OHR accuracy while running

Henning Hefner

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.

@Henning-Hefner I came here to report the same

Worst OHR I have ever had, worst than Race 1

4 runs
First two were recovery runs I noticed 170 during first km then 140, then again 160 …

Third one was 18k 600D fartlek trail, push hard in ascent, recovering in descent, good speed on flat sections. Hr was often 170 in recovery descent till the end, and ascent were 160… despite pushing 100%. Flat 165…

So the 4th run this evening, flat recovery run at 5:35 per km, 10km. Same as you always 165/170. Stopping twice hoping to fix that… hr went down from 170 to 120 in 10 seconds. No way mine could do that.
So finishing those 10 slow km with intense hr, I switch to polar HR and went out for another 1km for testing … same pace, perfect 138 HR in cruising mode

That Race 2 got a serious problem for some of us. It s far worst than race 1 which was already my worst ohr in 10 years. I must say epix pro gen 2 was spot on regarding HR for me.

I hope suunto is aware and working on a soft fix
