Race 2 accuracy

Suunto either know that it measures distance a little short
It measures shorter than the other models. The question is is it more accurate, though?

@2b2bff I wrote about this before, but from my n=1 sample size, the Race 2 measures short, and is further from true distances than other watches from Suunto, COROS, and Garmin. I’ve measured it against a measuring wheel. Also, recent race performances by elites wearing the Race 2 in certified road races also have it measuring a bit shorter than race distances.

Nordic Walking on a measured loop of 2260 m:

Loop Race S Garmin 955 1 2277 m 2259 m 2 2263 m 2263 m 3 2267 m 2262 m 4 2255 m 2267 m April 19
Loop Race 2 Garmin 955 1 2244 m 2261 m 2 2241 m 2263 m 3 2244 m 2267 m 4 2242 m 2272 m 5 2238 m 2265 m On measured straight paths, errors were smaller.

@2b2bff I don’t think so…surely all the other devices can’t be wrong?
Additionally, when I plot a route on footpath or the Suunto app, the Race 2 always returns a shorter distance than the plotted route too…my other watches don’t. This is mainly on canal towpaths so not a lot of cutting corners going on…but plenty of weaving round walkers etc. that could add a few meters.
But it appears it’s not going to be looked at and I’m struggling to see why this would be.
-
@shamilt1 you cannot address it easily. You cannot add 0.5% distance to everything, because there are situations where it does not measure short.

@shamilt1 ran a marathon at the weekend and measured 45metres out (short)…which seems very decent, especially with some distance of that being spent on narrow streets with tallish buildings.
My km auto-lap buzzes were generally bang on, or up to maybe within 10-20metres when passing the course distance markers through until at least 30km…(I stopped caring/noticing beyond that!).
-
@Nigel-Taylor-0 I’d certainly settle for that over such a distance. In comparison, my last run was 14k and my Race 2 measured 90 meters shorter than my other watch, so not as good as you got.
I understand it may not be an easy fix, but let’s hope the boffins decide to take on the challenge and get it sorted…it’s the one thing that bugs me about this otherwise excellent watch. -
Hi,
To contribute to the thread, today I did a mountain bike ride with my Race 2 Titanium and a Garmin 530. The difference was only 40 meters: Race 2, 30.98km vs Garmin 530, 31.02km.

I’m commenting to myself to point out that, however, the distance after applying Strava’s distance correction increased to 31.45 km. I assume Strava performs the correction using 3D distance (taking into account the terrain’s elevation), which in this case was 840 m of positive elevation gain.
Related to this, does anyone know if this parameter can be applied to the distance calculation? I haven’t seen it on Suunto, but Garmin has the option, although it’s disabled by default.
Regards

80 km trail race here is distance from V2 and R2 well within GPS error. First V2 and second R2 with V2 right wrist and R2 left wrist. Last Saturday 18/04
Distance 85.76 Km 84.32 Km 1.44 Km (1.7%) -

Distance 85.76 Km 84.32 Km 1.44 Km (1.7%)There you have the ~1.5% difference in mountainous terrain, as I wrote in my tests thread.
The thing is that older models (Race, Vertical, Race S) will be closest to V2 distance than to R2 distance so clearly accuracy is different in Race 2.
