Why load matters

Most running injuries are overuse injuries. They happen when your load exceeds what your body can handle. Safe progression isn’t about avoiding high load, it’s about balancing load and tolerance to prevent injuries and recover smarter.

You can’t manage what you don’t measure

OnTracx quantifies impact load step by step.

Using a lightweight sensor, we measure the biomechanical load your body experiences during every run. These measurements closely match gold-standard lab metrics, but now they work outdoors, in real life.

Know Your Limits, Run Smarter

Load tolerance or load capacity, indicates how prone a runner is for sustaining an injury.

OnTracx classifies runners into low, medium, or high tolerance using evidence-based factors like age, experience, injury history, and current pain.

With this insight, you can distinguish runners who need to build up load gradually and from those who can increase their load more progressively.

Personalized Programs, Smarter Running

OnTracx translates load and tolerance into individualized, load-based return-to-run programs, designed for smart and controlled progression.

From award-winning science to in-the-field technology

Built on rigorous research and real-world testing, our technology delivers reliable insights you can trust.
