Clearer return-to-run through data-driven rehab at Rebuild Herent

Rebuild Herent uses OnTracx to simplify and make more objective the creation of evidence-based return-to-run programs for their patients. The platform helps the team save time, improve clinical decision-making, and provide patients with clear visual feedback on their rehabilitation progress.

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. By using treadmill screening and load-based insights, the team can now guide patients more precisely while saving time and improving communication throughout rehabilitation.

Return-to-run programs available in the app and on your Garmin watch

Athletes can access their training plan in the OnTracx app and sync sessions directly to their Garmin watch, while professionals can effortlessly monitor progress and provide guidance throughout the return-to-run journey.

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.

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.

By training with OnTracx, he gained better insight into his load and focused on a smarter, more targeted approach. This helped him stay injury free, train with confidence, and achieve a breakthrough performance.

Breaking the injury cycle: Sofie’s comeback story

After years of recurring injuries, Sofie struggled to rebuild her running without setbacks. By using OnTracx alongside guidance from her physiotherapist, she gained clear insights into her biomechanical load and followed a structured, gradual progression. This allowed her to train with confidence, avoid overloading, and finally return to running without falling back into the same frustrating cycle.

Launch your return-to-run programs with OnTracx

OnTracx Platform now features the fully integrated Return-to-Run Program Generator, letting professionals create personalized, load-based plans to guide athletes back to running.

Your runs, synced with Strava

OnTracx’s Strava integration keeps your training data complete by capturing and analyzing every run, even without a sensor or phone. Missing data is automatically filled with smart load estimations, ensuring your progression stays consistent and reliable.

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!

Ghent University spin-off OnTracx raises €1.2M to help runners recover and stay injury-free

The spin-off from Ghent University raised €1.2M in seed funding from imec.istart Fund, PMV, KBC, business angels, and VLAIO. Since launching in April 2024, it has sold over 500 sensors, partnered with 20 sports medical centers, and will use the funding to enhance its product and expand internationally by helping every runner stay injury-free.

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. A high number of these injuries could be avoided with the right training adjustments using wearable technology for an individualized approach to load management. In this article, we’ll break down common training errors, their impact, and how to prevent them.
