OHR accuracy of owners of Race 2
-
@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 āā6 pro was more accurate. I know that OHR canāt record sudden changes in pace, but at the same pace it measures 20-30 beats more. I really donāt understand this and Iām afraid itās 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 Iām angry that I canāt rely on the watch. I donāt feel like wearing a chest strap for 100kmā¦

@jsmno Unfortunatly Downhill the watches OHR have problems with ācadence lockā because it believes the movements are your heartbeatā¦
But as far as I know all manufacturers have this problem, interesting to hear that Garmin seems to be better in this aspect -
@VoiGAS there is absolutaly no doubt that garmin since fenix 6 has good ohr. Tested race 2 for few more runs this week, even shaving the skin, measures still a total disaster.

@Matteiva I also shave māy wrist ,
but the result was not effective. -
@jsmno OHR on any watch for me is problematic. Iāve tried most of them. Because ZoneSense is so useful I use the Suunto belt most of the time and when running ultra races. I think OHR is highly variable based on individuals because of the underlying technology.

@Brad_Olwin fully agree, OHR for me is always spot on with Vertical 1 with the velcro-band and a quite tight fit.

3 days now with Race 2. OHR seems very accurate in 24x7, walking and a 30 minute Zwift ride today.

I am starting to think that some Race 2 got OHR problems, software or hardware ?
I ran a first and perfect 10k with a fresh new Vertical 2, spot on from start to finish, with the same nylon stretch band than Race 2, same individual.
For reminder, for me with this Race 2
8k 5:35mn/km 160 average most often 165/170
Then
8k 4:43mn/km 138 average with some 120 at 4:00mn/k -
Here is comparison of Suunto 5 (with Suunto Smart Sensor) vs Suunto Race 2 (OHR). I had Race 2 tight enough but still comfortible. It is possible to tighten it one hole more but than it is not comfortable to wear anymore.
