When you’re in any respect acquainted with Garmin’s wearables, you realize that GPS-equipped operating watches have all the time been the corporate’s major energy. Garmin’s health watches have been a staple amongst athletes attributable to their options that are not discovered on Fitbits and Apple Watches. The Forerunner collection remains to be the place the corporate introduces a few of its most modern monitoring and coaching options.

The Forerunner 955 continues that custom. It sits atop the Forerunner collection as probably the most feature-packed watch within the bunch, and this 12 months it positive factors some trendy touches like a touchscreen and day by day train readiness assessments (à la Fitbit’s Each day Readiness characteristic, however free to customers), whereas introducing new options not current on every other Garmin watch. That features the higher-end Fenix collection of watches, from which the Forerunner 955 can also be beginning to steal some cues, like solar-charging choices and multi-band GPS.

We educated with the Forerunner 955 for a number of weeks to see how its latest options enhance on a platform we already love and to find out simply how afraid Garmin must be about Apple or Fitbit catching up.

A brand new touchscreen, photo voltaic choice, and multi-band GPS

The Forerunner 955 has an analogous design to the 945 earlier than it, however that is the primary Forerunner to include a touchscreen show you possibly can disable manually or robotically throughout actions. It is also the primary Forerunner to characteristic a photo voltaic charging choice for a $100 premium, and it is the primary with multi-band GPS help. Multi-band GPS supplies extra correct location monitoring that’s extra dependable in difficult environments. The characteristic was beforehand reserved for Garmin’s highest-end trackers.

The 955’s face grew a tenth of an inch, widening the show to 1.3 mm and permitting for a brand new digitized second hand going across the edges of the display screen. The solar-charging model provides a neat reflective rim across the watch face the place it soaks in daylight for a bump in battery life. Altogether, this makes for a barely greater watch than its predecessor, however it would not bulge off your arm like Garmin’s Fenix or Epix watches may.

Underneath the hood, we nonetheless have sensors for coronary heart fee, blood oxygen monitoring, GPS, and 32GB of storage for music. The Forerunner is rated for 5ATM water resistance, and it will probably function from -4º F to 140º F.

Identical OS, new touch-based interactions

Garmin hasn’t tweaked the aesthetics or mechanics of the OS a lot, as a substitute specializing in refining and creating new monitoring options. I don’t have any qualms with the UI—they get the job finished—however it was good to see the introduction of interactive watch faces on the platform. It’s not a lot, however the default face has a carousel of quick-view stats you possibly can faucet via that embrace VO₂ max, coronary heart fee variability (HRV), coaching load, and exercise minutes.

Garmin’s inexperience with touchscreen interfaces is clear on the Forerunner 955. It’s not instantly intuitive what every icon is telling you, and it will be useful when you might long-press every of them to see extra info, very like how watch face problems on the Apple Watch work. Hopefully, this type of touch-optimized interface enlargement will come quickly.

New Coaching Readiness scores and assessments

Garmin’s sturdy go well with continues to be its free, in-depth well being metrics and coaching evaluation. The corporate is leagues forward of its rivals in offering coaching enchancment options and sport-specific assessments (significantly operating, but in addition biking and swimming to barely lesser extents).

With the 955, Garmin additional refined these metrics for accuracy whereas including two extra mainstream options: Coaching Readiness and Morning Report. Coaching Readiness makes use of your sleep rating historical past, coronary heart fee variability, stress historical past (based mostly on HRV), restoration time since your final exercise, and Garmin’s Acute Coaching Load characteristic to evaluate how prepared you might be to train day-after-day.

Assessing your physique’s restoration and readiness to tackle stress (bodily or mentally) is one thing that has gained steam within the wearables market over the previous few years.

Garmin would not reinvent the wheel right here; not one of the metrics that go into creating this rating are new to Garmin’s suite. Your Coaching Readiness rating, very like assessments from different trackers, is only a fast technique to see how prepared you might be to work out. Garmin exhibits every issue’s ranking (sleep rating, HRV standing, and many others.) in a listing on the watch and within the companion smartphone app. That is the primary time you’ll be capable to see discrete HRV knowledge. Beforehand, that knowledge was measured by Forerunner units for the calculation of assorted proprietary metrics like its Physique Battery, stress, and sleep assessments.

