Best running watch for runners, triathletes, gym workouts and fitness

Smart watches - and smartwatches - with GPS, heart rate tracking and all the metrics you need to both run like a pro and prove it, via graphs

Whether you're going from couch to 5km, training for your first half marathon or planning on going the full marathon distance, a GPS running watch can seriously help you improve your performance. 

They're a real step up from most fitness trackers, which tend to be more about tracking steps walked and hours slept, neither of which are going to exactly push you to Olympian heights.

All of these watches pack GPS, for accurate tracking of your run distance and speed, and all either have heart-rate monitors built in, or allow you to pair an external one.

From the Garmin Forerunner series to watches from Polar, Suunto and TomTom, these running and fitness watches put all your vital stats right where you can see them. Everything from pace and distance to heart rate, cadence and even altitude are made easily accessible to help you fine tune you run whilst you're on the move.

A lot of them are also suitable for tracking your prowess in the gym, using the heart rate monitoring to help estimate how many calories you've shed. Some also have modes for cycling, hiking and general working out.

Our favourite running watch

Our favourite running watch at present is the Garmin Forerunner 630. This is a watch that's versatile enough for runners of all abilities, powerful enough to satisfy stat-hungry semi-pros, but isn't ridiculously pricey.

The 630 does NOT include a built-in pulse reader. That's actually another reason it's our #1: although wrist-mounted heart rate tracking is more convenient, and by no means a bad thing, strap-on, chest mounted heart-rate monitors are still our preferred choice for accuracy and reliability.

Garmin makes more running watches than anyone else and, in our opinion, the best of them are the finest running watches you can buy.

However, its by no means the only game in town, with TomTom, Polar, Suunto et al offering rival products of comparable quality, at different price points.


GPS Running Watch vs Smartphone Running Apps

There are plenty of excellent smartphone running apps like Nike+ Running and Endomondo, and we'd advise beginners to start with them. 

However, there's a real benefit to having your real-time stats where you can keep an eye them during your run, which is where watches come in. 

Using a smartwatch as a dedicated running watch is still not as satisfying as it should be. 

The latest Apple/Nike collaboration is the best smartwatch option so far, but even though it's a cool device, the absence of sensors such as a barometer and the fact that the Nike+ app is more about motivation than stat-tracking mean it's still a bit of an outlier in this field. The short battery life is also irksome.

Apps for stats and analysis

Almost all of these watches sync with a mobile app and online tracking tools on desktop. These let you dig deeper into the details, create and download pre-planned coaching lessons and set up goal-specific training plans to help you achieve your running and fitness goals.

Prices vary, with some coming in at under £100, though if you're looking for something from the top drawer, expect to spend north of £200. Certain of Garmin's seemingly endless stream of Fenix 3 variants can set you back over a grand, if you're feeling flash.


These are our favourite running watches, starting with our pick of the bunch, the Garmin Forerunner 630. The remainder are roughly in order but we've also indicated what type of runner each one is 'best for'. 

1. Garmin Forerunner 630: The best

A bonanza of running metrics, underpinned by rock solid exercise-tracking basics

Exhaustive running metrics
Superb build
Strong battery life
Touchscreen response is poor

Simply the best running watch available right now, the Garmin Forerunner 630 does it all. 

Despite being both light and slender, it crams in more running smarts than even a pro could manage to exhaust. 

In conjunction with a heart rate chest strap and built-in motion sensors, the 630 can track cadence, vertical oscillation, VO2 max, lactate threshold, recovery times and more. All that outputs to the comprehensive Garmin Connect app meaning running data is actually useful to help make improvements both for beginners and incrementally for those pushing their limits at the top end. 

A wealth of apps in the Garmin Connect IQ store let you adapt the watch to suit your needs, like having a quick marathon finish time figure on screen, a flashlight display, different watch faces, and apps for other sports, notably cycling.

The basics that Garmin’s known for are also present and correct: fast GPS acquisition and accurate tracking, so-so smartphone notifications, live tracking sharing, excellent battery performance, more basic step-counting type stuff, and a clear display with easy to navigate menus. 

As a touchscreen, it's rather lacking, but there are buttons too, and that's the only notable black mark against the 630.

2. TomTom Spark 3 Cardio + Music: Best value for money

Putting GPS, HR and a music player on your wrist, this is a bang-up bargain

A lot of wearable for your wonga
Handy music player
Convenient, mainly accurate wrist HR
Strong battery life
App and depth of analysis can't compare with Garmin
No notifications

Some of you may find the depth of the 630 actually goes beyond what you need. For you, sir or madam, the Spark 3 Cardio + Music might be a better choice.

That is particularly true if you like to run free of any encumbrance; naked as God intended. 

As the name of the device makes obvious, this variant of the Spark 3 (there are several others) has a heart rate tracker built in, and also a music player. So you have no need of either a chest strap or a phone as you gallop.

The HR tracking is about as good as it gets, outside of the likes of the much chunkier Microsoft Band 2 and the somewhat pricier Apple Watch 2.

