Know your limits. Measure with load. Progress with confidence.

OnTracx turns complex biomechanics into clear, actionable insights for runners and professionals.

Understand your limits

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 pain.

This insight helps determine who should build up gradually and who can progress faster whether you’re running yourself or guiding athletes.

You can’t manage what you don’t know

OnTracx quantifies impact load step by step.

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

Progress is safest when it’s guided by data

With the OnTracx app, runners can track load and monitor their progress over time. This data syncs seamlessly with the OnTracx platform, giving professionals the tools to guide athletes individually, create load-based return-to-run programs and plan smart progression.

Together, runners and professionals can work toward safer, more efficient, and data-driven training.
