@RobinJ said in Suunto Race open water swimming GPS problem: Hi @Mechanicus, i experience the same openwater problems. I bought the Race late oktober 2024 and i was very happy with the Race as it was almost spot-on with the other watches in my group (mostly Garmin). A lot better than de S7 which i had before which always added an extra 10% on every swim. During wintertime we stayed in the pool (which is okay with the Race as long as you don’t stop during a lane) But…when we started outdoor swimming in the beginning of april 2025 all my results are terrible. On a 2K5 swim the watch added at least 500 meters. Last week my Race is exchanged for a new one because the screen was burnt-in after only 6 months in use (very disapointing, even de S7 was beter in that way) This morning (with the new watch) a 3K1 swim (all Garmins say) but Race made a “fantastic” 4K8 (!) out of it. ps this was in “endurance” mode, but all other swims in 2025 were in best possible mode You would allmost think has anyting to do with the latest fw update Hi, Can you share GPS tracks from your last swim? There shouldn’t be such differences! I have Suunto Vertival and recently I swam with friends: First swim OWS 1.3 km - SV1 watch + SV2 watch, difference in measurement about 30 meters. Second swim OWS 3.1 km - SV1 watch + SV2 watch + Garmin 955 F watch, difference in measurement about 40 meters. Software: 2.40.44 [image: 1749550012378-ows-suunto-vertical-1-3-km.jpg] [image: 1749550029384-ows-suunto-vertical-3-km.jpg]

After a night sleep I don’t get any resources filled out. I haved according to the watch 8.5 hours of sleep and I lost 1 % of resources during slepp, from what had remain from previous day. OK HRV was very low and I wake a few times, but still, lossing resources during sleep after staying in bead 8 hours?! OK, let’s say, maybe a medical condition, or yes stress, but even so daily I have inconsistent data and updates even in watch or app on Android regarding data of sleep, resources, efort estimation trend. I have the watch for almost 6 months, and it seems that Suunto it make codind test testing on the behalf and patience of the clients. Why to invest in to a team of code tesingt when the clients it doing so. Ok, I can understand that the data from field is more statistical good and reliable but the data server is on your side Suunto, and the software also on your side

@Kraisun-Tunta Yes, I would also love to get it. I think a lot of runners have injuries sooner or later. GTC helps a lot to monitor the recovery

Same problem here: Swimrun S last week-end Suunto Race S Running sportmode with Swimrun app résult: the app didn’t detect any of the 5 swim section …

I was looking for another solution and noticed that my Suunto app wasn’t up to date (I had 5.2.5 instead of 5.3.5). I updated it, and just a few minutes later, notifications started coming through again! Happy

@wakarimasen Yeah it is real. I have come off being healthy for a minute though and it is interesting how terrible Garmin is at tracking health metrics. I think that they work if you are living the healthy life and stay within the lines for the most part. Plus you have the endless drumbeat of the cult telling you everything else is garbage because it doesn’t have a flashlight or music. Two problems easily solved without paying over $1000 for a watch. I am much more in tune with my body and where I am at with training with Suunto. I think you will be too. This wakarimasu.

For what it’s worth, this is a follow-up to my comments 9 May 2025. After observing the same random spikes in HR measurements on a Garmin watch I thought I trusted as I saw on the Suunto Race, I anecdotally tested the Race again (very mildly). Basically it seems like the Garmin watch I used and the Race for me provide fairly similar HR measurements. If anything, the difference appears to be smoothing. I suppose Garmin might use a different algorithm to flatten the OHR measurement provided by the operating system, at least compared to the Suunto OHR measurement output. This is a total guess based on simple observation with no motion, periodically over a few days. I updated to the recent 2025Q1 firmware. Maybe that is a factor? Honestly I don’t recall why I thought the watch’s OHR measurement was “wrong generally 85% of the time” because it seems solid now – at least enough for me to be comfortable using it for guidance. Which is great, I really like the watch. Note I observed the same issue with a Coros Vertix 2S. In Coros documentation I found a reference to OHR measurement accuracy in relation to cold hands, as the blood flow changes under certain conditions and this can have an impact on OHR referencing. For the record, I live in Alaska and this is totally a plausible situation for me. It was the first I read about the idea, which makes sense. Just a thought.

So now we have to set up a set like this: RUN + Wing = Light weight Race + Aqua = Heavy weight

@maszop Well, I create my waypoints in the Suunto App only, and I also have this problem that sometimes the name shows properly and sometimes it just shows ‘Waypoint’. In fact, because of issues like this one I almost gave up on the bother of creating them - half of the time it doesn’t show the name and, more importantly, even if it shows the name, you can only see it in those two pop-up notifications (after the previous waypoint and shortly before the actual one)…

Just to notice : since I went to an iPhone 16 that makes larger pictures, I wonder if there is some kind of « maximum size and/or resolution » of picture we can upload to SA. I very often can’t upload pictures unless I resize them

I am comming back with some updates regarding sleep and VO2. During the sleep the VO2 value seems to be in to an acceptable range:94-100. Let’s say up to some point, accepting tolerance plus my body health. If I want, at request, to measure my blood Oxygen still is a totally mess. The measurement takes tens of seconds, most of the time, the value is far away from reality, like in between 72-85. Only after 2-3 measuremnts i get something close to reality, if I manage to make make 2-3 measurement. Why? Basically is trying to measure like 30 seconds and then the watch is saying unable to measure. I position the watch as mention in Suunto manual, also on top of my arm, also I have try under the arm, having an hairy arm. Some behavior. Also arm in different position and trying not to move. Even that is workin randomly, most of the time I cannot have 2 consecutive good measurement. How that during the sleep is working and at request not? The syncronization regarding watch and phone is working right now, at least up to now. Also the nap is summing during the day and I have a total slepp time for the entire day.

@aiv4r It should be an option and be disabled by default, so no one would be bothered and anyone would be happy.

@Anthony-Guillemette I also noticed that when editing routes during an active activity, the watch starts to go crazy when syncing during the activity. Once it restarted, another time all routes disappeared from the watch even though SuuntoApp claimed they were still there. Suunto Vertical.

@maszop For me it happened after half an hour of hike, in Serbia. Never had that problem before and I usually hike in that region often, and I was on the same track few times before without any issue. I’ve had hikes of 10 hours long and never had a crash so I don’t think that region or duration of recording is thr problem. I wouldn’t even mention this one craeh here if I didn’t saw that other people had same problem recently. P. S. I had 4 more activities recorded after the crash without any problems

@isazi this is interesting because on all previous watches I owned (S9B, 9PP, Vertical) I’ve got an instant reading after the very first run, independent of whether it was a trail run or normal run. This just started with Race, so I am not sure if there was a change of the algorithm or what is different. But I am glad it’s finally working : )

@isazi so I have my watch back from service (HSH service from Prague), they wrote me that they changed pressure sensor and gaskets and they did some tests, but when I received my Vertical and calibrate altitude my barometer has same error as before the repair. that is quite strange…
