The Garmin Fenix 6 is the middle child of the new Fenix family. It's the version of the outdoor watch that we imagine current Fenix owners, or those on the hunt for a new sports watch, will be casting an eye over first.
Sitting in between the Fenix 6S and the hulking Fenix 6X, the 6 gives you pretty much all of the same features in a 47mm frame. It's pretty much the amalgamation of all the best features from the full range of Garmin watches.
You can track runs, hikes, rounds of golf and even your time on the slopes. Mapping and navigation features will keep you on the right track when you're out adventuring, and you've got plenty of battery life to keep you away from that charger for weeks or even months.
There's a whole lot going on with the new Fenix, but is it enough to make it the go-to watch for outdoor lovers?

Garmin Fenix 6: Design and interface
The Fenix 6 isn‚Äôt too much of a break from the overall design language of the range ‚Äď but it has been improved in nearly every way. Whether you go regular or pro, it‚Äôs lighter than the Fenix 5, coming in at 72g rather than 85g ‚Äď so a significant saving‚Äôs been made.
The buttons feel subtly more premium too, and at last the Fenix 6 doesn‚Äôt feel like a beast on the wrist and will suit a variety of wrist sizes and shapes.
The screen is still the transflective LCD, which helps keep battery life to a maximum, but it‚Äôs been given a boost to 260x260 pixels (previously 240x240) and it does show. Visuals are noticeably crisper ‚Äď aided by a slight boost in screen size too.
Away from the hardware, Garmin has been making improvements on the operating system front that will change the way you interact with the Fenix 6. In a good way. The menus have been given a lick of paint making them more useful than before.
Scrolling down through your daily data offers more of an overview, so instead of cycling through single screens for every metric (training status, weather, calendar, heart data), they're presented as a list so information is more glanceable.
You can still dive into each segment by hitting the main button, and these menus have also been given an overhaul to show data better. If you want to customize what's displayed here too, you do have that option as well.
Garmin has sought to make the Fenix a nicer, more comfortable watch to wear all day and we think it's certainly achieved that.
Garmin Fenix 6: Mapping and navigation
TOPO mapping is a major feature of the Fenix range, and while it‚Äôs been given some new themes on the Fenix 6 (high contrast, popularity, marine, dark, and outdoor), it‚Äôs still lacking as a proper mapping experience.

When out on an activity you can navigate to a map of your surroundings, to add a little context to what‚Äôs around you. It‚Äôs basic stuff though, which shows major trails and roads, but doesn‚Äôt have the full detail of an Ordnance Survey map, and isn‚Äôt too helpful when really off the beaten track.
The pictures show us trail running in deepest Devon, with the path missing from the mapping. In fact, according to the Fenix 6 we were lost within a sea of white with no hope of escape.
In addition, zooming in and out is a painful experience on the watch, requiring a combination of button bashing not witnessed since entering Mega Drive cheat codes. There‚Äôs no pinch and zoom as the Fenix isn‚Äôt touchscreen, so having a quick zoom out requires serious effort.
If you‚Äôre mapping yourself via a GPX, it does make the experience a lot better, but it‚Äôs one that ironically works better with the sprawl of roads in built up areas, rather than out in the wilderness. Where previously we‚Äôve struggled to navigate through cities using GPS waypoints, that‚Äôs improved immeasurably by the mapping.
You can navigate to points of interest, hospitals and other landmarks using the built-in mapping ‚Äď but we‚Äôve never had cause to do that.
In short, the mapping is still a feature that sets the Fenix range way above rivals, but it‚Äôs far from an experience that we‚Äôd rely on without maps.me or an OS map in our pocket.
Garmin Fenix 6: Running
The great thing about the Fenix is that it puts everything you get from Garmin's Forerunner watch range into a more durable and robust design. The big difference between something like the Fenix and Garmin's top end Forerunner has been the difference in size. But that difference in stature is not as extreme as it once was.
While the Fenix 6 still looks bigger than wearing a Forerunner 945, it has a far more compact feel than the Fenix 5 Plus or the 3. It's comfortable to run with too and the screen is the ideal size and resolution to review your run data in real-time.
Sample run data from Garmin Fenix 6
When it comes to tracking a run, it's all going to feel very familiar. Press that top right button, select Run, wait for that GPS signal bar to go green and then get moving. There's plenty going on in the training settings too, letting you select power modes, choose a training session or switch on the navigation to make use of the Fenix 6's mapping features.
