The world’s most personalized return-to-run solution 

Individual, load-based programs that align biomechanical load with each runner’s tolerance.

value proposition

Because rehab doesn’t fail in the clinic, it fails between sessions.

From screening to action in one session

Most innovative piece of running technology

Treat the cause, not just the symptoms

With its scientifically backed approach, OnTracx sets a new standard in return to run.

Stay connected between sessions

Rehab continues wherever they train, while you gain clear insight into every step between sessions.

Why biomechanical load is the missing piece in return-to-run

how it works

From onboarding to personalized return-to-run programs in under 20 minutes

Step 1

Create a load tolerance profile

Understand how much load a runner can tolerate and get recommended load progression, all tailored to the individual.

Step 2

Map running load

Use the OnTracx sensor to perform load screenings on treadmill or in the field. Map load at an individual level (Pro package) or leverage general load patterns from our complete sensor dataset.

Step 3

Generate a personalized program

Create a return-to-run plan that gradually increases cumulative load while aligning with each runner’s tolerance, and easily share it with your athlete via a unique weblink or PDF.

Step 4

Monitor progress and adjust

The free athlete app records every session, translates it into load, and sends actionable insights back to your OnTracx platform.

>80%

What rehab experts say about OnTracx

At All In, we also monitor what happens once runners go back outside. Runners often increase distance or speed on their own, which quickly raises cumulative load and increases the risk of relapse.

“It helps us guide patients returning from overuse injuries by tracking their load, pain, and effort. Combined with our lactate testing, we can now monitor biomechanical load, fine-tune training plans, and prepare every athlete even better for their goals.”
“OnTracx allows me to gradually increase the load my clients experience, in a valid and evidence-based manner. By monitoring mechanical load in combination with pain and comfort experienced by the patient, it allows me to provide better follow-up during the return-to-run process in a very time efficient manner.”
