WHAT’S BRAKING?

Braking is the measure of how much your speed slows down with every step. Each time your foot hits the ground, your speed drops temporarily until you push off of your foot to propel forward and pick up speed again.

A good way to think about this is to imagine yourself switching back and forth between the brakes and accelerator of a car. The initial contact your foot makes with the ground is similar to stepping on the brakes, and pushing off of your foot is like stepping on the accelerator to speed back up.

Why is it important?

Reducing your braking is important when running because the greater the change in your speed before and after each step, the more energy you waste slowing down and having to speed back up.

Often times, a high braking value is an indicator of over-striding. If you land your foot far in front of your pelvis, you hit the ground with more backward force, causing you to slow down. The bigger the deceleration, the more energy it takes for you to speed back up.

TARGET GOAL

1.30ft/s*
or lower

*Or, 0.40 m/s

Ideally, your braking value will be as low as possible for a smooth run at a constant speed. A realistic and efficient braking value is considered to be any number below 1.30 ft/s or 0.4 m/s.

Lumo Run coaching cues.

Lumo Run detects your braking during your run and provides audio coaching cues through your headphones to help you get back into your target range.