Data fields are all customizable and there's now room for more. If you want to fill that screen with running metrics, you have the ability to do that. You still get the option of richer running metrics if you're willing to invest in Garmin's Running Dynamics Pod or a footpod like Stryd.
On the whole it's still a great experience running with this Fenix, indoors or outdoors. There's plenty in terms of the metrics you can pore over and GPS signal pick-up is nice and speedy. If you're buying the Fenix to be your primary running watch, you're not going to be disappointed.
Garmin Fenix 6: PacePro
To add to its run tracking prowess, Garmin is introducing something it's calling PacePro racing strategies. If you do a lot of racing or you're keen to see if you can get faster, this is a feature for you.
Essential reading: An in-depth guide to using Garmin PacePro
Its a feature unique to the Fenix 6 range and Garmin's high-end Marq watches. The plan is to bring it to some Forerunners too, but right now these are the Garmin watches that support it.
PacePro involves offering you guidance on your pace on your watch during a run in real-time, based on your elevation data and ideal pace strategy. You also have the ability to customize data fields based on your desired uphill effort and negative split preferences.
To get it all set up you'll need to head to the Garmin Connect app, then to the Training section where you'll find the appropriate menu screen. From there you can create your PacePro strategy based on an existing course or a race distance.
In our test, we had the opportunity to test it in a race environment so took the option to select an existing course, which are currently user generated course profiles. The immediate problem we found is that many of these user generated courses are not from the most recent versions of races, so may not account for the most recent course profile.
You can select your goal time and goal pace and adjust pacing strategy ‚Äď whether you want to keep a consistent pace throughout or finish quicker and with negative splits. You can also define how hard you want to be working on the hilly parts of the course.

Once you've created your strategy and synced it to the watch, you'll be able to select the strategy from the settings in the run tracking profile. During a race, turns in the course will be pointed out to you on the watch and a + or - sign against your time will let you know whether you're sticking to your target pace. You can still access the standard running watch data fields by hitting those physical buttons on the side.
On the whole, PacePro worked really well. It takes you away from thinking about your time and more about thinking about your running. But it's not perfect. In our test, the two-year old user generated course didn't match the latest version of the course so pointed out turns that didn't exist. That meant adding a good few minutes onto our strategy, which mentally was hard to digest.
By the time we crossed the finish line, it had managed to level itself out and the strategy pretty much panned out as planned.
As an alternative to racing based on heart rate or even power, Garmin has managed to come up with a pace-based strategy that on the whole works really well, and is one we'll be taking advantage of again.
Garmin Fenix 6: Hiking
In terms of hiking tracking, there‚Äôs not too much new over the Fenix 5. Fire up a hike and you‚Äôll get data tracked: distance, time, elevation, calories. All pretty self explanatory and we found it to be accurate too.
But it‚Äôs the additional features that add to the experience.
Hiking is really where you can make use of the UltraTrac hiking features and the TOPO mapping. The Fenix 6 will also warn of incoming storms, using the barometric trend indictor. The watch uses a barometer to gauge your altitude, but a sudden drop in atmospheric pressure can indicate a storm.
ClimbPro kicks in when you start climbing, and that‚Äôs been given a mini overhaul on the Fenix 6. When it senses you ascending, a new screen kicks in that shows your vertical speed. If you‚Äôre following a pre-loaded GPX route, it will also tell you how much you have remaining and show the profile of the slope.
Garmin Fenix 6: Heart rate accuracy
The Fenix 6 houses Garmin's latest generation Elevate heart rate sensor tech, which is put to work for a whole host of things. It's harnessed for fitness tracking features like its Body Battery energy monitor, advanced sleep monitoring and stress tracking. It'll also dish out heart rate readings during the day to give you a snapshot look at your current state of fitness.

Its primary use though is for training, letting you view heart rate zones in real time, broadcast HR over ANT+ compatible devices and receive HR alerts whether you're out on a run or on your bike. It also feeds into metrics that aim to give you a better overview of your training load and and help to suggest when you're in best shape to tackle another tough session in the gym.
You do also have the ability to pair external chest straps, which can offer additional workout metrics like lactate threshold and perform HRV stress tests.
