@bitcoin did you solve your problem? I had the same error on my Suunto 9 Peak Pro few days ago, now i can’t use it without constant connection to it’s charger

I usually always check if the altitude shown by the watch is correct, if not it can be set manually or auto adjusted. Apart of that, the data look very scattered, I agree with Egika about strong wind or dirty sensor. Did you get the same behavior also other times? in this case the pressure sensor could be defective.

@maszop makes sense, but I wonder why the watch stops recording/calculating its estimate of calories burned while connected to the Karoo, I don’t expect it to be in my gpx recorded in the Karoo, but I would expect the watch to sync its calories from during the activity to the app.

@matram pm me with your GitHub name, I’ll add you to my S+ skill repo. I’ve already done the digging.

@Masnyband You need to have navigation turned on for LOOP to work… another option is to use my S+ aLOOP which doesn’t require that and is more accurate at detecting your position, preventing false positives.

@2b2bff I think there may be some confusion between the standard running dynamics already available on the watch and the additional metrics provided by the Suunto Spark. The Race series can already record metrics such as cadence and some running dynamics. However, one of the new metrics provided by the Suunto Spark is Ground Contact Time Balance (left/right balance), which shows how evenly you load your left and right foot while running. As far as I know, this specific metric is currently only supported within the Suunto ecosystem when using the Suunto Run. I have not seen it being recorded or displayed in the activity summary on the Race 2 yet. So if Ground Contact Time Balance is the data you’re looking for, that may be the reason it is missing rather than a connection problem between the Race 2 and the Spark.

@2b2bff said: @stromdiddily there is no universal “This is a workout file, deal with it watch” format. If you are pushing a workout to Garmin, you define the steps. If you push the workout to Suunto, you define a SuuntoPlus Guide. I don’t know how Coros or Apple Watch does handle it. So, Training Peaks - or any other platform for that matter - has to include the respective framework for each brand individually… The other way around, if you read the finished activity from the watch, there is a format that has been widely adopted: Garmin FIT files. I see, this makes sense…thank you

Scusate ma non capisco il voto negativo!!!

@Squirrel completely agree. In fact, at this moment is very likely the Race and Race S are the only watches of the market without the white/red implementation. It’s not something critical, of course. But now everybody seems to like the flashlight in the watch, it’s one of those details that are very visible

Thank you everyone i will wait

I have the same issue. I sent watch data to Suntoo. I want to ask, does factory reset remove my own intervals?

I wanted to know if it was a normal behavior of the watch because on my side it is a problem because it turns on almost all the time the watch and so the autonomy is not there

Hi everyone, I think my problem was that I had configured the screens and synced them, but when I tried the mode without GPS, it wouldn’t start the custom views, and I only had a few bits of information. Yesterday, while sorting through my data, I got my custom displays. However, now in the Suunto app view, I have no details at all… just an error message… and the Strava sync, TrainingPeaks, tells me I only ran 6km instead of 10… Ugh… you chase one problem and another pops up. But so my original problem is solved… or at least it seems so. Thanks everyone.

@UE_Suunto Do you have touch enabled in Exercise options?

@MiniForklift I haven’t heard anybody using EPOC during a training. It is mainly mentioned in weight loss blogs. It is also questionable if a watch can determine EPOC because, besides heart rate, oxygen used must be measured. No watch can do that. So EPOC is guesstimated by the watch at best.

@2b2bff thank you, kind sir
