        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.

              The crazy high BPM at the beginning of an easy run is since forever on my Vertical too.

                @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! 🙂

                      @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 running

                          chest 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.

                                  @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
