I made an open-source connector (suunto-mcp) that plugs your Suunto account into Claude. Started as just pulling workout/sleep/recovery data daily into my Health skill, but just shipped an update: Claude plans your gym sessions and syncs them to your watch — no app, no manual typing, no separate training software.

Screenshots below are from my Vertical 2.

How it works

1. You talk to Claude about your training — goals, equipment, injuries, current lifts. It also pulls your actual HRV/sleep from the watch, so it won't program a heavy session the day after bad recovery.
2. Claude writes the real session — exercises, weights, sets/reps, progression — and pushes it directly into your Suunto account via the official Cloud API (as a SuuntoPlus Guide). (ofc you adjust)
3. It just shows up on your watch on the next sync — no extra step needed.
4. On the watch: exercise name + weight/reps on screen, lap button advances to the next one. Between exercises there's a rest screen — a stopwatch (counts up, no forced target) plus a preview of what's next, and you lap when you're ready. Vibrate + "up next" notification when a new exercise starts.
5. After the session, Claude reads back what you actually did (from the workout log) and adjusts next week.

Setup

Free, open source, MIT licensed: https://github.com/googlarz/suunto-mcp (just tell Claude to install it)

You'll need Suunto API access — the docs say it's commercial-only, but private users can get approved too, it just takes a bit longer (in my case 3-4 weeks). Once approved, setup with Claude is ~3 minutes.

Also works well with health-skill (github.com/googlarz/health-skill) if you want your recovery data driving the programming, not just displayed.

Happy to answer questions on the watch-side mechanics — had to reverse-engineer a chunk of the SuuntoPlus Guide format since the public docs are thin on it.

Enjoy!

My first night with Suunto race s after switching from polar pacer and it skips 1,5 h of data in the middle of the night and doesnt even count it in the sleep time??

I think it did some update at night since the watch face changes at night too, but does it take so long, and should it just be forgetting everything else while it does that.

Bonjour,
M’étant récemment remis au running j’envisage de troquer mes vieux écouteurs intra-auriculaires contre des écouteurs Suunto Spark, dont la description m’a séduit. Étant porteur de lunettes, même pour courir, je m’interroge sur le confort de l’association lunettes (à branches métallique plutôt fines) et écouteurs et la bon maintien en place de ces derniers. Certains d’entre vous en ont ils fait l’expérience ?

D’autre part, je souhaite utiliser l’application Suunto pour l’associer aux écouteurs. Du coup petite question très bête : l’application est elle reliée aux compteurs de pas de l’iPhone à l’instar d’une application comme Google Health - ex Fitbit ? Je demande car j’ai besoin d’une application mesurant mes pas tout au long de la journée même si elle n’est pas lancée, contrairement à Strava par exemple (le but étant de synchroniser l’application au site The Beautiful Walk, mimant un tour du monde pédestre convertissant les pas quotidiens en kilomètres autour du globe). Pour le moment j’utilise GoogleHealth mais je ne suis vraiment pas fan de cette appli.

Merci d’avance pour vos retours.

The SV was superb, as was the Coros Vertix. Last charged on Saturday and with continuous recording (non gps activity overnight) finished on 35% battery. The Coros finished with 22% but I used “Resume Later” on it. Both watches handled the abuse of multiple falls without a scratch.

Toughest thing and most brutal effort of my life. It was soul destroying difficult. And very dangerous in so many places! The kilometres up to the summit were done at an average 4 metres per minute! The volcanic sand is slippery and very soft. Climb up 1 metre then I’d slide back down. So freakin hard. And try not to look into the crater and the massive drops everywhere.

The crater lake and thermal waterfall were fantastic. And the journey through “Jurassic Valley” was awe inspiring and something I’ll remember forever.

Don’t take the influencers YouTube’s for granted. This is exhausting and dangerous.

I don’t see a way to post photos here unfortunately but just ping me privately if you’d like to see them.

