The PR Number.
Backed by science. Powered by data.
Designed for every athlete.
Fair. Adaptive. Globally relevant.
A universal performance rating system, built to
simplify the complexity of endurance sports metrics
into a single, dynamic number.
The PR# is the result of extensive research in sports science,
exercise physiology, and data analytics. Developed through
collaboration with endurance experts and grounded in peer-reviewed
studies, the PR# algorithm uses advanced mathematical modeling
to analyze a wide array of performance indicators — pace, power,
heart rate, elevation, race results, and more.
The scale ranges from 48 to 1, where 1 represents peak global performance.
Every athlete fits into this scale - regardless of age, gender or location - because we all train, we all strive and we all evolve.
What makes the PR# so powerful? It's live.
Your PR# updates in real time. It improves as you progress. It drops
when you stop. It's not just a number; it's a reflection of
your current potential, your commitment, and your continuous
journey as an endurance athlete.
