Here is the first answer from Hammerhead Support: Thank you for contacting Hammerhead Rider Support, we are happy to answer your questions! Here’s the quick version of what’s happening: the Karoo records the full activity data in the FIT file, including heart rate and your configured zones. When that file is imported into the Suunto app, Suunto applies its own logic to calculate and display things like zone summaries, training load, and similar metrics. On Suunto devices, those values are generated on the watch and saved using their own proprietary FIT fields. For activities coming from an external device like the Karoo, the Suunto app would need to recalculate those metrics on their end to show them the same way as native Suunto activities. Because we don’t have access to your full Suunto training history, we can’t generate Suunto‑specific numbers that will perfectly match their ecosystem. Any changes here would need to come from Suunto’s side. One thing that sometimes helps is making sure your HR and power zones match between your Karoo and Suunto profiles. We appreciate you raising this, we’ve heard similar feedback from other riders, and we continue sharing it with our Product Team. Please let us know if you have any additional thoughts around this. Thanks again for your patience and for riding with us! Best, According to @dimitrios-kanellopoulos there are no Zones in the fit-file from Hammerhead and maybe something is wrong when Hammerhead produces or exports that file. I have mentioned this in my answer to Hammerhead and sent them the same fit-File. Now waiting for their next answer.

@atoponce said in Wahoo Kickr Core 2 speed and distance: @raven On my run this morning, I realized a simple test could be starting the standard cycling sport mode and disabling GPS to see if it collected speed from the trainer. The theory being that the indoor cycling mode is specifically ignoring it. But with GPS disabled on the standard cycling mode, no speed was recorded. So at this point, it seems the best way forward would be to record the activity with the Wahoo mobile app, which does record speed, then use the Suunto API to import the activity, given that the Suunto mobile app doesn’t support importing FIT files directly. Worth a test tonight. When I got my Race S last year, I used the app HealthFit to import some older activities recorded by the Apple Watch, basically “filling things out” to make the start of year 2025. However it didn’t seem to do all the things that would be done if these had been native Suunto activities. Right now I can go to calendar view and see back to Jan 2025, but if I go to Training Zone, my CTL/ATL/TSB graphs are “wonky” until after the point I started using the watch. [image: 1773177192464-dd99bbcd-c9eb-4a7f-8269-3a6dece140a5-image.png] Perhaps I did something wrong, but this experienced convinced me of something I’ve learned with other ecosystems — companies prefer sessions to be recorded with them whenever possible. For Apple, any session recorded by a third-party makes the “Active Calories” and “Total Calories” the same value, whereas with the Apple Watch they differ, with Total including BMR while Active does not. Imports to Garmin might not update their load and recovery metrics. I don’t know the extent to how Suunto treats “non-native” sessions, but my instinct is to try to avoid that. I assume your Core 2 can send two distinct signals? If so, then my recommendation is to have one go to Suunto watch and the other to Wahoo app or whatever, then edit the “Distance” field on the Suunto session to match your app. However, my perspective may be a bit skewed as I don’t do all my analysis on Suunto. I use the site intervals.icu as I can break out my intervals for running, cycling, and most importantly rowing. For my indoor rowing I want to look at my power (watts) and cadence (rpm) data, and Suunto cannot connect to rowing machines at all so I can’t get power there, and it guesses at cadence rather than reads it from the machine. Here’s an example, a short ten minute warm up session I did today: [image: 1773177662776-a6e84e33-5bb6-468e-a725-b59131a8a247-image.png] Notice I have two pushes of one minute each where I average 171w and 177w. At the timestamp I’ve reached my HR peak of 149bpm. Meanwhile, I dual record with Suunto, and it gives me less info, only a HR graph and a fake “speed” graph that uses the reported distance (Suunto guess at it and always overestimates this but I edit it to match) and no ability to see power at all, much less get defined intervals. As I need to use intervals.icu anyway for these sort of things, my motivation with the Suunto app is to get as much relevant data to it as I can natively. So I wanted so the Wahoo import you’re proposing. Even at intervals.icu I don’t show the “speed” graph in my analysis as I don’t see how it can provide me with anything actionable. The session I showed above from Wahoo, here’s how it looks at intervals.icu: [image: 1773178070659-4a23299a-0e33-4e3c-a781-9745ec631ee9-image.png] I could turn on a speed graph, but what purpose would it serve me?

@DrSilverthorn said in Course planner feature suggestion: @sky-runner this could work. Maybe the degree to which you prefer one solution vs another is tied to how obsessively you’re watching the info I think I’d prefer the configurability of a data field option, which would probably involve fewer button presses If there was a dedicated waypoint data screen and I could customize it, I’d definitely use that. But in general I don’t like Suunto’s approach of mixing navigation specific data fields with other data fields on regular data screens. I don’t like having unused data fields when navigation isn’t used. I also don’t like an idea of having a special sport customization just for the case when I use navigation. In my opinion, navigation specific data should only be visible when I use navigation and otherwise be hidden. Garmin solved that by allowing users to customize navigation specific data screens that only show up during navigation. My eyesight isn’t that great anymore so I don’t like having a lot of data fields on each data screen (4 or 5 at max), which means with only 3 data screens I can’t even afford to waste some of the space for navigation specific data fields like distance to next waypoint or ETA. I used that in the past with Suunto 9, but would definitely prefer a cleaner solution. When I used Garmin. I always enabled the “Up Next” feature, which is a dedicated data screen that shows up to 4 upcoming waypoints with their names, symbols, and remaining distances to them.

