter from a friend who happens to be able to unlock your endurance potential. It’s fresh, evidence-based content delivered straight to you, so you can focus on what matters: the road ahead.

A Community of Fellow Travelers

You’re in good company here. This is a home for a global community of endurance athletes. We are a group that values inclusivity, mental resilience, and the simple joy of a shared passion.

Why Your Presence Matters

This notebook is an independent publication made possible by you. Your support allows me to keep these insights objective, honest, and personal. Thank you for being part of this journey and for allowing me to be a small part of your cycling story.

Let’s see where the next chapter takes us.