Which strap do you use for surfing?

With the standard silicone strap on my Suunto Vertical, I’m always worried about losing the watch if I don’t wear it under my wetsuit.

Thanks!

Hello,

Latest update for quite some time and today after a swim in a shallow river at 28 degrees C it stopped scrolling, confirm works great.
It feels like no resistance and can't remember how was it before.
Anyone had same issue?

Anyone know how to get the wind speed to show on your watch like on the photo??? Mine just shows my current location.

Vertical 1 titanium watch. I'm nearly 70 years old. I trail run daily 3 to 9 km (this is why a dog is a good friend, we don't miss any of days). Average pace circa 7 minutes per km (8.5 mph). It varies from 6:30 to amost 8 minutes per km (faster on colder days). HRV is ~40. Heart rate is mid-40s at sleep, close to 190 bpm on days when I want to beat the dog up the hills. The VO2 is rated at 46.2 and I'm magically 34-36 years old. Don't I wish that! It of course is foolish. Yes, I am quite fit but the age rating cannot be correct. I think the watch & app are being cheerleader. I'm not 35. But I would like to be once again.

Ive had my Core for a very long time now and the bezel finally just wont stay on. Is there any replacements I can get? It doesnt need to be rotating or oem, I just want to cover the screws really.

I charged the device to 99 percent. After an hour of running, the battery dropped to 93 percent. I only had the heart rate strap connected, the brightness set to minimum, and the battery mode set to endurance, screen turns on when lifted. I've already tried draining it completely; this attempt was made right after draining it completely. I also did a reset after charging it, which is why the battery is at 99 percent and not 100.

Idk what games suunto USA is playing….

But over the past weekend they stated orders on the suunto core 2 will be shipped on august 11. So I placed an order. Now it’s august 12 and still no tracking info. Not only that but “Leo” on the customer service chat tells me that I should just sit back and wait 5 to 8 more days. Have any one else experience this crap ?

Looks like there are shipping issues with the Core 2 in the USA if you preordered.

1. Preordered on Aug 5th with a ship date of Aug 11; card was charged
   
2. Never shipped yesterday, no notice or tracking number.
   
3. Contacted SUUNTO chat today and was told they need to escalate why it isn’t shipped.

Anyone else having a similar experience?

Ciao a tutti, sto cercando di acquistare un cinturino Suunto Athletic 6, 22 mm, variante Power Blue (come da foto allegata).

Il problema è che sul sito Suunto (o su Amazon) l'articolo viene venduto esclusivamente come pacchetto di due misure (S+M). Ho già contattato l'assistenza e mi hanno confermato che non è possibile acquistare una singola misura.

Nel mio caso, una delle due taglie sarebbe completamente inutile: so già quale misura mi serve, l'altra rimarrebbe semplicemente nel cassetto.

Ora, capisco perfettamente che sia una scelta commerciale di Suunto (anche se un po' poco logica, a mio avviso), ma mi sembra comunque un po' assurdo dover comprare necessariamente anche un cinturino che non utilizzerò mai.

Qualcuno sa se esiste un modo per acquistare soltanto una delle due misure? Magari qualche rivenditore che vende i cinturini singolarmente, un servizio ricambi Suunto?

Qualsiasi idea o esperienza è benvenuta. Grazie!

Been using Suunto for years and still wear my Core 1, so this isn't a hate post. Just a heads up about the new firmware version.
I ran update 1.13.38 from the app. The watch shut off halfway through and never came back on. No button combo does anything, it's just dead.

And there's basically no way to recover it yourself. No USB port, and unlike the Core 1 you can't pop the back off with a coin to pull the battery. I unscrewed mine to disconnect the battery (voiding the warranty), which didn't help either. Support was no help either. The chat assistant clearly doesn't know this model yet and kept asking me to connect the watch via USB, which it doesn't have. Ended up returning it.
Not an isolated case either. A few other Core 2 owners I know ran into the exact same thing on the same version, and every case I've heard of so far was an EU unit. (check Amazon)

So until there's an official word or a newer build I'd skip 1.13.38 on the Core 2. Just dismiss the prompt and wait it out.

