Heart Rate problems Strava / Apple Watch 6

[gmangadsby]

Hi, I have a long standing problem which I've tweeted Strava support about but had nothing back.  I have Apple Watch Series 6, latest watch OS, iOS installed.  When I start an outdoor run on the watch's strava app, the heartrate recorded starts very high (circa 170bpm) before normalising back down to my proper heart rate after approx. 5 minutes.  My resting heart rate is 45bpm and around 60bpm when I'm walking around, so I know that a starting heart rate of 170bpm isn't real! (When the watch has normalised my max. is 140 bpm or thereabouts).  Interestingly this only happens on Outdoor Runs, if I do an Outdoor ride or another activity, the heart rate is fine throughout.  Has anyone else had this problem?

Hello @gmangadsby 

Thanks for posting about this and sorry to hear about the issue you're having.

Apple has a couple of support articles I would encourage you to check out, where they discuss how to get the most accurate heart rate measurements with Apple Watch. 

Article 1

Article 2

In particular, I would double check that the "Wrist Detection" is set to on.  

Please let us know if that helps.

Still can’t seem to figure it out
