One-minute review

It’s hard to stand out in a crowded field of fantastic fitness trackers, and while the Suunto Race had a lot of great ideas, its execution was ever-so-slightly off.

We awarded it 3.5 stars out of 5, finding issues primarily with heart rate tracking accuracy while noting it’s cheaper than many of its rivals despite feeling premium.

That gives the Suunto Race 2 a lay-up to be one of the best fitness trackers around, right? Fix the minor issues, and it’ll be a winner. Thankfully, Suunto has taken advantage of the legwork done by the first Race, and its successor is better in just about every way.

It looks great, performs well, and is just as intuitive for a fitness tracker newcomer as it is to someone that’s been tracking their body’s rhythms for years. With two and a half weeks of battery life and a relatively lightweight design, it’s comfortable to wear to bed for sleep tracking, too.

That does come at a cost (it’s more expensive than the original), but it’s easily one of our favorite fitness trackers of 2025 so far.

Suunto Race 2: Specifications

Suunto Race 2: Price and availability

• Two versions: Stainless Steel and Titanium
• Steel starts at £429 / $499 / AU$899
• Titanium is £529 / $599 / $999

One of the big draws of the Suunto Race was its price, but the Suunto Race 2 fixes the problems with the original Race at the cost of a higher price tag. The Stainless Steel model is more expensive, while the Titanium model ratchets the price up again.

It’s now around the price of a Garmin Forerunner 570, so hardly beyond the pale even with the increase.

Expect discounts around the usual sale seasons like Black Friday, but it’ll give Suunto Race 1 owners looking to upgrade some ‘sticker shock’, for sure.

Suunto Race 2 review: Design

• 1.5-inch display
• Feels premium to hold and wear
• Straps feel comfortable

As mentioned, there are two versions of Suunto Race 2: Stainless Steel, and Titanium. Our review unit is the former, in the Coral Orange colorway. In all honesty, three out of four of the Stainless Steel models have the same black chassis color but with different straps, while the Feather Gray is a more off-white color.

Titanium models are, again, the same chassis, but with two different color options; outside of the material choice, you’re getting the same general design throughout.

Straps attach with a pin system, which—while a little fiddly—does mean they’re more secure than other rivals. The display is 1.5 inches (slightly larger than the 1.43-inch panel on the Race 1), and is brighter, too, now up to 2,000 nits.

Two hardware buttons flank a digital crown for scrolling through menus, and the display is touch-sensitive, too, which could give it a leg-up over non-touchscreen rivals that can feel slightly less intuitive.

On the underside, there are the sensors, and the straps have gaps in them, which can make them feel more breathable than fabric-based alternatives.

There’s a pleasing weight to the Suunto Race 2. It doesn’t feel flimsy or too light, but it’s not too light where it feels cheap, either. That’s a tough balance to find, so kudos to the team at Suunto for finding a way to make it feel premium while not being too heavy to wear to bed.

Suunto Race 2: Features

• Built-in GPS
• No music storage

We’re still sad offline music streaming isn’t more common across fitness trackers, as it feels like such an obvious inclusion, but at least if you don’t need a killer playlist, you can take your Suunto Race for a run without your phone safe in the knowledge there’s GPS built in.

It’s accurate, too, doing a good job of identifying my location whether I was in busy London streets or riverside pathways closer to home. It matches up almost perfectly with my Apple Watch Ultra, which is my main tracker of choice. You can download maps for offline usage, too, something Garmin’s Instinct line doesn’t have.

There are over 115 sport modes included, too, running from the usual suspects like running and cycling, to strength training and more bespoke workouts like mountain trail runs.

Battery life is great, too. In smartwatch mode you can expect 16 days, while GPS mode reaches 55 hours - five hours more than the Suunto Run 1.

As you’d expect, it ties into the Suunto Coach app to offer detailed workout metrics beyond what’s available on the watch, and this data can be imported directly into the likes of Strava for ease of tracking and sharing with friends (and rivals).

• Features score: 4.5/5

Suunto Race 2: Performance

• Brighter display
• Faster processor
• Improved heart

We’ve already noted the improved display brightness, and that means it’s much easier to read the Suunto Race 2’s Always-On panel in direct sunlight.

Another of our issues with the last model was its clunky UI, and there’s not a whole host that’s different here aside from the fact that performance is improved thanks to a processor that Suunto reckons is twice as fast as the last generation. That makes moving through widgets much slicker on the device.

While some sleep tracking often feels binary, requiring you to trigger a specific mode (see the Apple Watch lineup), Suunto has done a great job of picking up on the occasional afternoon nap when I was feeling under the weather, as well as offering sleep stages and phase breakdowns.