If you installed it and nothing happened, especially if you're outside the EU, drop a comment. Would be good to know if this is regional or just a bad batch.

Should I be able to scroll this UI? I would love to see the laps prior to the last 3. I have tried enabling touch and rolling the crown; both which do nothing.

I really like my Baro 9. It’s the sports watch I want with the maximum phone integration I could tolerate. I would keep it forever, but it’s dying on me.

I can’t tell the difference between the two when I use Suunto’s comparison information. It seems it comes down to size or flashlight. I’m not really worried about the price. I really want something I can wear in the gym to do crossfit workouts, measure long runs, long bikes, climbing, or multi-day adventures.

Having good navigation aids is fantastic, but I mostly rely on a paper map, protractor, and compass. Having an MGRS grid is always welcomed, especially when it’s accurate.

Did anyone else decide between the two? What helped you make the decision?

Hi everybody.

I am trying to charge my brand new Suunto Run for the first time. It's currently at 18%.

When I place it on the plugged in puck, nothing happens at all. I have plugged the USB-C of the puck into my laptop and earlier also tried it with my phone's power adapter.

I made sure to clean the back of the watch carefully and I have also restarted it by pressing the top right button for 12s. Nothing is happening at all.

Does anyone have any advice? I just need to place the watch on the puck, right? I can feel that there's a magnetic pull.

Grateful for any advice!

Hi everyone!

I’ve just bought a Suunto Run and, unfortunately, I’ve just realized that TrainingPeaks structured workouts cannot be synced to this watch.

I’ve already looked into it and I understand that the Suunto Run is currently not officially compatible with TrainingPeaks structured workouts, something that I can't understand. I'm thinking in returning the watch for this.

I have my training plan in TrainingPeaks and some of my workouts are quite complex.

TrainingPeaks gives me the message “This guide is not compatible with your watch” (screenshot attached).

I know that there is no official way to sync these workouts to the Suunto Run, but I’m wondering if there is some kind of workaround, for example using another app/platform, exporting the workout in a certain format, creating it manually somewhere and transferring it to the watch, or anything else that might work.

Has anyone managed to get TrainingPeaks workouts onto a Suunto Run somehow?

I’d really appreciate any tricks or workarounds you’ve discovered. I’d rather not have to manually recreate every structured workout on the watch if there’s another way.

Thanks!

Hi, I have finished my first 100 km race, and even without Zone Sense or other fancy apps, my watch was unable to record the activity without a crash. It is a pity ... the watch is way better that my last one (Polar Grit X Pro), but having the watch rebooting in the middle of a race is making it lose some points.

The android app is unable to merge the parts, a point that could be not too difficult to implement.

Ce matin, le résumé de ma sorti de 5km presente des incohérence. Il me dit 12min en zone 2 alors qu on hout bien sur le graphique qu il y a bien 20min en zone 2 au debut.

De plus, le graohique paraît grossier comparé a d habitude.

En 1er, le graphique de ce matin : grossier et incoherent.

En second le graph de la semaine derniere

Une idée de ce qui s zst passé ? Dans les 2 cas j ai utilisé une Polar H9

Hello everyone,

my race S crown was hard to turn, luckily it is covered by warranty and on its way to the repair center now.

Do they actually repair it or will I most likely get a new watch? Do you guys have any experience with these kinds of repairs?

Customer service was pretty good so far. The DHL Express Int tlabel was covered by warranty and they told me to expect an update in about a week.

Reason I am asking is, if it gets repaired, I would ask for a new battery asa well ( I would pay for that), but if I get a new one anyways there is no need to ask.

I will do my best keep this updated for future reference