Perplexingly, Coaching Readiness offers you entry to extra knowledge and context via the watch’s eponymous interface than the smartphone app, and I’d a lot want that Garmin make it potential to faucet into extra context for every issue instantly from the Coaching Readiness menu in-app, because it does on the watch.

Morning Report

Morning Report is a simple characteristic designed to present you an summary of your day. It pops up on the watch display screen each morning after you get up and stays there for about an hour earlier than dismissing itself when you don’t work together with it sooner. When you do click on into it (through the watch’s button), you’ll get a quick rundown of your day, which might embrace your Coaching Readiness rating, sleep evaluation, a exercise suggestion for the day, HRV standing, climate, calendar occasions, physique battery, depth minutes, and steps.

The exercise options are running-based and range in distance and time objectives. Annoyingly, the Morning Report notification is the one place you possibly can see that day’s exercise suggestion. Different bits of the Morning Report (climate, Coaching Readiness, and many others.) can be found elsewhere within the app and watch, however there’s no technique to recall exercise options on both.

Tried and true, deep, and particular coaching metrics

My favourite characteristic of Garmin watches continues to be their suite of coaching analytics. I’ve highlighted them in quite a few shopping for guides and opinions because the characteristic that units Garmin units aside from every other health trackers, together with the newest Apple Watches. This revamp solely builds on that lead, even because the Apple Watch is ready to achieve superior operating dynamics for the primary time, one thing Garmins have lengthy had.

Coaching Standing, Coaching Impact, Coaching Load Focus, and Acute Coaching Load are a number of of the deeper metrics Garmin presents to indicate your total coaching impacts and the impact of a particular exercise in your coaching progress. In addition they present your stability of excessive cardio, low cardio, and anaerobic train for the previous week and previous 4 weeks. They’re all impressively digestible and helpful assessments.

If I’ve been coaching exterior of my optimum weekly coaching load, I understand how to reinforce my routine to keep away from damage and let my physique get well. If I’m attempting to enhance my cardiovascular endurance or my physique’s skill to expend most vitality for brief intervals of time, Coaching Impact lets me understand how every exercise impacted both of those objectives, whereas Coaching Standing lets me see how constant I’ve been and whether or not I’m nonetheless progressing or coaching at too excessive or low of an depth. This type of quick, results-oriented suggestions isn’t simply encouraging, it’s addictive.

The Forerunner 955 introduces refinements and additions to Coaching Standing and Acute Load that enhance accuracy by being extra contextually conscious. As an example, when you’re utilizing Garmin’s Race Calendar characteristic, your preferrred Acute Load will contemplate the aim of getting ready on your particular race. Garmin additionally robotically creates a coaching plan to satisfy your aim time/distance for the race and suggests exercises every day that can assist you advance towards that aim. Acute Load scores have additionally been tweaked in order that more moderen exercises influence your coaching load greater than much less latest ones. In different phrases, a heavy coaching day six days in the past will influence your present Acute Load rating lower than the identical exercise finished yesterday. This offers customers a greater sense of the pressure their our bodies are below on a day-to-day and weekly foundation.

You can tap your Training Status to see all the factors going into the assessment.

All these instruments are helpful, straightforward to grasp, well-contextualized, and free, not like the instruments from a few of Garmin’s rivals. I’ve all the time valued Coaching Impact’s insights and accuracy probably the most. It has persistently felt like a trustworthy illustration of the work I put in, and it obtained me hooked on hitting completely different objectives to influence my most well-liked space or focus or stability my coaching.

The Forerunner 955 did effectively with its measurements all through a number of boxing and energy coaching classes. The information was all the time inside what I perceived to be an correct vary, given my efforts. Garmin makes use of your exercise stage, sort of exercise, age, top, weight, gender, and coronary heart fee to estimate calorie burn throughout actions. It’s just a little harder on calorie counts than an Apple Watch, however not by a lot, sometimes inside 30 to 50 energy. The Apple Watch and Forerunner watches often award extra conservative calorie burn estimates than Fitbits.

The 955’s sleep evaluation confirmed enchancment over earlier Garmin watches in estimating fall-asleep and wake-up occasions (trending very near outcomes from probably the most correct sleep tracker I’ve examined, the Google Nest Hub), however it nonetheless overestimated my awakenings (frequency and period) all through the evening as each wrist-worn tracker I’ve examined has.

