My #Garmin watch has been pushing up my auto-detected maximum heart rate for months now.

And now it says my max HR is 211! Either I'm getting more and more fit as I age (early forties now), or something is fishy. Since my workouts are based on my max HR, they have been also getting more difficult over time. I checked reddit and found many people complaining about this. So today, I manually set the max HR to a reasonable value.

Anyone else faced this issue? @running @garmin #running #runnersofmastodon

You can expect detected Max HR to change over time due to improved accuracy from usage, but a HR that high does seem suspect and I would assume a software issue. Real underlying MaxHR shouldn't increase significantly, and it's expected to decrease with age.

If you're not already using a heart rate strap, you should get better accuracy that way (there are also armbands that I hear are quite accurate too). In addition, Max HR based workouts are the least accurate anyway and if you use a strap, you can do lactate threshold based zones.

Firmware upgrade and/or a factory reset of the watch may help the actual problem with the detected MaxHR, though.
