Suunto Vertical Overstating distance
-
I ran a 47km race and my SV recorded 51.87 km. I used it with Stryd and COROS HR band. There were some sections which were extremely slow as we were held up in a technical downclimb in which we had to use a rope to descend. I have checked the readings of people with same watch and were around the 48km mark max. I am not sure if there is something wrong with the watch… elevation reading was spot on!
I understand that there might be sections where the GPS might have freaked out I.e. between trees, gorges, etc but 5km extra seems a lot… I used custom mode for gps.
On shorter runs/races readings were pretty good… it was my first long run/race with this watch so wondering if it’s one of or I am doing something wrong…
Thank you all

@Zalupas Check the map for any GPS issues. What is someone supposed to answer without any details?
-
@Zalupas You used it with Stryd? As a footpod? Then most likely Stryd is the issue (like always on my side) with huge pace / distance errors.
-
@Zalupas which custom mode did you use for GPS ? on the Vertical, unless you are in “high performance” GPS mode, you won’t have dual band enabled, which is why the signal was bad under trees or gorge.
In “high GPS performance” the battery life is estimated to 65 hours, for a 50km race i don’t understand why you wouldn’t select it ?
-
@Elipsus If he is using the Stryd footpod then the distance is coming from the pod? Right?
-
@RightNow I never used a Stryd pod so I don’t know ^^
But let’s be honest, the dude didn’t really bother to answer previous questions and just created an account for this post, so I’m pretty sure we won’t hear back from him (I would love to be wrong tho) -
@RightNow That is correct unless you tell the watch not to do that.
-
@maszop nothing strange on the map…
-
@RightNow could be the issue but I had no issues on shorter runs… I will run my next ultra without Stryd
-
@Elipsus do you refer to battery mode? I used custom. By high performance you mean the mode performance? I will try performance next time but I think I read that custom is pretty much the same
-
@Elipsus sorry for not replying early I thought my post never went through as never got a notification it had done it! Then I could not reply until I found out that my email hadn’t been verified so did not know how to answer until a friend of mine explained me why last week… apologies did not want to waste your time guys!
And yeah I will check with no stryd in my next ultra!
-
@Brad_Olwin how do I tell the watch not to do so as I am interested in seeing my power but don’t want to mess up my distance…. Thank you!

@Zalupas Yes battery modes
You seemed to be on rough terrains, so probably either lot of tree cover or steep mountain sides, which is no bueno for GPS signal as it has a tendency to either get absorbed by trees or bounce on hard vertical surfaces, so the signal get really bad.
Fortunately, the Vertical has dual band GPS, which allows it to use two GPS frequency at the same time, which is great for signal strengh and excellent for challenging environnements.I don’t know what you customized in your custom mode, so i can’t tell if you had dual band enabled, but i know that the “performance” preset uses dual band, so i would suggest to stick to it unless you go for 200 km ultras.
Side note, the very last update (from a few days ago) did also slightly improve distance calculation

@Elipsus noted! Will try this! Thanks!