Actual-time stamina assessments for runners and cyclists

I’m coping with a knee damage, so I used to be unable to go for runs or bike rides with the brand new Forerunner. Meaning I couldn’t check the brand new real-time stamina characteristic, however most of what goes into this evaluation is a combination of metrics Forerunners have lengthy had, like lactate threshold and VO₂ max, distilled into real-time operating knowledge slightly than an after-the-fact bit of information as beforehand offered. Having spent lots of time operating and biking with Forerunners, these are metrics I’ve used and relied upon extensively up to now to evaluate progress and plan routes. The one distinction is which you could now see your pacing and cardiovascular limits in actual time slightly than in a graph after your train.

Actual-time stamina is a brand new addition to the Forerunner collection, particularly and completely on the 955 in the intervening time. It makes use of your VO₂ max and most coronary heart fee to estimate what share of effort you’ve used (and conversely, how a lot you continue to have within the tank) whereas additionally projecting your tempo at any given second throughout a run or cycle. Different components that may contribute to your real-time stamina are your lactate threshold/purposeful threshold energy (FTP) and present depth assessments.

Lactate threshold and FTP are primarily the identical sort of metric; they each measure exertion. Lactate threshold is extra generally used for runners, whereas FTP is geared towards cyclists. Each estimate your muscle’s time to fatigue below numerous intensities of train. These intensities are damaged down into zones. For runners, there are sometimes 5 zones that delineate completely different percentages of your max coronary heart fee. Cyclists utilizing FTP often have seven zones based mostly on energy output in watts. Watts don’t imply a lot to most individuals, so units like Peloton bikes, Garmin watches, and others merely talk every zone as a measure of your coronary heart’s capability, because it’s instantly tied to how a lot energy you possibly can put out.

Each Lactate Threshold and FTP are measurements that require extra equipment with the 955 (or any Garmin watch) to attain the very best accuracy, or within the case of Lactate Threshold, work in any respect. For lactate threshold measurements, you’ll must pair Garmin’s HRM-Professional chest-worn coronary heart fee strap with the Forerunner to take assessments. That may even work to some extent for FTP evaluation, too. However to get probably the most correct FTP evaluation, you’ll want a foot pod accent as effectively.

Fortunately, you don’t want an HRM-Professional to get real-time stamina assessments, however it’s nonetheless price contemplating for runners and cyclists to allow higher monitoring. The HRM-Professional will get a extra dependable coronary heart fee measurement utilizing electrodermal sensors than the optical sensors on wrist-worn watches.

The opposite large causes to contemplate pairing your 955 with an HRM-Professional are superior operating and biking dynamics. These are assessments and knowledge that Garmin has lengthy had on supply with the pairing of an HRM-Professional and suitable watch.

The HRM Pro isn't mandatory for most advanced metrics, except for running dynamics like vertical oscillation, stride length, etc. It also makes a number of more complex measurements more accurate.

Corey Gaskin

With an HRM-Professional, the Forerunner 955 supplies superior operating dynamics that embrace vertical oscillation, vertical ratio, stride size, cadence, operating energy, floor contact time, and left-right contact time stability. Out of this lot, stability evaluation and vertical ratio (which exhibits how environment friendly your strides are) are the 2 lacking options from Apple’s operating metrics for Apple Watch. As are deeper metrics like lactate threshold/FTP, which merely don’t exist on Apple Watches (or every other wearables).

Past that, cyclists get a small suite of cycling-specific superior metrics that don’t require an adjunct. That features “grit” (problem) and “circulate” (sustaining velocity) scores for mountain biking and a normal evaluation of your Practical Threshold Energy. A extra correct studying requires an HRM-Professional and energy meter pedal equipment like Garmin’s Rally or Vector bike pedals.

These generally is a bit dear, however they provide deeper biking dynamics and mountain biking dynamics that add bounce metrics to the info suite. With the pedals, biking knowledge grows to incorporate left/proper stability, pedaling energy stroke evaluation, and time spent seated or standing to gauge effectiveness, amongst different knowledge.

