The best running watch will help elevate your training, whether you're tackling your first Couch to 5k, or trying to break your marathon record.
For beginners and experts alike, a running watch can provide valuable insight into your training and running, helping you take that next step. They'll give you metrics like heart rate, calories burned, cadence, pace, and more. Many of them even come with built-in training plans, as well as health features like readiness scores, training load, or Garmin's Body Battery.
A running watch can help you improve your performance and avoid injury and overtraining, too. There are a myriad of options, which can make choosing one quite daunting.
We've tested every running watch on the market, with experts putting them through their paces to test their battery life, comfort, functionality, and performance. We rate all of the subjects out of five for design, features, value, and performance. We collate all of that data to bring you our top picks, and you won't find any options here that we haven't tested ourselves.
As you can imagine, the best Garmins dominate our top picks, but there are also options from Apple, and new for 2025 is the excellent Garmin Instinct 3.

The quick list
You can read about each of the best running watches in our full list below, but here are the cliffnotes: a brief word on our top running watches, and who they're best suited for.
The best running watch for most people
Garmins are system-agnostic, the Forerunner is Garmin's premier running watch brand, and the 265 is reasonably priced and up-to-date. The best pick for most people, unless you want a cheap, ultra-premium, or OS-specific watch.
The best budget running watch
If you want a cheaper option than Garmin, the Coros Pace 3 is an excellent long-distance running watch, very attractively priced and bursting with features.
The best premium running watch
Ideal for outdoor adventures that demand the very best in smartwatch capabilities. With GPS, an AMOLED display, and an LED torch for attracting attention, you'll have everything you need for any trip.
The best for trail runners
The best running watch for trail runners is the excellent Instinct 3, replete with its brilliant suite of outdoor tools and super rugged design.
The best for iOS users
The Apple Watch Ultra 2 is an incremental upgrade that brings a world-leading screen to an already beautiful design. The watch retains a 36-hour battery life, which is essential if you're out a lot and using GPS at the same time.
The best cheap Garmin
The Garmin Forerunner 165 is just as reliable as the Forerunner 265, packing both basic and advanced features on a more budget-friendly level.

The best value Polar
Polar's Pacer Pro is a fantastic watch. Starting with Polar's background in heart rate tracking, the Pacer Pro is a good value mid-range option with a slick metallic finish and great GPS, even if the LCD screen is a bit bare-bones.
The best for multi-day events
The Garmin Enduro 3 is a monster of a watch with a massive 90-day battery life. In GPS mode, you can get a stonking 210 hours straight, as long as you give it three hours of sunlight a day. A bit like a houseplant.
The best Wear OS watch for runners
The Galaxy Watch Ultra is Samsung's best watch yet, with a powerful set of specs and a smorgasbord of third-party apps. We love this watch for its build quality, its outdoor-focused features, and its new programmable Quick button.
The best Fitbit for runners
Even though the Fitbit Charge 6 is out now, the Charge 5 is cheaper and better-reviewed, so it's our choice for those who want a slender fitness tracker which is GPS-enabled for advanced running metrics.
Best overall
If you enjoy running as part of triathlon training, the Garmin Forerunner 265 is a great watch for you. It's as good as the Forerunner 955 – only the fact that it's a very iterative update and shares many of the same features as its predecessors stopped it from winning an elusive five stars.
It's reasonably priced if you can't stretch to some of the more expensive entries in Garmin's stable. Its location-tracking and biometrics are extremely accurate thanks to the latest Garmin software and multi-band GPS, and it's packed with genuinely useful training tools to help you get more from your runs, bike rides, and swims.
Last year's Training Readiness score is here, and Heart Rate Variability functions allow you to more accurately tell if you're fully recovered, offering training suggestions based on how ready or how fatigued you might be. It measures how well you've recovered from the previous day's exertions, which helps you make every training run as effective as possible.
We were also particularly impressed by the full-color on-screen maps, which make navigation easy on such a display, and the sheer degree of customization on offer, especially via the new AMOLED screen. Building your own interval sessions around time or distance, for example, is surprisingly straightforward.
There are bigger, more powerful, classier-looking running watches with a broader range of sports modes and better battery lives out there, but the Forerunner 265 is a superb training aid and affordable for beginners and serious athletes alike.

Best budget watch
The Coros Pace 3, like its predecessor the Pace 2, is an outstanding running tool. At just 32g, it's barely noticeable on the wrist but includes lots of features we'd expect to find in more expensive running watches, including outstanding accuracy, workout modes tailor-made for runners and triathletes (we tested it in the pool and found stroke count accurate) and compatibility with third-party sensors like chest-strap heart rate monitors. "Running fitness" is a new composite metric that tells you everything you need to know in a single number, which is great.
At $229 / £219 / AU$399, it's the best value in the list by far when you consider longevity and amount of features for price. If you do happen to stray off the radar (in a tunnel, for example), the watch automatically calculates your cadence and stride length so you can keep monitoring your progress.
In our tests, our only complaint was that the screen was a little dim and could be tricky to read in daylight without a tap of the backlight button, which puts a small dent in its otherwise impressive battery life, but that's a small gripe.

