How to attach the sensor to your leg?

The OnTracx sensor is quite easy to attach, but needs some attention. 

1. Attach the sensor to the mount
  1. Press the pins of the sensor into the mount. 








2. Attach the strap (and sensor + mount) around your leg
  1. The strap needs to be placed about 10cm above your inner ankle, on the flat part of the shin bone. 

  2. This means that the sensor should always face a little bit inwards, not outwards (see the picture below, i.e. an example of a right leg). 

  3. The sensor should always placed in the right way. This means with the logo and the text in such a way that you can read it! 







  1. Attach the strap firmly. It should however at any time feel comfortable and not hinder your running experience. 

  2. We advise to attach the strap to the leg with the most injuries (if applicable). If you didn't encounter any injuries (awesome!), it doesn't matter which leg, but stay consistent. 

  3. Before starting your run, jump a few times up and down or jog in place for a few seconds. This helps to check whether the strap stays in place effectively. 

TWO IMPORTANT MESSAGES:
It's possible that you, while running, 'kick' the sensor out of the mount. The best way to prevent this is to put your socks over the sensor. 
If you should feel any kind of discomfort, we advise you to stop running with the sensor and strap, and to contact us immediately.
