Heart Rate “spikes” when pairing Coros HR armband with Run
-
I’m seeing random heart rate spiking when using my Coros HR armband
What can I do to resolve this? Or is this a bug with the Bluetooth connections for the Run Watch?
-
This is not an issue with Coros, but an issue with the Suunto run (I have the same issue with a Polar hr sensor). They admitted it when I emailed support and said they’ll look into it (that was a couple of months ago),
-
I have a Coros armband and a Coospo belt. I’m going to test whether I also have HR spikes.
-
Tested today with Coospo belt – seems fine to me : (just when starting up, but it might be because of the belt)

@zagazoo Is the firmware on your armband up to date?
-
Also having issues with the Coros Heart Rate Monitor armband with the Suunto Run.
Abnormally high spikes appear out of nowhere and certainly not in keeping with the effort/pace etc of the run. These spikes frequently jump up 20 beats in a second before falling just as quickly.
Sometimes almost the entirety of the run in terms of the heart rate graph will look fine apart from the end of the run when these spikes will just appear.
Given the fact others have reported the same with both the Coros and Polar heart rate armbands there is clearly an issue here.
Coros Heart Rate Monitor is on the latest most up-to-date firmware as is the Suunto Run.

@zagazoo I use Coros HR armband a lot with Race and Race S. I have never seen spikes like this. This may be a Run specific issue.
-
Tested today with the Coros HR armband, everything seems fine - firmware du Coros : V1.22.0

Today I ran with the Suunto Run and Coros HRM together and with my Garmin paired with a Coospo chest strap.
The graphs look very similar with some very slight differences as to be expected comparing optical with a chest strap but again the Suunto Run with the Coros HRM produced a spike not present on the other combination.
It showed a brief spike elevating my heart rate by around 20 BPM.
Tomorrow I’m going to replicate the run but with the heart rate monitors switched to see what is going on. I’ll provide some pictures after to show the issues I’ve had.
I have also noticed that even when using a chest strap with the Suunto Run that the heart rate graph on the app and the summary values provided for Max Heart Rate are not always the same. The graph might show a max heart rate around 174 for example but the information provided in the Heart rate section along with the Physiology and Power may provide a max HR of 190.

@ruNSuunto I cannot find the peaks with the same type of equipment as you.
Can you check the firmware numbers of your equipment: Suunto Run and Coros Heart Rate Monitor?