@maszop said in New SMART barometric algorithm: @wakarimasen This has nothing to do with measuring altitude itself — that’s never been a problem with Suunto. Look at the top part of the altitude graph, and you’ll see a jagged line with multiple little, sharp peaks (caused by strong wind) that add up, giving absurd ascent and descent totals. It’s a bit better since the last update, but the results are still absurd and essentially useless for any analysis. Understood. Ascent/ descent isn’t so important for me, I guess. I’m just pleased to get to the top, and know how far there is to go on the way there. My Polar watch ‘over-read’ by 10m at the summit, for comparison.

@sky-runner said in Unboxing 90th Anniversary Edition: @Freezer When the 90th anniversary edition is supposed to ship? Some people seem to already have it. Like 2 weeks ago i was able to add Vertical 2 Limited 90th anniversary to basket and pay for it in Poland smartwatch shop. I havent seen any info its gonna be send after 10th march. Not sure if I would buy it I wouldnt already got it on my hand :D. It looks cool but as Race 2 owner I dont need it. Its cool for collectors. I’ll sell my watch when Race 3 will be released and if cool enough for switch.

I just gave up with all the sleep and recovery tracking and use it as a normal watch. More batterylife and no stress with useless functions that work when ever they feel like

@Łukasz-Szmigiel hahahahaha. I have a bug and my Codex weekly quota resets every day. For real I can prove with screenshots. I am having a party each day

@maszop totally agree! Offline re-routing on downloaded maps is perhaps the greatest Achilles’s heel of the Suunto platform and, I think, the most important difference from Garmin’s system. As said in previous posts, this Achilles’s heel is further compounded by the limited number of routes one can offload onto the SV2. I believe that watch processor and storage space are not the issues. And even if they are, why, at least, not use Suunto app on mobile device for these two jobs for eventual BT transfer to watch of gpx file (like you did with a third party app)? It’s not ideal since you have to have a mobile device on activity/exercise but you will have peace of mind that you are covered for any eventuality.

@2b2bff No question about it! I’ve also been programming since early 1990s and do that for living.

@shamilt1 Suunto uses something called FusedSpeed. It uses GPS and your steps to calculate your distance. So it is possible the calculation differs, especially as GPS coverage gets bad…

@Adrian.S agree on treadmill elavation gain, would be nice if one could edit it on the watch after the run, like distance but at least we have elevation gain in the app now for treadmill, so step by step.

I have problems with BT connection of Suunto HR belt since several months… I reported this here in different threads… others too… it would be nice if this issue would be addressed by an update!

@Tieutieu said in Climb guidance 2.0 issue - not all zoom levels are available at the end of the route (see picture): @sky-runner the only missing thing ihmo is this extra zoom level when there is waypoints . In other cases climb guidance is perfect No, it is not perfect when doing a really long distance with a lot of waypoints, and that is what the above report is about. The zooming doesn’t work correctly when at the end of the route as it may not be possible to zoom in to the desired zoom level. Imagine that you run a 100 km race and let’s say there is an aid station at 5 km before the finish and another aid station at 10 km before the finish. And let’s say there are waypoints for all aid stations. And let’s say you are just past the second from the end aid station, so basically you have 10 km to go and one more waypoint before the finish. Please see the picture at the top of the post for the illustration of what I am trying to explain. At that point it is possible to see the entire profile for the entire 100km, but the elevation profile is so compressed horizontally that it is unusable. Also it is possible to zoom just at the 2nd from the end segment of the profile - from 10km before the finish to 5km before the finish. That is good. But it is impossible to zoom into the segment that shows the last 10 km - from 10km before the finish to the finish. Instead it goes straight into the entire 100km profile. That’s what the above report is about. A similar zoom level is available at the beginning of the route but not at the end. The logic is flawed!

@markman8 AFAIK it is not related to gaskets. It’s a software/hardware issue that was well reported in this forum. It has happened to me once (Summer 2024) and the watch was replaced under warranty. There are also some forum members that had multiple failures (and replacements). It was never disclosed what the actual underlying reason was but the failure is known and quite common. Suunto might not willingly acknowledge it but from a moral standpoint they should.

@Brad_Olwin iPhone 15, latest firmware’s and App versions. I can’t help but wonder though, two things I know compared to other suunto watches: The software backend for the Run is completely different from others—evidenced by single-note tones (instead of the delightful “Suunto Song” for alarms), music, and plenty of other bits indicating its its own breed of software This is the first “spring forward” since the release of the Run—so it may be possible this bug hasn’t been noticed because it wasn’t possible before now?

Resizing the photo didn’t work. It must be specific to certain photos and certain training sessions. The photo was 7.5 MB. I took the same photo again the next day and was then able to upload it. I’m a bit baffled. It doesn’t happen all the time, but it does occur occasionally.

@Tami999 thank you for the tip !

@SergioB yes you’re right, it’s there (quite small). But I can swear I didn’t see it the first time.

@enriqueescoms did you use a power brick or did the hotel provide an USB socket, that you used?
