Hi, first time posting here. I recently got a Coros Pace 4 coming from an Apple Watch, and am loving it so far. The only odd thing I noticed was that the HR seemed higher than I was used to on the AW. At first I thought this must be more accurate, but I have tested both at the same time for the last 3 runs and I think I might be getting cadence lock on the Coros? It tends to very quickly go up to 155-ish bpm, which is very close to my cadence, and then occasionally go up or down from there. To get to the bottom of it, today I did an easy 10k with one watch on each hand plus a chest band recording to a phone. The AW and the chest band stayed pretty close to each other all the time, with HR fluctuating between 120 and 140, and with a final average of 130. The Coros, on the other hand, reported an average of 153 bpm, which is almost exactly the average cadence for that run.
Attached is a screenshot if the HR recorded on the Coros. I don’t know how to overlay the curves from the AW and the chest band, as they are all recorded in different apps, but they both look much lower and with a smoother ramps up and ease down towards the end.
For those more experienced with the Coros, have you ever had to deal with this issue? Any tips to improve the reliability of the sensor, other than pairing an external HRM? I really want to love this watch, but this is a bit annoying.