If all that has your head spinning, simply do not forget that the 955 additionally has a few of the most foundational and helpful instruments for runners/cyclists, together with preloaded topographical maps with using/operating programs and turn-by-turn navigation. They don’t require mobile connectivity, and you’ll even set the course to keep away from unpaved roads. The 955 can also be the primary Forerunner to throw in cross-country snowboarding trails and ski resort maps as effectively. Additionally new is a map supervisor so as to add and take away maps proper out of your wrist.

Selecting the place you wish to go is straightforward with turn-by-turn steerage. You may select something from eating places and factors of curiosity in your space to transportation and close by parks—all from the operating exercise display screen in your wrist.


There are six preloaded biking regimens to select from. A few of the operating and biking applications provide you with a alternative between two trainers and their coaching strategies earlier than opting right into a program. These applications are aided by introductory movies from every coach. However all applications begin with a questionnaire to tailor the construction to your wants and help you see the complete program routine.

The Forerunner 955 is getting ever nearer to the next-level journey prowess of Garmin’s Fenix watch line with a handful of added software program options and {hardware} integrations like multi-band GPS and photo voltaic charging. Among the many software program additions are the Up Forward characteristic, which exhibits upcoming landmarks alongside your route, and Garmin SkiView, which supplies resort and slope names.

Moreover, Garmin claims photo voltaic charging can add as much as 5 days of battery life to “smartwatch” mode (related to your cellphone for notifications and measuring coronary heart fee, however blood oxygen monitoring is switched off, and with no exercise monitoring classes). That’s as much as 20 days versus Garmin’s 15-day estimate with out it. The estimate implies reasonably sunny situations (it may be overcast) with the watch uncovered and worn exterior for 3 hours a day.

Battery life

Corey Gaskin

Garmin’s battery life scores for the 955 vary all the way in which from eight and half hours to 110 days to empty, all due to completely different energy modes. In my utilization, I obtained about eight days of battery with blood oxygen monitoring being measured solely throughout sleep and about 10 complete hours of energy coaching monitoring. Meaning GPS wasn’t gathering knowledge as it will for a run or cycle, a doubtlessly greater battery drainer. With all-day blood oxygen monitoring enabled (one thing most individuals solely want for sleep monitoring), I solely obtained about two days of battery in the identical mode.

Once more, you aren’t getting as many energy modes on the 955 as on the Fenix and different dearer Garmin watches, however it’s fairly shut. A customizable low-power mode helps you to select which important features to maintain on when conserving the battery on this method. That would imply leaving on the heartbeat oximeter (blood oxygen monitor) whereas turning off the watch’s backlight and disconnecting it out of your cellphone. Configuration is so simple as ticking bins, and every choice exhibits roughly how a lot battery it can save you by disabling it. By Garmin’s estimates, shutting off a given setting can often present anyplace from 20 to 40 extra hours of battery life.

Recharging the 955 took slightly below 90 minutes to go from zero to 100%.

Garmin nonetheless makes the very best instruments for athletes

The Garmin 955 prices $600, however that is nonetheless a cut price attributable to every little thing it presents. The rising and bettering suite of coaching metrics alone are invaluable to athletes. No different activity-tracking firm comes near this stage of wide-ranging, detailed, and contextualized knowledge, and nobody presents knowledge so accessibly. Even a distinct segment tracker just like the Whoop Strap 4.0, which makes an attempt to evaluate and prescribe “pressure” (train/train depth), would not get s granular when explaining what space of your health you are impacting. In contrast, Oura’s Gen 3 Ring tracker does a formidable job of creating knowledge and traits accessible and straightforward to digest in-app, however it’s even lighter on coaching info, sticking to calorie burn and coronary heart fee alone for exercise monitoring.

Then you might have the Fitbits and Apple Watches. Put merely, Apple Watches are nonetheless very fundamental in what they provide to athletes. Fitbits, then again, include high quality considerations. The corporate is at present dealing with a lawsuit that alleges a few of its trackers prompted burns on customers. The opposite large draw that the 955 (and all Garmin trackers) have over Fitbit (and Oura and Whoop) is free knowledge and evaluation. It is unhappy to see subscriptions gobbling up a few of the latest and most fascinating coaching options on platforms like Oura, Whoop, and Fitbit. That is one thing Garmin says you may by no means have to fret about. If that is still the case and Garmin continues to refine, increase, and innovate its coaching instruments (because it did with the Forerunner 955), the corporate will stay atop the health totem pole.
