Suunto ascension and Strava elevation gain
I am the new owner of a Suunto 5 and I have already done some mountain bike trainings that I synchronized with Strava, and I am amazed by the discrepancies between the ascension value in Suunto and the elevation gain of Strava …
For example: 722 m in Suunto, 1163 m in Strava !!!
I have already read that Strava recalculated the elevation, but a difference in these proportions is really amazing …
And another question, I don’t see the ascension graph on my watch, normal?
Thanks for your help.
@brnfox S5 had no barometer, and Strava elevation is based on maps. If we add that your workout is not in well-known based map (because you did some MTB) so differences could be big!
I have read that S5 elevation is very accurate (could be because has external antenna). My Spartan Sport doesn’t have altimeter/barometer (neither external antenna) and my elevation usually is less that 50% of what Strava/runnalyze says…
I will create a bug about this. S9 also has no barometer but it sends the correct elavation.
We just need to communicate this with strava
@Dimitrios-Kanellopoulos Thanks for your help!
On the same subject, I went on a trek today: Lowest point 843 m, Altitude max 1125 m -> Ascension 219 m instead of, at least 282 m, if I’m not mistaken ???
Strava 322m and Relive 339 m seem more accurate…
AND I have the altitude graph for hiking and not for the mountain biking, why?
@brnfox for the mountain biking I think it’s a know bug to be fixed on the next update.
regarding those values I can explain why (and its something that will change as research and testing is done at the moment.
The S5 due to not having a barometer, it counts ascent if you climb more than 7 meters.
This is somthing that will change.
However it records all altitude data.
So other services like strava and relive they can remove that 7m filter and then they do their own filtering and maths giving a different ascent.
I am sure Strava will always give more and might be more true to be honest. But hold on this is going to change as I mentioned before.
Thank you very much for your reply !!! Quick and clear !!! A release date for these fixes ?
@brnfox Not sure but I imagine either 2 releases on this fall or 1. Not sure yet and I really dont now
@Dimitrios-Kanellopoulos can this filter be removed for sport like cycling? I don’t see any need for this in some sports…
@nseslija we are doing R&D on this subject
