Best Running Watches 2018: The best GPS sports watches and trackers

What is the best running watch to strap on your wrist in 2018? The best running watches reviewed

best overall running watch

Garmin Forerunner 935

The Garmin Forerunner 935 is in our minds the best overall running watch. It packs in plenty of advanced features alongside all-day and sleep tracking features. There's GPS, HRM, altimeter and a compass that combine to make it a versatile multi-sport tracker that's perfect for triathletes.


If you’re a serious runner looking for a no-compromise tracker, then the Garmin Forerunner 935 is the best overall running watch currently available and will meet even the most hardcore runner’s needs.

If you are a more casual runner or are on a stricter budget, then the Garmin Vivosmart HR Plus is the best-value option around. It packs in only the essentials but does them well.

If neither of those offerings grabs your fancy off the bat, read on to see what else 2018’s running watch scene has to offer.

Best value running watch

Garmin Vivosmart HR+

While the Vivosmart HR+ is more of a fitness tracker first and foremost, and is priced as such, it's actually a great value running watch, too. That's because it has built-in GPS and heart rate monitoring. All of the data is integrated with Garmin Connect to make it easily digestible.


How we test running watches

When testing running watches we ensure we wear them for at least a fortnight and test them against competing reference devices that have already proven to offer accurate tracking.

We also compare the wrist-based heart-rate monitor against the readings of a dedicated HRM strap to gauge accuracy. We perform all test runs on a track that we know is exactly 5km to check GPS and distance tracking.

Garmin Forerunner 935


  • So comfortable you barely notice it
  • Attractive design
  • Impressive battery life
  • Multiple training functions
  • Smartphone connectivity


  • Thick screen bezel
  • Garmin Connect app still overwhelming

The Garmin Forerunner 935 could well be the perfect running watch, with everything you might possibly want, including GPS, a heart-rate monitor and activity and sleep tracking thrown in. With its altimeter and compass it’s also a versatile multi-sport tracker, and perfect for triathlons thanks to its water-resistance.

We found the GPS superbly accurate but also quick to acquire satellite locks, meaning you’re not left waiting around before you can set off. If you are a triathlete, you can transition between disciplines with just one button press, and the menus, in general, are intuitive. Battery life is also fantastic, with around two weeks of general activity tracking or a full 24 hours of GPS use.

There’s also smartphone pairing so you can get notifications from your watch. The Garmin Forerunner 935 can be considered the result of years of product research and design and is an all-round fantastic running watch.

Garmin Vivosmart HR+

Garmin Vivosmart HR Plus


  • Rugged waterproof design
  • Five-day battery life
  • Excellent fitness tracking
  • GPS and heart-rate monitor included


  • App isn’t very intuitive
  • Not the prettiest wearable around

While the Garmin Vivosmart HR Plus includes everything you could want from a running watch, it actually more closely resembles a standard fitness tracker. Still, Garmin has somehow packed in an accelerometer, barometric altimeter, optical HRM and GPS all into its slender design. All of those sensors prove accurate, too.

Battery life, at around five days, is great and the E Ink touchscreen is easy to use even in bright sunlight. The Garmin Connect app remains a little obtuse but it does provide some genuinely useful metrics, such as its ‘intensity minutes’ measurement that gets you motivated to push harder and further.

Garmin Fenix 3 33

Garmin Fenix 3


  • Excellent battery life
  • Hard-wearing frame
  • Versatile GPS tracking
  • Quick, well-designed UI


  • Lacks golf tracking of other models
  • No on-watch maps
  • Big and bulky

While the Garmin Fenix 3 is undeniably big and bulky, Garmin has packed it full of features to appeal to hardcore fitness enthusiasts and athletes. That goes some way to justify its hefty price as well.

For starters, it supports a boggling amount of sports and disciplines beyond just running. There’s cross-country skiing, climbing, trail running and more. Activities such as Indoor Cycling will require the addition of ANT+ cadence sensors, however. You’ll also need to pick up an ANT+ HRM if you want heart rate data.

There are plenty of sensors inside, however, with an accelerometer, barometer, altimeter and GLONASS for faster location detection. You also get basic smartwatch functionality thrown in, so you can check your notifications without digging out your phone.

Garmin Forerunner 735XT

Garmin Forerunner 735XT


  • Robust design
  • Great multi-sport support
  • Good coaching and activity tracking


  • App is difficult to navigate
  • Not the best-looking watch around

The Garmin Forerunner 735XT is available as a standalone watch or as a Tri Bundle (£450), which includes Garmin’s HRM Tri and HRM Swim chest straps. Even as a standalone watch, the Forerunner 735XT has plenty of features that will appeal to seasoned athletes.