Still, the elephant in the room is heart rate. Could Suunto fix the biggest issue with the Race 1? As it happens, yes, yes it could, offering similar results to those found on the Apple Watch Ultra 2, which we’ve tested against a highly accurate Polar H10 heart rate monitor and finding it the current gold standard for wrist-based heart rate measurement.

Not only that, but the Race 2 tracks heart rate variability while you’re sleeping. As someone with a heart condition, which means overnight tracking is particularly important, that’s a huge boon. Still, it only provides an average, rather than ad hoc information about your HRV.

• Performance score: 4.5/5

How we tested the Suunto Race 2

When testing the Suunto Race 2, I took it on some very light running exercises and on rucking excursions in a local, rural area.

To test its GPS, I visited London to assess its accuracy amidst larger buildings and more signal noise, and wore it regularly during the day and at night to judge the heart rate and sleep tracking.

Polar Vantage M3: One minute review

Polar has long been a trusted name in the fitness world, known for its accurate heart rate monitors, its best running watches and fitness tracking gear aimed at athletes and fitness enthusiasts. The Vantage M3 aims to deliver on that reputation, combining a stunningly bright and vibrant AMOLED display, accurate dual-band GPS and advanced health metrics like wrist-based ECG and skin temperature tracking. It’s packed with tools to help you train smarter and recover better — all for a mid-range price. Along with the Vantage V3 and the Polar Grit X2 Pro, Polar is fully embracing the transition from duller memory-in-pixel displays towards AMOLED screens.

While the Vantage M3 gets a lot right, it’s not without its faults. The setup process was painfully slow and glitchy during my testing, and the companion app, Polar Flow, feels like it’s stuck in the past despite offering lots of detailed metrics. Add to that the lack of third-party app support, and the M3 starts to feel a bit limited compared to more versatile competitors.

That said, for fitness-first users who don’t mind skipping smartwatch extras, the Vantage M3 performs generally well. The clear and sharp AMOLED display makes stats easy to read even during sunny outdoor runs. And features like Recovery Pro and Training Load Pro add meaningful insights, while dual-band GPS ensures accurate route tracking in most conditions.

While the Polar Vantage M3 is a good option for those who prioritize health and fitness tracking, it’s not the most versatile wearable out there. Its smartwatch functionality is rather lacking, as there’s no app store, voice assistant or NFC for payments. Garmin, which also offers a stripped-back training experience, at least as the Connect IQ store. In 2025, this limited functionality feels outdated, especially compared to other smartwatch options on the market right now.

Nevertheless, it’s dependable for serious fitness fans, especially for outdoor workouts which require GPS, and is packed with useful tools for training and recovery. Just don’t expect it to deliver the kind of all-in-one experience you’d get from more feature-rich alternatives like the Apple Watch or Garmin’s top-end models. If you can overlook these shortcomings and focus purely on its fitness chops, the Vantage M3 still has plenty to offer.

Polar Vantage M3: Price and availability

• Price: £349 / $399 / $599AU
• Release date: October 2024
• Colors: Night Black and Greige Sand

The Polar Vantage M3 hit shelves in October 2024, priced at $399 / £349 / AU$599, placing it in the mid-range fitness watch category. It’s available in two understated colors, Night Black and Greige Sand, which should appeal to those who prefer a minimal look.

While it’s not the cheapest option on the market, it does offer solid value when compared to Polar’s higher-end models like the Vantage V3 (£519 / $599.95 / $899AU) and Grit X2 Pro ($749.95 / £649.99 / AU$1,099.99). For its price, you get premium features like dual-band GPS, offline maps and advanced health tracking — all without stretching into the luxury price tier.

• Value score: 3.5 / 5

Polar Vantage M3: Design

• Lightweight and comfortable for all-day wear
• Stunning AMOLED display with crisp resolution
• Silicone strap is a little stiff and thus tricky to readjust

When it comes to design, the Polar Vantage M3 balances both style and practicality rather well. At just 53g including the strap, the 44mm case is lightweight enough that you’ll barely notice it’s there, whether you’re hitting the gym or dashing out to run errands. Its slim casing size means it sits snugly on your wrist, staying put even during more intense movements, so you don’t have to worry about it shifting around or coming loose mid-workout.

The stainless-steel bezel is a nice touch that gives it a more sophisticated and hard-wearing edge, and the subtle studs act as a helpful guide when you’re swiping through the touchscreen. However, the plastic body does slightly detract from the premium feel, especially compared to rivals that use more robust materials, like Garmin’s more premium models. It’s not a dealbreaker, but it does leave you wishing for a little extra polish.

