Running Dynamics & Swimming Features on the 235

_hq_
I just ordered my 235, but I'm new to all of this.

While comparing features, I noticed the 235 is missing the Running Dynamics feature of the 630. The premise is that the 630 requires the HRM-Run monitor's built-in accelerometer to provide metrics such as: Stride Length (in real-time), Vertical Ratio / Oscillation [bounce], Ground Contact Time, etc.

Well, if the 235 has a built-in accelerometer (for Training Indoors), why not use that??! And if Garmin decided to omit this feature to up-sell the 630, would it be possible, at least in theory, to provide those metrics using a Connect IQ app?

Same goes for Swimming features (distance, pace, stroke count/rate), doesn't the watch posses all the hardware it needs to calculate such metrics?

Just curious...

    right fair point about what stats. But if this is all right that everything comes off the 235 itself then I guess the tell-tale sign would be to run with a non-HRM strap (just the HR only one) and see what shows up after a run. Just thought of that now. If I can find an older strap I guess I will try it out and see.


    I run with Geonaute ANT+ coded digital HRM Chest Strap which only provides HR data.
    Below is one of the run using that, am curious if Garmin HRM-Run will provide more running dynamics to 235. The two major running dynamics I am missing from mine is the Ground Contact Time and Vertical Oscillation, which can be provided by Garmin HRM-Run to compatible (or rather made compatible) devices like 920XT and F3 (and probably 6302, not sure).

    … am curious if Garmin HRM-Run will provide more running dynamics to 235.
    I think the HRM-Run does not check the paired device's make and model, and it's more likely that the FR23x's firmware does not implement the private ANT profile for receiving Garmin's Running Dynamics data, in which case:
    • it is not a hardware limitation on either the FR23x or the HRM-Run;
    • the HRM-Run will pair with and talk to any FR23x just fine;
    • it would therefore be technically possible to implement by a change in the firmware on the FR23x alone; and
    • there is no commercial reason or incentive for Garmin to do so this long after the FR23x models have been released to the market.

    These are the Running Dynamics metrics the FR630 is capable of handling (when received from a compatible sensor device): cadence, vertical oscillation, ground contact time, ground contact time balance, stride length, and vertical ratio.