The GPS sensor is incredibly fast at picking up a signal, meaning you’re quicker to set off on a run. It’s accurate, too. Even without the use of the chest HRM straps, heart rate readings were also surprisingly accurate from the optical HRM.

Throw in great sleep tracking and the Forerunner 735XT is a solid all-rounder that’s only a little let down by its clunky Garmin Connect app that can feel overwhelming and obtuse.

Polar M400


  • Tracks GPS, heart rate and daily fitness
  • Slim and light for GPS tracking
  • Excellent features for price


  • No underwater heartrate monitoring
  • No route navigation
  • Chest belt needed for heart rate

The Polar M400 is a great introduction to running watches, providing the simplicity of a fitness band with some of the more advanced features of a dedicated running watch. It includes all the standard features, such as GPS, heart-rate monitoring (through a chest strap) and sleep tracking.

The M400 also supports a multitude of sports beyond running, including swimming and even yoga. You can also conduct a 15-minute fitness test if you’re interested in finding out your VO2 max. At the end of each run you get a Running Index score that measures you against other runners with a similar profile, so you can get a gauge on your fitness.

Battery life is also stellar and the great news is that it charges over Micro USB, so you potentially have one less cable to carry around.

Garmin Vivoactive 3

Garmin Vivoactive 3


  • Easy-to-read display
  • Accurate distance tracking
  • Good heart rate monitor
  • Long battery life


  • Feels a little plasticky
  • Limited coaching elements
  • Garmin Pay isn’t widely available
  • No onboard music storage

The Garmin Vivoactive 3 is the company’s take on a running watch with added smartwatch functionality. It includes the usual GPS and heart rate monitoring to make it a great running companion, alongside runner-centric features like VO2 Max estimations. It’s also a fully-fledged fitness tracker with all-day activity tracking and sleep tracking.

Alongside its fitness features, there are some basic smartwatch functions, too, such as notification mirroring from your smartphone and the ability to control your media. Disappointingly, there’s no onboard storage for your tunes, so you’ll still need to bring your phone along if you like music or podcasts to keep you entertained.

Otherwise, the excellent battery life will appeal to seasoned runners, especially the 13 hours of battery even when using GPS. Proper smartwatches can’t compete on that front.

Polar M600


  • Comfortable to run with
  •  Accurate GPS and HRM
  •  Water-resistant


  • Silicone strap picks up lint and fluff
  •  Poor-quality display
  •  Charging is slightly fiddly

Building on a lot of what Polar learned from the excellent Polar M800, the Polar M600 adds in Android Wear support, meaning you have a fully-loaded smartwatch as well as a fantastic running watch. The great news is that the Polar M600 is confirmed to be receiving the Android Wear 2.0 update, too, so it should get a raft of new features.

Even on Android Wear 1.5, we found it worked great. Its running tracking was also excellent thanks to accurate GPS and well-performing heart rate monitoring. The M600 works alongside Polar’s Flow app, which provides some useful training insight such as its Running Index score and Training Benefit measurements.

While the Polar M600 might not be the most attractive smartwatch around, it is first and foremost a running watch, so Android Wear is a nice bonus.

Apple Watch Series 2


  • Bright, beautiful screen
  • Great fitness tracking
  • GPS makes it more versatile
  • Solid battery life
  • Snappy performance


  • Expensive
  • Looks the same as previous version

While the Apple Watch 2 might not be the first thing you think of when it comes to a running watch, it packs in plenty of features that make it more than capable. Apple has managed to cram in a GPS sensor into the new Apple Watch while keeping its small size. The Apple Watch Series 2 will likely be less of a distraction during runs compared to some of the weightier options available.

Apple’s watchOS has better app support as well, meaning it might well be the more versatile smartwatch away from the running track, too. Apple has also made the Series 2 waterproof to 50m, which is very impressive for a smartwatch. So if you’re a triathlete it could well be the better option.

Apple also recently released watchOS 4, which improves the activity tracking with new goals as well as adding support for high-intensity interval training (HIIT) workouts. A new safety feature can also use the Apple Watch 2’s display as a safety light so you’re more visible when night running.

We compared the Apple Watch 2’s performance against some dedicated fitness trackers and running watches, and it came out impressively accurate. Be sure to have a read of our dedicated article for the full low-down as well as reading the review.