Next, let’s talk about the watch’s display, which comes in a 1.28-inch AMOLED variety — easily one of the Vantage M3’s standout features. With its crisp 416x416 resolution and a peak brightness of 1,500 nits, it’s vibrant and sharp — which will be why I found it made your stats easy to read in just about any lighting conditions. That said, it is slightly smaller in size compared to some of Polar’s pricier models, which can make some data screens feel a little cramped, especially when you’re mid-workout and glancing at metrics on the go.

The display’s Gorilla Glass 3 coating also offers scratch protection, which held up well during my testing. The five physical buttons are a welcome addition alongside the touchscreen, offering an easy way to navigate menus during sweaty or gloved activities. However, they could be more tactile; Garmin’s chunkier controls, for example, feel more satisfying to use.

Nevertheless, the silicone strap is soft and comfortable overall. Its buckle-and-loop system can be fiddly at times, often needing more patience than it should to fasten securely. But on the bright side, the 22mm standard size means you can easily swap it for an alternative that better suits your needs.

• Design score: 4 / 5

Polar Vantage M3: Features

• Packed with fitness and recovery tools
• Limited smartwatch functionality leaves you wanting more

The Polar Vantage M3 is built for fitness enthusiasts, and its suite of features backs this up. From wrist-based ECG and SpO2 tracking to detailed recovery metrics like SleepWise and Training Load Pro, it’s clear to see that health and performance tracking are this watch’s primary focus. It boasts tools for just about every aspect of your fitness journey — features that work really together and delivering insights that can genuinely help you train smarter and recover better.

While the watch’s fitness features deliver, its smartwatch functionality falls short. Sure, you can read notifications and control your music, but that’s about it. There’s no app store for adding third-party tools, no voice assistant to help you navigate tasks hands-free and no NFC for payments support.

It’s surprising, especially in 2025, where even budget wearables offer more comprehensive options. And so, for anyone hoping for a more versatile device that blends fitness and day-to-day convenience, the Vantage M3 feels like it’s missing the mark somewhat.

However, the essentials are solid. Syncing the watch to the Polar Flow app allows you to view all your training metrics in one place. While the app itself isn’t the most intuitive or visually pleasing, it does get the job done — albeit with a bit of patience.

• Features score: 3 / 5

Polar Vantage M3: Performance

• Dual-band GPS is accurate but not flawless
• Metrics not quite as precise as expected
• Around five days battery life with mixed use

The Vantage M3’s dual-band GPS is a solid performer most of the time. It connects quickly and provides accurate data during runs, bike rides and hikes. However, it’s not flawless. In dense urban areas surrounded by tall buildings, the GPS can wobble slightly, deviating from your true route. It’s not a disaster by any means, but when you’re comparing it to premium models like the Garmin Fenix 8 series, for instance, the difference is quite noticeable.

Heart rate monitoring is another area where the M3 performs well, though it’s not perfect. The optical sensor offers consistent readings during steady-state workouts, but it struggles to keep up during sudden bursts of activity, such as sprints or high-intensity intervals. If you’re someone who relies heavily on accurate heart rate data for training, this might be a minor frustration. Step tracking, meanwhile, was less impressive. It often overcounted my steps by a few hundred compared to other devices I tested, which could annoy anyone who considers precise metrics as paramount.

As for battery life, it’s decent but not groundbreaking. With moderate use, Polar says you’ll get five to six days out of it, or about 24 hours in GPS mode. I found that with mixed use - tracking a workout once a day with GPS, general step counting and sleep tracking - it was just short of that, at about five days. It’s enough for most casual users, but endurance athletes might find themselves charging more often than they’d like. On the plus side, charging is relatively quick and painless, thanks to the USB-A proprietary cable included in the box.

Essentially, the Polar Vantage M3 excels as a training tool. Its recovery features, like Training Load Pro, are genuinely useful for improving your workouts, and the clear and sharp AMOLED display makes interacting with the watch nothing but a pleasure. Whether you’re mid-run in the sun or checking your progress under some intense floodlights, I found the screen performs brilliantly overall. But when you consider the price tag, it’s hard to ignore the areas where it falls short. For £349 / $399 / $599AU, you’d expect a more high-end experience, particularly when it comes to its smartwatch features. Still, if you’re looking for a fitness-first device, it’s a trustworthy option, but it’s not the standout it could have been.

How I tested

I wore the Polar Vantage M3 daily for over two weeks, testing its features during various activities, including running, cycling and yoga. I used its dual-band GPS for outdoor workouts and tracked recovery metrics with Polar’s app tools. I also evaluated its smartwatch functionality by syncing it to a smartphone, using it for notifications and assessing app integration. To test durability, I wore it during both high-intensity workouts and casual everyday use, paying attention to comfort and battery performance.