Despite the extras, battery life is still decent as well, with a good 11 hours of GPS tracking and at least a week without (you can use it as a step/sleep tracker, although given how ugly it is, maybe not). Unfortunately since it’s made to be apart from the phone it doesn’t offer notifications. 

Outdoorspersons will also enjoy the addition of a compass, which means you can now track routes,  follow waypoints easily, and then find your way back.



3. Suunto Spartan Sport: Best all-rounder

THIS… IS… SPARTAN!

Great design and build
Fast GPS lock and good accuracy
Numerous sports tracked
Limited app
Quite pricey

Say goodbye to the Ambit range and hello to the Spartan line-up from Suunto. Specifically the Suunto Spartan Sport which aims to up the GPS watch design quality while still offering superb tracking accuracy and the Movescount platform, which lets you plan your training, then uses vibrating alerts to keep you at the right pace and pulse rate, and covering the distances you want. 

The Spartan Sport has over 80 sports programmed-in ready for tracking, from the usual running, cycling and swimming to yoga and even cheerleading – hoorah, at last. The emphasis is very much on outdoor activity, but you can use it in the gym too.

There’s no built-in pulse tracking on this model (a more expensive version adds HR), but that's fine. 

With good looks (by running watch standards), decent battery life (up to 26 hours), daily activity tracking and smartphone notifications make this a strong, day-to-day option.

=4. Microsoft Band 2: Best hybrid fitness device

Feels like crap, actually works really well

Handy interval training mode
Very versatile
Uncomfortable and ugly
Mediocre battery life

Microsoft's Band 2 is a  very underrated device. That's largely because it's quite unattractive, can be uncomfortable to wear, due to a strap design that has more in common with a handcuff than a watch, and looks like a bog standard fitness band rather than a watch.

In actual fact, the Band 2 is a very powerful and versatile device. 

It's packed with sensors – GPS, temperature, heart-rate, barometer and more – functions as a smartwatch in terms of notifications, tracks runs and cycle rides, and even guides you through interval workouts by vibrating at set times. The MS Band app is also surprisingly insightful.

Arguably, the Band 2 does too much, and it was quite poorly marketed and over-priced at launch, which led to it getting a slightly iffy reputation. 

However, it's really an excellent wearable for gym-goers, cross-trainers and semi-regular runners and riders, as long as you can live with its foibles. 

As Microsoft has bowed to the inevitable and stopped making it, the price must presumably come right down soon, too.

=4. Apple Watch Nike+: Best smartwatch for running

Sporty version of the Watch 2 ticks many boxes

Great design and display
Full smartwatch functionality
Excellent Nike+ app/social platform
Expensive
Poor battery life
Iffy tracking accuracy

Apple's already compelling second-gen smartwatch has GPS as well as a surprisingly accurate heart rate sensor. Now, this Nike+ edition adds a fancy-looking strap and 'exclusive watch faces', to boot.

The display is large, clear and colourful, fitness apps start at the touch of the screen and at-a-glance metrics like pace, speed and distance are super easy to see even when on the move. 

While this does have the GPS and heart rate tracking to make this a proper running watch it appears that GPS is only pinged every 10 seconds, as opposed to the usual five or six, meaning less accuracy. Unless you pair it with your phone, of course, but many don't like carrying a mobile on runs.

The range of metrics tracked can't match more serious devices such as Garmin's, but Nike's social platform is a great motivator, and for daily activity tracking, smartphone interaction and apps, nothing else here can match.

Battery life is rather disappointing as a result, mind: you'll have to charge this daily, with eight hours of tracking, tops. 

Oh, and we can confirm that of the 'exclusive' elements of the Nike+ edition (it's identical to Watch 2 Sport in every other way), the strap is excellent and the watch faces are, you know, fine.

6. Garmin Forerunner 235: Best Garmin with HR

If you must have an all-in-one, pick this over the Forerunner 630

Empty List
Empty List

The Garmin Forerunner 235 is a GPS running watch with built-in heart rate monitoring. It's still a very good mid-range option for people who want more than just pace, distance and time but aren't quite looking for the more elite level insights that come with the likes of the Forerunner 630.

GPS finds your location quickly, while an accelerometer takes care of distance and pace when you're on an indoor track or treadmill.

The optical heart rate sensor powers the colourful heart rate zone training display, as well as tracking your resting heart rate. Like all wrist HR monitors, it's not perfect, probably a bit less accurate and consistent than TomTom's, but still generally usable.

For those who want to delve a little deeper into the fitness, training and run performance data, there's a handy VO2 Max estimator that keeps tabs on your fitness levels, a recovery advisor that tells you how long to rest before your next workout and a race predictor to give you an idea of how long that 10km, half or full marathon is going to take based on your recent run stats.

All-day step counting, activity tracking and calorie burn counting is also handled. The Garmin Connect app remains a mix of impressive depth, undermined by slightly eccentric design.

The 11 hours of battery life in GPS mode with HR monitoring isn't bad at all.

