Joost discovered that fitness gains and load capacity don’t always progress at the same pace, making volume and pace alone an incomplete guide for training decisions. With OnTracx, he learned to look beyond the numbers on his training plan and make more informed decisions based on mechanical load and how his body actually feels.

ACL rehab with OnTracx

ACL reconstruction is one of the most studied injuries in sports medicine, and almost always labeled "acute": one bad landing, one wrong twist. But growing evidence suggests the story is more gradual than that, with real implications for how running is reintroduced during rehab.

Case Study SPOR Mechelen

A recreational runner with a medial tibial stress reaction successfully returned to running through an individualized Return-to-Run program, using OnTracx to identify a low-impact starting speed and guide progression based on mechanical load rather than distance alone.

Biomechanical Load: why fitness alone doesn't keep you injury-free

Biomechanical load is more than fitness alone, it plays a crucial role in injury prevention for runners. Drawing on the insights of sports physician Dr. Tom Teulingkx, it highlights the importance of gradually building load capacity and how wearable technology may help monitor mechanical stress during trainin

A Fresh UX/UI for the OnTracx Professional Platform

The OnTracx Professional Platform has been completely redesigned with a fresh UX/UI to make screening, athlete follow-up and training plan creation faster, more intuitive and seamlessly connected. With a centralized athlete view,professionals can spend less time navigating the platform and more time delivering personalized care.

Build capacity vs Manage load

Most runners think injury prevention is mainly about becoming stronger. Stronger muscles, stronger tendons, better efficiency, and so on. And while all of that matters, it only tells half the story.

Screen and support your athletes anywhere with the OnTracx app on tablet

OnTracx is now available on tablets, allowing coaches and physios to access the full dashboard, run screenings, manage plans, and follow up with athletes directly from the field.

Case Study Rebuild Herent

In this case the patient developed recurrent Iliotibial Band Syndrome (ITBS) after a half marathon, with symptoms repeatedly returning due to premature return-to-running attempts that exceeded tissue capacity. A structured return-to-run program combined with strength training and gait retraining (increased cadence and reduced cross-over gait) successfully improved running tolerance while keeping symptoms well controlled.

How SPOR Mechelen replaced guesswork with data-driven return-to-run guidance

SPOR Mechelen integrated OnTracx into its rehabilitation and return-to-run process to create more objective and individualized running programs for endurance athletes.

Which insights do you get from an OnTracx load screening & how do you use them?

Return-to-sport is often treated as a clear endpoint, but in reality it is a continuum where load accumulates across phases. The challenge is consistent load management as athletes transition back into real sport demands.

Golazo integrates OnTracx into its daily running practice to take biomechanical load into account during training progression.

Load management in return-to-sport: why continuity matters more than criteria

Return-to-sport is often treated as a clear endpoint, but in reality it is a continuum where load accumulates across phases. The challenge is consistent load management as athletes transition back into real sport demands.

Why runners don't get injured during rehab but after

Runners rarely get reinjured during rehab because load is carefully controlled, but once discharged, volume spikes, supervision drops, and strength work stops — all while tissue adaptation is still incomplete. Closing that gap requires extending structured load management into real-world running, not just the clinic.

New updates allow a smoother OnTracx experience for runners and professionals

OnTracx now includes flexible planned vs. executed session matching, and a volatile lab mode that automatically clears sensor memory after screenings, while runners get a new web dashboard and improved Garmin/Strava connectivity.

How All In turns load data into individualized return-to-run programs

"For me as a clinician, this not only saves time. It gives me much greater confidence that each runner is progressing safely, following the right program, and reducing the chance of setbacks during the return-to-run phase.”

Which runners benefit most from OnTracx?

Runners move through different phases. Some are just starting out, others are making a comeback after an injury and some are pushing close to their limits. Despite these differences, every runner faces the same fundamental challenge: understanding how their body responds to running load and learning how to progress within their individual limits.

Physiological vs mechanical load: why both matter in running rehab

Runners often get injured because their bodies can’t adapt mechanically as fast as physiologically. While the cardiovascular system may feel ready, tendons, bones, and joints often lag behind. This blog explains why measuring mechanical load, alongside physiological data, helps guide safe, individualized training.

What's broken in return-to-run?

Most running injuries develop gradually when training outpaces the body’s ability to adapt. While rehab restores function and builds load tolerance, nearly half of runners remain stuck in the injury–rehab–relapse cycle. OnTracx supports breaking this cycle with smarter load management for safe return to run.

How running speed shapes your biomechanical load

Every stride tells a story and when you pick up the pace, that story changes. Every runner has a unique relationship between speed and load, shaped by their biomechanics. Understanding that curve can transform how you train, recover, and return from injury. Read the full blog post to learn how running speed shapes your biomechanical load!

When does a single running session raise injury risk? Evidence from 5.200 runners.

Many runners like to schedule a very long run just before a big event to build confidence. But research shows that even one session can significantly increase your risk of injury, and with it, the risk of missing your running event. In a recent study of 5,200 runners, researchers identified key patterns showing how sudden spikes in training load are strongly linked to higher injury risk. Discover what the data reveals & how to recognize and avoid these load spikes so you can train with confidence, without breaking you down.

High cushioning in running shoes isn’t always the answer to injuries. Selecting shoes based on load data can mitigate your injury risk.

Mechanical overloading is a leading cause of overuse injuries, making it essential to consider the impact load associated with different footwear when selecting running shoes. We evaluated this in different runners and found that each runner had a different shoe that resulted in the lowest measured load. These findings underscore the value of incorporating objective load measurements to identify the shoe that offers the most appropriate biomechanical fit.

Breakdown of common training errors that may lead to running injuries and how to prevent them

Up to 79% of runners get injured at some point, often due to training errors.
