Do you know of any studies that measure the accuracy of the Garmin Running Dynamics sensors in either the Tri HR Monitor strap or the Running Dynamics pod?
I have seen a few comparisons against Stryd, but not against a force plate (or mat…we just a runway at work for about $20k that is long enough to collect a handful of strides, thus avoiding possible targeting issues).
It would be my guess that Garmin isn’t too far behind Stryd in figuring out the algorithm to determine run power using GCT, stride length, vertical ratio, and vertical oscillation
Garmin started reporting power 6 months or more ago. Not surprising, really, since calculation of running power is rather trivial, at least if the input data are “clean”. A bigger issue, really, is deciding what power is most relevant to calculate.