Apple Watch Series 3

Apple Watch Series 3


  • Snappier performance
  • Improved exercise tracking
  • Super-bright and clear display
  • Decent battery life (when not reliant on LTE)
  • watchOS 4 improvements
  • Apple Pay is still super useful


  • LTE has a big impact on battery life
  • Needs more dedicated watch apps to make use of LTE
  • Need to wait for Apple Music streaming
  • Siri doesn’t always work
  • No LTE roaming

The Apple Watch Series 3 has all the functionality of the aforementioned Apple Watch Series 2. Where it differs is that it’s available in GPS or GPS + LTE options. The latter will let you use your Apple Watch 3 with a truly phone-free experience, letting you still make and receive calls and texts while leaving your phone behind. You can also stream Apple Music directly through your Apple Watch 3’s LTE connection.

Other improvements include increased performance from the updated S3 chip and improved wireless performance, too. Returning features include the built-in GPS and heart rate monitor, making the Apple Watch Series 3 a seriously souped-up running companion.

TomTom Spark 3

TomTom Spark 3


  • Convenient phone-free running
  • Simple, intuitive interface
  • Compass-based trail guidance
  • Accurate heart rate monitoring


  • Design hasn’t changed much
  • No smartphone notifications
  • TomTom MySports app needs work

The Spark 3 is the third-generation of TomTom’s running watches (also available as the TomTom Runner 3, which has a slightly different strap). Like previous versions, it’s available in a wide variety of models that include a HRM or built-in storage for MP3s. The model we reviewed was the Cardio + Music, which includes both. Having an MP3 player on your wrist, paired with included Bluetooth headphones, means you can leave your smartphone behind.

One of the best new features of the Spark 3 is Route Exploration. Thanks to a new compass, the watch can trace your route, meaning you can always trace your path back to the start if you’re running in unfamiliar territory. You can also upload .GPX route files to follow pre-determined running routes. Perfect if you want to take in some specific sites along the way There’s also both cycling and swimming support and impressive battery life longevity.

Garmin Fenix 5X 31

Garmin Fenix 5X


  • Useful built-in maps
  • Excellent battery life
  • Support for lots of sports
  • Rugged and attractive


  • A bit heavy and bulky for some
  • Garmin Connect app is still overwhelming

The Fenix 5X is the biggest and most feature-packed of Garmin’s new Fenix 5 smartwatches with a price tag to match. There’s a myriad of sensors making this an impressive and flexible sports tracker. It’ll cover the more mainstream activities like running, cycling and swimming, but goes far beyond with more obscure activities like paddle boarding, as well as being a great hiking companion.

As you’d expect, it’s built to last, with a rugged sapphire screen and water-resistance to depths of 100m. The memory-in-pixel display makes it really easy to read the display even in bright sunlight, but it’s also great for the battery life.

You also get smartphone notifications from your connected device, which is always handy, making this an incredibly versatile running and sports watch for those that want an all-in-one device that’s suitable for adventurers.

Those are our top picks of the best running watches. If you want to know more about what to look out for when buying a running watch then read on.

Best Running Watches – Features you need

A built-in GPS receiver is a must-have for any serious running watch. Where basic accelerometers and gyroscopes have to estimate your distance covered, a GPS-enabled running watch will more accurately be able to show all the ground you’ve covered.

GPS can also allow you to upload .GPX routes to your sports watch, letting you follow along popular trails and routes. The TomTom Spark 3 also makes use of its GPS and built-in compass to show you the route you’ve ran on your wrist, allowing you to then find your way back to the start more easily. This is perfect if you’re often running in unfamiliar locations or have a habit of getting lost while out on your runs.

A running watch with a screen will also provide easier at-a-glance data during your run, so you can see your pace, lap times, cadence and heart rate without having to try and pull your phone out. Many general activity trackers lack a screen.

The application used to display performance data is another important consideration. Better watches and accompanying apps will let you break down your run into segments. You can then not only compare your personal bests across distance, but also against specific parts of your run. That massive hill at the start of your course you particularly dread? Now you can see you made it up there just that much faster.

More advanced running watches will also include other sensors, such as altimeters. These calculate your altitude so you can more accurately log those devastating hill sprints you’ve been working on to improve your acceleration and explosiveness.

In place of a wrist-based optical heart rate monitor (HRM), or sometimes to supplement one, most running watches will work with a separate chest-based HRM. These are far more accurate than their optical counterparts and are able to more accurately take continuous readings. This means those High-Intensity Interval Training (HIIT) sessions are tracked more accurately, both in terms of speed through GPS and also in taxation on your cardiovascular system.

As an added bonus, many running watches nowadays will include some smartwatch functionality. This can range anywhere from basic smartphone notifications so you don’t have to constantly whip your phone out, to fully-fledged app ecosystems so you can add extra functionality. Many smartwatch-specific wearables can also act as a good running watch, too, although you’ll often miss out on some of the more advanced training features of a dedicated running or sports watch.