7. Suunto Ambit3 Vertical: Best for hill runners

Chunktastic outdoor explorer's essential

Hefty build
Long battery life
Not the sexiest thing
Less useful for urban runs

A multi-sport GPS watch for runners with a particular fondness for slopes, the Ambit3 Vertical is designed to help you plan and track how much altitude you've conquered. 

It's probably a tad over-engineered for most runners' needs, but if you have a need to track runs over hilly terrain regularly, it's great.

The Ambit3 Vertical uses an altimeter to monitor the elevation gain of individual runs with the option to follow the altitude profile of your route while working your way up mountains. You can then keep track of your total vertical gain over the weeks, months and up to a year.

For those of like to combine running with cycling and swimming, there's the option to log multiple sports in one session and the partner Suunto chest strap can, unusually, track your BPM in the water.

As with the other Suunto watches, you can plan your training with the Suunto Movescount app, with vibrating alerts helping guide you hit the right pace, beats and distances during your workouts. 

With a battery life of 15 hours, the hills will be alive with the sound of panting for quite some time.

8. Polar M600: Best Android Wear running watch

A canny hybrid of purist's training watch, with Android extras aboard

Android Wear apps
Music and HR tracking built in
Ugly as hell
Small screen

The Polar M400 blurred the lines between activity tracker and GPS running watch and now the M600 has arrived to further combine categories by adding Android Wear, to make it part smartwatch, part running watch.

What’s great here is that this is a GPS watch first, featuring Polar's own dedicated fitness app and a swim-friendly IP68 waterproofing. Android Wear then adds the backing of third-party smartwatch apps. 

Because it's a smartwatch, it also supports music, via Bluetooth headphones, for phone-free training. 

Even better, the battery usually lasts a whole week even with run tracking. 

We're not massive fans of Polar's app when it comes to analysing stats, and it's not an attractive thing by any means, but as a daily running watch, this is still a winner.

9. Garmin Forerunner 920XT: Best for triathletes

Specialist device for three-way exercisers

Everything a triathlete needs
Comfortable design
Rather complex

Built for triathletes and those who like to mix up their workouts, the Garmin 920XT provides specific features to cater for running, swimming and cycling.

This includes everything from keeping track of your swim metrics and elevation, to showing speed and distance when biking, to a vibrating alert to let you know it's time to eat when you're running. 

The wristband is comfortable, the display easy on the eyes and Virtual Racer tech adds in an element of competition.

This is a few years old, but still among the best fitness wearables you can buy, letting the hardcore dive deep into every imaginable fitness stat, including VO2 Max. For more casual users, it's over-specced and over-complex.

10. Fitbit Surge: Best Fitbit for runners

GPS running and HR tracking on top of Fitbit's superb general fitness app and platform

Great app
Good battery life
Cheap and easy to use
More a step counter with knobs on than a running watch
Very ugly indeed
Fitbits never seem terribly accurate

When activity trackers cross the line into the world of GPS sports watches, you get Fitbit Surge. 

As a fitness tracker, this is a poor relation to the all-conquering Fitbit Charge 2 and Fitbit Blaze. However, it's the only Fitbit we'd recommend for runners because, unlike those devices, it's got GPS built in. 

It also offers built-in heart rate tracking, albeit not as good as the Charge 2's, and tracks activities, multiple sports and sleep. 

Perhaps best of all, it will automatically recognise when you're running and cycling, and start tracking, without you needing to hit start and stop. 

This isn't a totally unalloyed blessing though. Although it knows you are running, and starts using your pulse to calculate calories burned, for whatever reason, it doesn't switch on GPS, relying instead on the built in step counter to calculate - usually wrongly - distance and speed.

The battery will give you a 10-hour GPS training session or a week of standby use including plenty of smartphone notification updates and activity tracking. 

Unlike all other Fitbits, the Surge's screen is always on, so you can see what your pulse, distance, speed etc are at a glance. The down side of that is the screen is a bit on the gloomy side.  

The Surge is more affordable than a lot of the competition, and for those who aren't too fussed about in-depth metrics, it offers good value for money.

11. Garmin Fenix 3 Chronos: Best blow-the-budget watch

High-price, high-spec watch-cum-running-watch

Numerous activities tracked
Unusually smart looking
Screen unjustifiably poor for the price
…And the price is high

Their are numerous versions of the Fenix 3, with prices going from premium to, in this case, faintly ridiculous. 

We are big fans of the range as a whole. It's designed to be worn all day and look as good in a meeting as on the roads or at they gym. 

Tracking is offered for dozens of different activities, from hiking to stand-up paddle boarding, and there's built-in heart-rate tracking, although we found it to be at the lower end of the reliability and accuracy scale.

Although it's a handsome beast from a distance, the problem with the Fenix 3 is that the quality of the screen totally fails to match the comparatively opulent feel (and high price) of the rest of the watch. 

The transflective display is easy to read and gives a decent, week-long battery life, but it certainly does not say "I paid anything up to £1,000 for this thing". That's particularly true when you're just using it as a watch, as the faces are low-res and uninspired.
