Race 2 accuracy
-
@shamilt1 I’m seeing the same shortening of distances with the updated software, possibly even slightly more (definitely not less shortening).
-
-
@EzioAuditore I am not aware, that anything has been changed in the distance measurement with the recent update.
And I have also seen the Race 2 measuring less than Vertical 2. Just I have not made a bug from this, as I am not sure, it is one. A slightly less distance does not affect me in a negative way. Plus it is not clear, if less is actually wrong…t6, S6, Elementum Terra, Ambit 3 Sapphire, Spartan Ultra Copper, Traverse Alpha, S7 Graphite LE, S9B Ambassador, S9P Titanium, S9PP Titanium, Vertical All Black, Race Titanium Charcoal, Race S Titanium Courtney, Run Lime, Race 2, Vertical 2 Titanium

@Egika I agree. However there are times that the distance is on the ‘bigger’ side. This throws away the pace and the vo2max for example. Another point that shows it is if you use snap to route or navigation, the distance shortening is less but still present. I.e.: route created via strava or SA shows 10.6 km. Running it with SV2 I get 10.55, Running it with SR2 I get 10.4
-
@Egika There seems to be an agreement on here that it under measures compared to other devices. I would have thought that would at least warrant some testing from Suunto to see if they agree.

@shamilt1 reported it

@Egika Thank you

Time ago, when I started using Race 2, I opened a thread with my tests and results comparing against Vertical and Race S.
Here is an example, if you want (and have time): https://forum.suunto.com/topic/14375/race-2-gps-cadence-and-distance-accuracy-vs-previous-suunto-models/63The behavior is always the same (and it’s replicable and easy to verify) so there’s something different in Race 2 in comparison to other Suunto watches. I don’t know if it’s better or worse but different for sure.

@jjpaz thank you! I added your information

@Egika adding my N of one, I also find it measures consistently different from every other watched I’ve used (a few from COROS, Garmin, and other Suunto watches, the Vertical 2, Race S, and Race). More telling, though, is those other watches all measure very close to my measuring wheel. The Race 2 measures shorter than my wheel, so in my experience, the Race 2 does indeed measure short. Thanks for your help on this!

@egika Yesterday I tried Race 2 with the new software and the behavior is the same regarding distances and paces as previous software:
Left: raw GPS distance showed (10.17km).
Right: postprocessed final distance showed (10.01km).First one is the GPS data recorded distance (similar to the recorded by other devices and the “corrected distance” by Strava for example. Second one is the “filtered” distance saved in FIT file data and showed by the watch ((tipically the other watches would show 10.16km with the 10.17km raw distance).
First one is always similar in all the devices. Second one only differs (shortened, 1%-1.5%) in Race 2. In every activity, both running, walking or riding the bike.
So it seems Race 2 performs a different data processing than his other “brothers”.Suunto Vertical Titanium Solar, Suunto Race 2 Ti & Suunto Wing.

I was thinking this was about the titanium Race 2 because It seems you all are comparing the Race 2 titanium with the Vertical 2 titanium.
But the thing is I have the Race 2 steel and I’m seeing a little discrepancy of what I have recorded with Garmin. But my watch is very new (2 days) and I need much further testing.
There’s also something very strange with the Race 2 (at this very new moment for now). When I import a GPX track (downloaded from Garmin Connect) into Komoot to have the turn-by-turn indications while navigating with the Race 2, is like the indications are a bit later than they should (just some few seconds). When there’s a roundabout, or a turn it seems the watch pop-ups the remaining indication a bit later or even after the turn or roundabout.
I need more testing but I’m posting this because I don’t know if it can be related with the issue you are posting here. And the thing is that those tracks are working fine in Garmin and other brands.
Or perhaps does not have sense at all, but using the same track for both the Race 2 and the Vertical 2, perhaps there’s a mechanism to see if there’s any delay with the GNSS of the Race 2.
I’d be interesting if someone could test the navigation with the same track and indications with the Race 2 and the Vertical 2 to see if there are GNSS discrepancies. -
@dreamer_ Mine is the Race 2 steel version and it seems to measure short.
-
And I thought I was the only one having this issue. I compare my usual route with all my other watches which include apex 4, pace pro , pace 4, ultra 2, polar grit x2 and Suunto race 2 invariably falls short in terms of distance. Not by a lot but about 100-150m shorter for a 10km run .
-
@leafs93 I can confirm that. Same experience here.
Time to settle this with a measuring wheel.;o) -
I can add to and confirm too short distance here as well. This is near ideal view to the sky.
I get between 0,5& - 1% too short. This is measured over tracks I have ran a thousand times and confirmed with multiple various gadgets.
I’m with an R2 titanium.

I have confirmation, that Race2 indeed measures a little short, compared to other models.
cannot share more details, but the watch works as designed.t6, S6, Elementum Terra, Ambit 3 Sapphire, Spartan Ultra Copper, Traverse Alpha, S7 Graphite LE, S9B Ambassador, S9P Titanium, S9PP Titanium, Vertical All Black, Race Titanium Charcoal, Race S Titanium Courtney, Run Lime, Race 2, Vertical 2 Titanium

@Egika I’m a bit confused by this… does this mean there’s likely to be a fix or are you saying it doesn’t need fixing?

@jjpaz I have a large number of trail runs with Race2 and V2 and they are essentially identical. I can share data, several different firmware and from 45 min to 7h trail runs. I am in the US with mostly open skies. Part of the observations may depend on the environment as I believe all of you that see shorter distances with R2. However, maybe not a firmware bug but maybe design differences including antennas. I always see fewer satellites connected to R2 than V1 or V2. Could impact distance when GPS conditions are more challenging.
