      Hello,
      I am an owner of the Race 2 and I have trouble with the OHR while running (normal use is fine, bicycle is fine). Right after the start the heartbeat goes up to 170 and stays there till I stop. It is just a normal run, heartbeat should be at around 140, though. When I stop it goes right back to normal, when I start running again it goes straight up again. The graph looks a bit wild as I stopped quite often. Only in the end it came to a normal rate. I tried a tight fit and also a bit further up the arm but it all didn’t help. Next day the same.
      The rate is so way off that I’d say it is a bug. Does anyone have a similar experience?
      Again, it is only when I am running.
      Any help is appreciated.

        @Henning-Hefner Could be the cadence lock problem, where the sensor believes the movement off the watch on your wrist is interpreted as your heartrate.
        Should be better if you wear the watch tight and above your wristbone

          Thank you @VoiGAS for emphasizing the tightness once more. Looks like I have to wear it even tighter than my old Polar M430. Today it worked just fine.
