@cosme.costa Yes, I am also struggling with the settings. It is available on the RaceS, but not on the Vertical 1. I am suprised and confused… So not really a solution so far. Its possible to “enable” backlight on the V1, whatever that means. Always on, adaptive to the sun? But then the battery lifetime is cut in a half(!) Edit: I think I found it. In the general display settings there is a “Standby” option. This enables adaptive backlight for activities - and unfortunately also for Watchface usage. @cosme.costa I now understand what you mean…

I created a support case in Komoot with the GPX and a photo that shows the offset. I should not (this is not my job) but it’s also I can do with my track. I’ll keep this thread updated with their info (if there’s any). I also sent comments in the Suunto App. I made some manual fixes but I’m not sure that an edit of the passing points will make any effect. I also fixed the end at tat mountain in Komoot but this is not good at all . I should not edit anything downloaded (in this case I know the track, but that will not happen in a track of a place I have never been). So I’ll test this edited track. I understand I have (at least) fixed the end at the top of the mountain (and the out of the route and the bad climb guidance notifications will not be triggered in that point), but the rest is really a mistery. Perhaps Route Planner is the solution. If you can make the imported GPX tracks have turn-by-turn, that’d be really fantastic.

This problem exists since November 2025… it’s a little bit annoying

@Nandodiver can you share the link please?

It also happens with the Suunto Run. And it’s not exclusive to the Chest Strap. Using Bluetooth phones to listen to music also makes this issue appear. The issue almost always appears after around 1h training, pauses or GPS disconnections during tunnel passages.

@Francesco-Pagano Maybe a bit sticky, but so comfortabe Looks great, I agree, fits better than original one.

@halajos Looks very much like clone, or exactly the same product under different branding, of Morpheus M7 HR belt. Morpheus works great for ZoneSense, plus I haven’t experienced any drops or disconnections like many people report here with their Suunto belt or Polar H10. Around $40, looks like a solid choice compared to M7 at ~$100.

@Egika and it works great! Suunto Chest HR strap can only connect to 1 device at a time. Before the update I had to pick my Race 2 or my Hammerhead bike computer. Now I let the HR strap connect to my watch and broadcast HR to my Hammerhead. Problem solved.

@SRS2000 you can only have one max HR. It is impossible to have more than one. Even more it doesn’t matter as it is the top of your zone 5 anyways… Suunto Run is a bit different than the rest. With the others you have to set the zones yourself - more control, but a bit more hassle at first.

Yesterday I restarted the watch before run activity and there was no reboot.

Hello, On the 24th, I conducted some tests, first on a practically straight route, and then on a route in the same area with hills and curves. My hypothesis that the Race 2 is incorrectly processing the recorded points was confirmed. The straight route is marked every 500 meters; it was 4.04 km according to the Race 2 and 4.05 km according to the track, measuring almost exactly during the activity. During the activity with curves, the problem returned, subtracting 80 meters from the total: 4.00 km according to the Race 2 and 4.08 km according to the track. I’ve attached some screenshots that I will send to Suunto support: [image: 1777273901039-captura-de-pantalla-2026-04-27-085958.jpg] [image: 1777274020950-captura-de-pantalla-2026-04-27-090132.jpg] I encourage you to conduct these tests and also send them to Suunto (support@suunto.com). It’s the only way they’ll take the issue seriously. If this problem is widely known, I doubt Suunto will sell another Race 2 at its current price. Regards.

@sartoric ok thanks for the info. I guess it will never be fixed then.
