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.

- ACL reconstruction is almost always framed as an acute injury: one bad landing, one wrong twist. But what if the injury starts long before that final moment? 🤔 Growing evidence suggests it may, with important implications for return-to-run after ACL reconstruction. Once an athlete is cleared to run, the next question becomes: how should running load be built up safely over time? That's where objective load monitoring can add another layer to clinical decision-making. See how OnTracx supports return-to-run after ACL reconstruction
- Getting stronger isn't enough to prevent running injuries. 👊🏼 Most injuries happen when training load exceeds what your tissues can tolerate and not because you're not strong enough. The challenge? Your fitness improves much faster than your tendons and bones adapt.That's why injury prevention isn't just about building capacity. It's about managing load. Read our blog on our website about capacity and load management to learn why both matter. 🔗 How do you currently manage your training load? 🤔

- He completed his first half marathon. A few months later, he couldn’t run 2 km without lateral knee pain. Every comeback attempt followed the same pattern: → Start running → Increase too quickly → Pain returns Testing showed he could run at higher speeds without symptoms — but his tissues weren’t ready for the repeated mechanical load of running. With OnTracx insights, cadence adjustments, strength training, and a gradual return-to-run plan, Rebuild Herent focused on rebuilding capacity step by step. Key takeaway: Overuse symptoms
- This one's for every runner, coach, and physio out there! 🔈 We're excited that Bonnaerens Senne, co-founder of OnTracx, was invited by Tom Teulingkx and Marc Geenen as a guest on the podcast Biefstuk in de broek. 🎙️ Senne holds a Master's degree in Movement and Sports Sciences from Ghent University and completed not one but two PhDs, in Biomechanics of Human Locomotion and Musculoskeletal Modelling. Safe to say, he knows exactly what he's talking about. 🧠 Hit the play button if you've ever wondered: 👉 How much load does running
- Making return-to-run guidance more objective, efficient, and easier to understand. Here's what Jolien, Owner & Physiotherapist at Rebuild Herent, had to say about OnTracx: 💬 "With OnTracx, we can now analyze running load much more concretely and automatically create evidence-based training schedules. That saves us time, but also makes things much clearer for the patient. Thanks to the visualizations, athletes better understand where they are in their rehabilitation journey and how they can safely progress." We're proud to
- You finished rehab. Pain gone. Ready to run. ✅ And yet — 50 to 70% of runners get injured again within a year. Sounds familiar? During rehab, everything goes well. Strength builds, tissues heal, pain disappears. But the moment you're back on your own, training load jumps up faster than your body can handle. Tissues adapt slowly. That mismatch is what causes most relapses. Not bad luck or weak muscles. Just too much, too soon. 📈 An important & often missing piece of the puzzle: gradually increasing load over time, tailored to