Best premium watch
The Garmin Fenix 8 delivers all the latest hardware features, which are part of the most recent flagship running watches. One of the standouts is the new GPS software that includes "dynamic routing" - a feature that generates directions during workouts. This is ideal for those who like to deviate mid-run or mid-cycle from a pre-planned route.
The AMOLED display is another highlight of this incredible running watch. With a top-quality resolution of 454 x 454 px, this is a display that is not only beautifully bright but also incredibly clear. These are two ideal characteristics for any runner. You can choose from three different sizes as well as an additional option of a solar-powered memory-in-pixel display or a brighter AMOLED one.
Waterproofing has also been improved from version 7, with diving capabilities all the way down to 40 metres. This is a serious watch featuring hardware that goes well beyond a little dip in the sea. It also features a working dive computer for scuba activities.
Safety, especially at night, is of paramount importance, so the inclusion of an LED torch for attraction attention is a welcoming addition. It also helps with running safely at night. This is a watch that has thought of everything.

Best for trail runners
New for 2025, the Garmin Instinct 3 is a brilliant, ultra-rugged smartwatch for the great outdoors. It builds on the successful formula of the Instinct 2, delivering a bomb-proof polymer design and chunky aesthetic.
It comes in a new array of flashy colors and features improved SatIQ GPS tracking and a new LED flashlight. There's the choice of AMOLED or solar-powered MIP screens, the latter delivering marathon battery life for very long trail runs and adventures.
Under the hood, you get all of Garmin's industry-leading health and fitness tracking, including the usual massive array of running features and metrics.
Runners will get access to Garmin's daily suggested running workouts and coach experts, HR zones and alerts, recovery times, GPS-powered time, distance, and pace, running dynamics, vertical oscillation, ground contact time, stride length, power, PacePro, and beyond.
It's truly the very best Garmin has to offered packed into a rugged shell for the great outdoors, our reviewers loved it and found it stacks up to the hype in nearly every way.

Best for iOS users
If you want the ultimate Apple Watch that you can take anywhere, including into the wilderness and under the sea, then the Apple Watch Ultra 2 will be perfect for you. It's not hugely different from the first iteration of the Ultra, but the screen is Apple's brightest screen ever, which makes it perfect on those days when you're fighting to see the screen because of glare from the sun on the side of the mountain.
The refresh rate is like water falling off a duck’s back, and it’s Apple at its peak. It’s the best smartwatch screen we’ve ever seen in person from a purely technical standpoint. The new S9 SiP chip enables a range of new features including the hands-free Double Tap control. This innovative new gesture allows you to start workouts, dismiss timers, answer calls and more, all hands-free.
These small changes have made an already great watch into one of the very best on the market, which is why it also merits inclusion in our best smartwatch guide.

Best cheap Garmin
The Forerunner 165 from Garmin embraces the elements of a high-end running watch while fronting all the basic features, making it a fantastic budget-friendly running watch perfect for entry-level runners.
Most people who use running watches often rely on their wearables for extended services that can be integrated into their daily lives, and for its reasonable price tag, you'd be surprised to see that the Forerunner 165 takes that a step further. One of its most useful features is the Morning Report, a service cribbed from the 165 above, that gives you insights to your recovery process by offering workouts based on your status. That way, the watch can guide you to avoid further injury all the while ensuring to keep you moving.
Its GPS capabilities go a long way too, which during our testing, we found was accurate compared to the Garmin Epix Pro in our list below. If you're using the watch's GPS around four times a week, as we were, our test shows that its battery life can last around nine days. It's also kept the modern design of its higher-end sibling the Forerunner 265, albeit significantly lighter.

Best value Polar
The Polar Pacer Pro shares a lot of DNA with the Polar Vantage V2 and, funnily enough, other Polar devices. It's a stripped-back, super-light, runner's running watch, with no time for smartwatch frippery. It's a terrific watch and very attractively priced, but it's missing a couple of things the premium models higher on this list are packing.
The most important inclusion is Polar's advanced suite of running metrics and suggested workouts. I love this watch as it provides some excellent training recommendations, a fitness test, and all the information I could want about my run including heart rate zones, burned calories broken down minute-by-minute, detailed maps of your routes, hills you’ve climbed, and power you’ve exerted. A fitness test was introduced in previous models which gives you numerical values for your VO2 max, maximal aerobic power, and maximal aerobic speed. Repeating the test at a later date will give you a measurable indication of how your fitness is improving over time.
The Pacer Pro is lighter than the Grit X, too, and may be one of the lightest watches on this list at 41g. It doesn't feel like a plastic toy either, as so many light watches do. It doesn't contain enough memory for music, and despite packing on-board GPS and trackback features, it doesn't display maps on its watch face, providing simple (in theory) directional arrows instead, which can be fiddly to use. However, it's a great watch for the price.

