Overview
Based in Ghent, OnTracx builds hardware and software for serious runners who want more than GPS tracking. The company's sensors capture biomechanical data such as cadence, ground contact time, vertical oscillation, and load metrics that are relevant for performance coaching and injury prevention.
The data is analyzed through a companion app that provides personalized insights and training recommendations. OnTracx targets competitive amateur runners, running clubs, and coaching programs that want objective data to inform training decisions.
Sports performance monitoring is a growing category as wearable sensor technology becomes more accurate and affordable, and as the running community becomes more data-driven in its approach to training.

- The same training load can feel manageable one week and like too much the next. Why? Because your body's capacity to handle load isn't fixed. And sleep is one of the factors that can influence it. One bad night won't make or break your recovery. But when poor sleep becomes a pattern, it may affect how your body responds to training load. In our latest blog, we explore what the evidence says about sleep, injury risk and recovery, and why sleep deserves a place in the bigger picture of load-based training. Curious to learn more?
- When a runner reports pain, the conversation often becomes binary: keep going or stop. Research on Achilles tendinopathy (Silbernagel et al., 2007) points to a middle ground. Runners who kept training within an agreed pain-monitoring model improved just as much as those who rested. That shifts the question from “run or rest?” to “how much?” OnTracx connects biomechanical running load with reported pain and effort after every run. That gives physios and coaches the insight to adjust the plan while a setback is still small. From
- What. A. Weekend. 🙌🏼💙 Last weekend, we brought OnTracx to Flanders Technology & Innovation Festival in Mechelen, and what a run it was! So many curious runners, screenings and insights 🏃🏼♂️ Over the weekend, runners stepped onto our treadmill to discover more about their own biomechanical running load. Each screening offered a glimpse into what makes every runner different: how much load their body experiences, how individual load and load tolerance can be, and why gradually building up towards a personal goal matters. Because
- Our student project is now live in the OnTracx app! OnTracx measures the load of every single running step with a sensor. Speed, distance, hills, surface, and cadence all play a role, but their impact differs from runner to runner. So how do you figure out what drives the load for each runner? That’s the question one of our Everest teams took on. Over 8 weeks, they worked out how to build a personal load model for every runner. Today, that model is live in the app: every runner can see which factors make their steps land harder or
