Race 2 accuracy
-
@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.

@shamilt1 this will likely not change.

@Egika So unless I’m reading this wrong, Suunto either know that it measures distance a little short, but it was designed to do so…( I can’t understand why this would be the case!) or it’s not significant enough to address in an update. Personally I think it’s disappointing that it won’t be addressed.

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.

@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.
Regards