Best for multi-day events
The Garmin Enduro 3 is a monstrosity. An endurance powerhouse, it builds on the Enduro 2, which already had some of the most impressive battery life we've ever seen on a watch, and adds more hours in GPS mode. Topographical maps and the new Dynamic Routing feature which allows you to go off-course and have the watch intelligently guide you back again, is incredible for endurance training. Running 30k in an unfamiliar neighborhood? Wrong turns are a thing of the past.
In general, the Enduro series gives you pretty much everything you could want to track runs. It's a tank, the Christian Bale Batmobile of fitness watches. It provides advanced fitness tracking metrics and offers sleep monitoring too. Features include a barometric altimeter, a heart rate monitor, a pulse ox monitor, 24/7 fitness tracking and smartwatch features like notifications and payments.
Its price will be prohibitive for many as it's primarily a tool for elite runners, but if you’re seeking a big watch that's a real battery powerhouse, the Enduro 2 is the one for you.

Best for Wear OS users
From a technical point of view, the Samsung Galaxy Watch Ultra is undoubtedly Samsung's best smartwatch ever. It's better than any watch they've ever produced, and that includes its build quality, size, durability, and feature set. It's even better than the Samsung Galaxy Watch 5 Pro from an outdoor workout standpoint.
The design has received a complete overhaul to make it more durable and rugged than ever. It has a thicker strap that is more hard-wearing, an outer casing that is scratch-proof thanks to its titanium material, and the watch face itself is cushioned by a squircle-style shape.
They've introduced a new button, which is orange and called the ‘Quick button’. If you think this looks remarkably like the button on the Apple Watch Ultra, then you'd be completely forgiven.
All in, this is a cracking smartwatch that stands up to its competitors with consummate ease. Its high price, relatively low battery and smartwatch-first rather than running-first approach are the only reasons it's not higher up this list.

Best Fitbit for runners
The Fitbit Charge 5 takes the best features from all of the company's other devices and rolls them into one sporty package. It's technically a tracker rather than a watch, but it packs all of Fitbit's running expertise into a single handy device, packs an AMOLED touchscreen and lasts for over a week. We think it merits inclusion.
You get onboard GPS for tracking runs, walks and bike rides without carrying your phone; an EDA (electrodermal activity) sensor to measure changes in stress levels, an ECG app, and (like the Fitbit Luxe) a bright AMOLED display that makes it a pleasure to use.
The Charge 5 is a fitness tracker built for people who are taking their workouts seriously, but want an affordable option that works as an all-around activity tracker. Less obtrusive than a "true" running watch, it still provides excellent GPS-driven metrics such as pace, cadence and speed.
The Charge 5 doesn't let you control your Spotify playlist or other music from your wrist, but that's a minor quibble, and it's an otherwise excellent fitness tracker.

How to choose
How to choose the best running watch for you
When you're picking a running watch, one of the first things to consider is your current goal. Every runner can benefit from a dedicated GPS watch, but if you're aiming to complete your first 5K, your needs will be very different to a person aiming to set a new personal best in a marathon.
For new runners, a watch that will help you set up a simple training plan and give your runs some variety are useful tools. The Garmin Forerunner 165, for example, gives workout suggestions, so you don't get stuck in the same routine, even if you're not following a specific training plan. It also suggests how long you should rest and recover after each session, so you get the most out of your training.
At the other end of the spectrum, the Polar Pacer Pro keeps tabs on your fuelling strategy for long-distance events and training sessions, letting you know when it's time to take on more carbs and water. It also works with services like TrainingPeaks, so you can download specialized plans to help you meet your next goal.
While you can use a smartwatch to track your runs, a dedicated running watch with physical buttons will always be an advantage. Not only does this allow you to control the watch without having to study the screen, but it also lets you navigate its menus, pause and start workouts while wearing gloves or with sweaty hands.
Good battery life is another important consideration. You don't want to be waiting for your watch to charge before heading out on a training session or, worse still, find that it goes flat part way through a run. Some people will only need an hour of GPS at a time, while at the more extreme end of the spectrum, others will need days.
Additional tools like music and contactless payments can also be a very useful addition, allowing you to keep yourself occupied with music or a podcast during your training and stop to pick up a bottle of water or quick snack if you aren't carrying supplies. These tools also make your running watch more practical for everyday wear, so you don't need to invest in a second smartwatch to use when you're not training.
We've factored in all these considerations when judging the watches above, so you don't have to search through specification sheets to make sure the device you're interested in checks all the right boxes.
How we test
Each time we test a running watch, we wear it for at least two weeks to ensure it gathers a full set of fitness data. Almost all modern running watches include sleep and recovery tracking, so it's essential to wear each one 24 hours a day to get the most accurate insights.
We test each watch on a pre-determined run and compare their heart rate data with figures from the best heart rate monitors and another control watch to see how they measure up. We've also put their different training tools to the test, making sure they're genuinely useful additions rather than gimmicks.
Each watch starts testing fully charged, and we record how quickly power is drained in typical use so we can compare it to the manufacturer's quoted figures. Our reviews will always tell you the features we had enabled and the type of workouts we tracked to get a good sense of battery life.