For the majority of those uses, the Fenix 6 is more than competent. Readings during the day were always in line with other wrist-based heart rate monitors we compared it to. It generally matched up with a chest strap for resting heart rate data as well.
During workouts, for an activity like running, it generally coped well with the intensity of running a hard, even tempo race where the jump up in heart rate is not as frenetic as a HIIT workout for instance.
Sample HR data from a indoor rowing session: Fenix 6 (left) and Forerunner 945 with chest strap (right)
When put to the high intensity test, we found the Fenix 6 offered a very similar experience to what we found with the Fenix 6X. It seemed to be quite slow in falling into place with the chest strap data. The sample above is from an indoor rowing session where we rowed hard for one minute, and then rested for 30 seconds throughout the workout.
While the screenshots of the workout display similar average and max heart rate readings, the story of the actual workout was very different. The Fenix 6 just seemed slower to jump up when the intensity of the workout ramped up.
The Fenix 6 seems fine for general workouts, but for anything that requires tracking heart rate where there are rapid changes in intensity (HIIT, running intervals, a spin class), you will still want to grab that external heart rate chest strap.
Garmin Fenix 6: Fitness tracking and smartwatch features
As well as being your go-to watch for the great outdoors, the Fenix 6 also wants to act as your fitness tracker and your smartwatch too. And it's giving you everything Garmin watches can offer on this front.
As a fitness tracker, you're getting basic step counting, sleep monitoring and all-day stress tracking. On top of that, you've got Garmin fitness tracker staples like its Move Bar, Body Battery energy monitor and adaptive auto step goals to offer more motivation to move and bring greater context to your data.
On the watch itself, the UI changes mean you can use the up and down physical buttons to glance at your step data and your progress towards your daily goal. Hit the physical button in the top right and you can see weekly step totals and distance covered. From within the watch settings you have the ability to add additional fitness tracking data including Body Battery, calories, floors climbed and stress.
Out of the box, the Fenix 6's fitness tracking skills are pushed into the background, but if you want them more front and center, you do have the option to do that.
Sleep tracking compared: Garmin Fenix 6 (left) and Withings Sleep bed monitor (right)
In terms of accuracy, we put it up against the step counting on the Samsung Galaxy Watch Active 2 and the Withings Move and generally found the totals to be in the same ballpark. For sleep, we generally found data like sleep duration was around the same as what the Active 2 and Withings' Sleep bed monitor dished out. Sleep breakdown graphs largely matched up too.
If you switch on the Pulse Ox sensor during sleep, you can generate richer sleep insights, though at the expense of battery life.
On the smartwatch features front, there's plenty going on here. You have the ability to read notifications and respond to them when the watch is paired to an Android phone.
You've also got Garmin Pay and a built-in music player with the ability to store up to 2,000 songs plus support for downloading offline playlists from the likes of Spotify and Deezer. Those apps can be found and downloaded from Garmin's still quite clunky Connect IQ store, where you can also find additional watch faces, data fields and other apps to bring extra functionality to the Fenix.
Day-to-day, it's the notification support that most came into play for us. They'll pop up as frequently as they do on your phone and you can control whether or not they interrupt your training sessions. Once you've negotiated your way through the setup, music features impress too, though music streaming will impact on watch battery life.
Is it as slick a smartwatch experience as an Apple Watch? We'd say probably not, but it does enough that it should satisfy those who demand proper smartwatch features.
Garmin Fenix 6: Battery life
Garmin's Fenix watches have always been well regarded for going big on battery life, giving you plenty of power for a few days or even weeks away from your charger.
The claimed Fenix 6 battery life is up to 14 days in smartwatch mode and up to 36 hours when using GPS. In maximum GPS battery mode, you can expect 72 hours. When you factor in music playback with GPS tracking, that drops down to 10 hours.
Garmin also offers an expedition GPS mode giving you up to 28 days while a battery saver mode gets you up to 48 days.
The addition of the new battery saver modes and displaying battery in days as opposed to a percentage is very telling here. As Garmin adds more features, it is going to invariably impact on battery performance. Thankfully, we didn't see any worrying drop offs in our time with the standard Fenix 6 or 6 Pro and it will on the whole live up to those claimed battery life performances.
As we've mentioned in other reviews, the addition of music streaming on Garmin's watches does impact on battery life in quite a noticeable way, so that's something to keep in mind. It certainly pays off to think about what features you'll make use of to prolong that already impressive battery life.
