Garmin WRIST Running Dynamics – Which models will get it?
Garmin Running Dynamics are already available for a large number of Garmin watches but some of the metrics require you to wear either an RD-POD (Running Dynamics Pod) or a top-end chest strap like the Garmin HRM-PRO Plus. (or Pro, Run or TRI)
Changes Already Made to Running Dynamics
For quite some time now, it has been possible to determine CADENCE solely from your watch’s movement on your wrist as you swing your arm. If a pod or chest strap was present then that source was favoured as it’s more accurate.
Similarly calculating stride length. Distance is usually determined by GPS and the calculation to give stride length from a combination distance and cadence is a pretty simple one.
What About Running Power?
Ah. Indeed so.
Recently Garmin added Running Power calculated solely from wrist measurements to the Forerunner 255, Forerunner 955, fenix 7, epix (Gen 2), and Enduro 2. As you can see from Garmin’s table below, it must be the case that the components of Vertical Oscillation and Ground Contact Time are already calculated for wrist-based running power.
Garmin Watches That Should Get Wrist-Based Running Dynamics
The running power feature is already included in these Garmin watches and so they already have all the bits needed for the complete suite of running dynamics from the wrist:
As always, if you want more accurate information then you need to get the right sensor to measure the inputs.
Wrist-based calculation generally won’t be as accurate as calculations made from other places; one simple explanation is that you can run for short periods without swinging your arm.
However, for VO and GCT, it’s probably not worth bothering about for most people as these metrics are of limited regular use. Put another way, it’s great that Garmin add them for free to the wrist without needing to buy another sensor 😉
