GarminForerunner 955 Solar review TL;DR: The new Forerunner 955 Solar offers a lot more bang for your buck than its predecessor, but it’s not without flaws. Hopefully, future firmware updates will doctor the not-so-many issues this excellent tri-watch has at the moment.
I’m a lifelong fan of Garmin’s rugged outdoor watches, including theGarmin Fenix 6 Proand theGarmin Fenix 7X, but even I must admit that when it comes to training (and especially running training), nothing beats the Forerunner line. Mid-range Forerunners, such as theGarmin Forerunner 255S, represent the perfect balance between price and features.
High-end Forerunners, like theGarmin Forerunner 945and the subject of this review, the Forerunner 955 Solar (and non-solar version), are slightly different. They are some of thebest triathlon watchesand offer more than what’s necessary for training and getting around; they showcase the newest features Garmin has to offer in a lighter package than the Fenix line.
I always thought these wearables were a bit of an overkill. The Garmin Forerunner 955 solar is not quite as overwhelming as the Fenix 7X, but it has many features you won’t use, even if you’re the most multidisciplinary athlete out there. Yet, I can’t stop wearing the watch and checking my Training Readiness score. Is the Garmin Forerunner 955 Solar thebest Garmin watchright now? Let’s find out.
(I reviewed the latest iteration of the Forerunner 900 series here:Garmin Forerunner 965 review)
Garmin Forerunner 955 Solar review: Price and availability
Available now atGarmin US,Garmin UKandGarmin AU, the Forerunner 955 Solar has a suggested retail price of $600/£550/AU$950. The Forerunner 955 (non-Solar version) is also available now and has a suggested retail price of $500/£480/AU$800.
TheForerunner 945(retailer link) is still available to buy – there is no solar version of this model – for $600/£500/AU$1,000. In the US and AU, anLTE version of the Forerunner 945is also available for $650/AU$1,050.
To be able to use the Native Running Power feature on the watch (more on this below), you’ll need eitherGarmin’s Running Dynamics PodorHRM-Pro heart rate monitor(both retailer links).

Garmin Forerunner 955 Solar review: What’s new?
The Forerunner 955 Solar might look similar to the Forerunner 945, but there are quite a lot of physical changes between the two. The most obvious is the addition of the solar-harvesting Power Glass; you can clearly see the sunlight-sensitive ring around the watch face.
Unlike its predecessor, the Garmin Forerunner 955 Solar has a touchscreen user interface with a widget view layout, similar to theGarmin Venu 2and theGarmin Epix Gen 2. And just like those two watches, the Forerunner 955 solar features Garmin’s latest Elevate heart rate sensor (v4). It also has multi-system multi-GNSS satellite support like the Forerunner 255 (and 255S).
The watch also inherited the real-time stamina feature from the Fenix 7 line, although this is now available on the Forerunner 945 LTE, too.
From a features point of view, the new additions are:

Garmin Forerunner 955 Solar review: Physical design
The new Garmin Forerunner 955 Solar has a larger, more detailed screen than the Forerunner 945, but it’s also slightly heavier.
The Forerunner 955 Solar has the standard 5-button layout with three buttons on the left edge of the watch case and two on the right. Sadly, no versions of the Garmin Forerunner 955 come with an AMOLED display, which is especially strange as the Venu 2 mentioned above has a similar display size and is fully AMOLED. Not only the screen of the Venu 2 is brighter, but it also has a much higher resolution (416 x 416 pixels).
The lens, bezel and strap material haven’t changed since the Forerunner 945: they are still Corning Gorilla Glass DX, fibre-reinforced polymer and silicone (respectively).

Garmin Forerunner 955 Solar review: Battery life
I thought it might be easier if I made a matrix of the different battery life stats of the three watches, as per below:

[Solar charging assumes all-day wear with 3 hours per day outside in 50,000 lux conditions]
As you can see, battery life has only been improved slightly, although it’s worth mentioning that the GPS chip in the new Forerunner 955 series is much better (and power-hungry) than the single-band Forerunner 945. Interestingly, GPS+Music battery life declined; not even solar can help this.
For the review, I used the Forerunner 955 Solar, but I must say, battery life felt rather underwhelming for a top-tier Forerunner. I used the watch for roughly one hour a day for GPS tracking and usually had theGarmin HRM-Proconnected to measure running power; still, I had to charge the watch more than once a week.
Based on my university-level calculations (…), even with that much GPS usage, the Forerunner 955 Solar should have lasted for around 8-9 days. I appreciate I didn’t expose the watch to nearly enough sunlight for it to make a difference, but still, I expected a bit more. I haven’t had blood oxygen on and used the watch sparingly; not sure what ‘drained’ the battery.
Maybe it’s due to the features not being optimised yet; who knows. I hope future software updates might doctor this.

