OHR accuracy of owners of Race 2
-
Today possibly cadence lock in first half? Not sure but strange change in middle of activity while i walked same speed all the way.

-
@Adam.B which Garmin are we speaking of?
-
Today I did bike ride, almost all it was done on asphalt road. Here is comparison of Suunto 5 (using Suunto Smart Heart Rate Belt), and Suunto Race 2 OHR sensor.

Yesterday during a long run. Constant pace all the way.

Ok so I am not alone with those crazy high bpm in the beginning of each easy run… -

@sorinus try to wait minute or two after watch lock on HR before starting your excercise.
-
@Tomas5 with almost every Suunto watch I had bad OHR readings when riding my bike.
Usually it would eventually just fall into the lower 80s and stay there.Race 2 was the first watch to ever got OHR in cycling right for me!

-
@Tomas5 Mine is 100% off… See my report https://forum.suunto.com/post/177055
With screen capture, same evening first 10k easy with suunto ohr 165/170…
Then another last km with polar chest just to confirm I was not crazy or hill
Same pace in both case 5:35 per km

@Matteiva my test from bike ride turned out good. Comparing to chest strap. I will do similar for walking activities. I am suspiciouse there is possible cadence lock when watch is not tight on your wrist. But i will see after comparison with chest strap. Hope i will find time to test this week.

With old Suunto 5 i hade from time to time crazy high HR measurement using OHR sensor. At least this didn’t occured yet on Race 2. So big improvement in that for my.

@Tomas5
in 10 years that’s the worst OHR I have ever seen for me while runningchest are always the best for specific workout, but for daily training or trail a good OHR should be enough, I use both chest and ohr, but very disappointed with the race 2, meaning I can not train with it’s ohr

-
@Matteiva I’ve been having a few problems with my Race 2, but OHR isn’t one of them — it’s actually been quite good, to be fair. Much better than my previous Coros Pace 3.
Today I did a 45-minute workout: 5 minutes in zone 1, 30 minutes in zone 2, and 10 minutes in zones 4 and 5. The watch performed impeccably in terms of OHR accuracy, as you can see here
-
@Matteiva hey, I am curious. Which OHR did you use 10 years ago? Must have been one of the first gadgets.
-
@Gunnar Tomtom watch, maybe not 10 but 8
ohr was better 
-
@gogapo it surely depends per individual, skin tone, pilosity, and veins
I always used same strong nylon scratch band since garmin fenix 6x
-
@Matteiva I just read a review of the Tomtom runner 3. Same user experience as today for current watches. Nothing changed apparently

-
@Gunnar
yes I remember it was almost 10 bits above my real heart rate, but race 2 was 25/30 yesterday evening, during all my activity 
And garmin epix pro 2 was spot on most of the time, same type of band same personn ( me ! )
Hoping a fix soon

Hi everyone. I am new to this forum. And I am the owner of my first Suunto device.
I really like the Race 2. They have a nice weight, a nice large display, and easy control with the digital crown.
What I am disappointed with is the quality of the OHR measurement. Today I had a light running workout in zone 1-2 during which I can breathe through my nose easily. From the chest strap I know that at this pace my heart rate is around 130-140. I ran downhill and my heart rate was 164-172. This is the heart rate I get during interval training!
I feel like my old Garmin Fenix 6 pro was more accurate. I know that OHR can’t record sudden changes in pace, but at the same pace it measures 20-30 beats more. I really don’t understand this and I’m afraid it’s more of a hardware issue than a software one.
I have white skin. Original suunto textile strap. Tight enough.I have an ultramarathon coming up this weekend and I’m angry that I can’t rely on the watch. I don’t feel like wearing a chest strap for 100km…

@jsmno Unfortunatly Downhill the watches OHR have problems with “cadence lock” because it believes the movements are your heartbeat…
But as far as I know all manufacturers have this problem, interesting to hear that Garmin seems to be better in this aspect