Garmin Forerunner 955 Solar review: Features
The Garmin Forerunner 955 Solar comes with all the smart, health and fitness features under the sun, including all the features of the Forerunner 945.
These include 24/7 heart rate tracking, sleep tracking, stress tracking, VO2 max estimations, training status reports, smart notifications, weather reports, quadrillion sports modes, step counter, blood oxygen measurements, Body Battery… and so on.
I’ve already talked about heart rate variability (HRV) in my Garmin Forerunner 255S review (and even more in myWhoop 4.0 review) so if you’re interested in that, click on one of the links and read on. A feature that’s currently unique to the Forerunner 955 Solar (and non-Solar) is the Training Readiness.
I also talked about this new feature at length (the link can be found above), but to recap: the Forerunner 955 can estimate how ready your body is for exercise based on sleep, stress, HRV and training load. This feature finally addresses one of my biggest Garmin watch frustrations, namely that there are too many features working separately from each other.
It’s great that the Forerunner 945 offers the Body Battery and Training Load features, but it can’t tell you how these affect your body whencombined. Training Readiness brings it all together and replaces many separate metrics with one number, making it more understandable for simple people like me how hard can I exercise.

Garmin Forerunner 955 Solar review: Heart rate sensor accuracy
I found it hard to benchmark the heart rate accuracy of the Forerunner 955 Solar, mainly because it uses the same Elevate v4 sensor found in the most recent cohort of Garmin watches, the ones I use for checking heart rate sensor accuracy on other watches.
That said, I went out for quite a few runs wearing several different wearables, including thePolar Pacer Pro,COROS Pace 2etc., to see how they compare to the Forerunner 955 Solar. I also benchmarked it against optical heart rate sensors such as thePolar Verity Sense, just in case.
Not surprisingly, the Garmin forerunner 955 Solar is one of the most accurate wearables I have worn in recent times and is definitely on par with the Garmin Fenix 7X. If anything, the readings seem a bit more accurate thanks to the Forerunner 955 Solar being lighter than the Fenix 7X, making it sit better on the skin.
If you want to make sure your heart rate readings are as accurate as possible, I still recommend investing in a heart rate monitor, especially in the HRM-Pro: it not only provides you with bang-on heart rate stats but also running power and other advanced running metrics.

Garmin Forerunner 955 Solar review: GPS accuracy
The Garmin Forerunner 955 Solar picks up GPS signal incredibly fast. And I meanfast. I step outside the house, turn the run mode on, and two seconds later, the GPS is locked on. I remember, even a few years ago, you had to wait a good 15-30 seconds for the GPS chip to latch onto the signal; those days are gone.
GPS accuracy is okay. It’s better than okay but not perfect. I tested the watch in parks and the city; in the former environment, the watch struggled a bit with real-time pace readings.
For example, I did plenty of Daily Workout Suggestion sessions where you have to run at a certain pace for a specific timeframe. On one occasion, the watch asked me to run for one minute at a 3:40 min/km pace. Throughout that one minute, it kept saying my pace wasn’t fast enough (real-time pace), but when it gave me the overall pace for the segment, it was actuallyunderthe target.
This happened under some tree foliage; this might be the reason for the poor pace readings. However, you’d think the multi-system GNSS support is there for precisely this reason; to strengthen the signal when the satellite visibility isn’t excellent. I’m not an engineer, so I could be wrong (I probably am), but I expected even better results from the Forerunner 955 Solar.
The route is accurate on the map, at least, with only a few instances of inaccuracies. And again, GPS is super fast, so there is that.

Garmin Forerunner 955 Solar review: Verdict
The Garmin Forerunner 955 Solar is a huge update from its predecessor. It offers a lot of extra features and newer sensors for almost the same amount of money you had to pay for the Forerunner 945.
From a physical point of view, the Forerunner 955 Solar looks very familiar but adds a bigger screen with better resolution and, of course, the solar-harvesting Power Glass, which can help extend battery life, should you spend enough time training outside.
Some of the new notable (possibly battery-draining) features include the currently Forerunner 955-exclusive Training Readiness (gives you a score on how ready your body is for training on a scale of 0-100), Morning Report (a recap of sleep/HRV stats, plus workout suggestions) and the handy Race Day Widget (which also tailors Daily Workout Suggestions).
Not all new features are mind-blowing or even brand new, but all add to the overall feature-richness of the Forerunner 955 Solar. Add in the new sensors and GPS chip, and you have yourself a fantastic triathlon watch that’s a must-buy for any self-discerning triathlete.
Garmin Forerunner 955 Solar review: Also consider
For any non-diehard runners, cyclists and triathletes, theGarmin Forerunner 255S(or the standard-sized Forerunner 255) is a better option. It’s cheaper and has both the new optical heart rate sensor and the new multi-band GNSS support as well as the HRV feature. It’s the perfect balance between price and feature, as long as you can live without the AMOLED display.
TheGarmin Fenix 6 Prois an older watch (older OHR and GPS) but it’s still a superb multisport watch option. The Pro has a more premium build (especially the Titanium option) and continuously received updates – an excellent choice if you need a capable Garmin that looks good on the wrist.
