As Garmin leads the sport watch segment and Coros continues its ascent, Suunto is slowly carving out its niche. Initially focused on outdoor watches, the Finnish brand is now venturing into more traditional running watches.
The Suunto Run 2 is designed for performance analytics in road running and introduces a compelling feature: local mapping on the wrist, all at a price point that undercuts much of the competition. Here’s a detailed review of the Suunto Run 2.

Suunto Run 2 Design: Understated Yet Distinctive
The Suunto Run 2 targets the road running segment, from 5k events to marathons. Following the recent launch of the original Suunto Run in May 2025, it’s clear that the brand has not completely overhauled its design approach.
This model bears a strong resemblance to its predecessor, maintaining the minimalist aesthetic that defines the Finnish brand. It comes in one size, 46 mm in diameter and 11.7 mm thick, and features robust materials including a stainless-steel bezel and Gorilla Glass, enhancing scratch resistance.
The Suunto Run 2 is comfortable to wear. This is my first experience with a Suunto watch, and its design reminds me of the Coros Pace Pro and the Garmin Forerunner 570, especially with the metal surrounding the display. The watch is well-proportioned, striking a balance between bulkier trail watches and sometimes overly diminutive running watches. Weighing 53 g with the strap, it maintains a secure fit during runs.
Comparatively, the Coros Pace Pro weighs 49 g, the smaller Coros Pace 4 is 40 g, and the Garmin Forerunner 570 is 50 g.
The Suunto Run 2 comes with a standard strap system. It is initially equipped with a silicone strap, but it can be easily swapped for any 22 mm wide strap with a quick-release spring bar. The provided strap’s clasp tends to unlatch too easily without a loop, which is a minor gripe I have with the Run 2.
The watch is controlled via three buttons on the right side of the case, including a rotating crown in the middle. It lacks a microphone and speaker, aspects we’ll discuss later, and features several subtle “Suunto” branding elements, including on the strap, at the base of the case in silver, and even engraved on the left side of the case.
Finally, the Suunto Run 2 is rated at 5 ATM, meaning it can be worn in the shower, while doing the dishes, and even swimming in a pool, provided you remain at the surface.
Suunto Run 2 Display: Bright and Comfortable
One of the major updates with the Suunto Run 2 compared to its predecessor is the display. While retaining an AMOLED screen, as seen in the Suunto Vertical 2 and Race 2, this model features a significantly brighter display.
Specifically, Suunto claims this watch can reach a peak brightness of 2000 cd/m², up from 600 cd/m² in the original Suunto Run. This matches the maximum brightness of the Garmin Fenix 9, Amazfit Balance 2, and Apple Watch Series 11. For an entry-level sports watch, this ensures easy readability during training, whether at night or under bright summer sunlight.
Additionally, the watch includes an ambient light sensor, allowing it to automatically adjust the screen brightness according to your surroundings.
The Suunto Run 2 maintains the same display characteristics as the original Suunto Run, featuring a 1.32-inch diameter screen with a resolution of 466 x 466 pixels. This provides a pixel density of 353 pixels per inch, which is more than adequate for viewing without noticeable pixelation. For comparison, the “Retina” displays of the Apple Watch have a standard of 326 pixels per inch. However, the large bezels around the display, which only allows the screen to occupy 53% of the front of the watch, are a bit disappointing given the watch’s size.
Suunto also offers an “always-on” display mode, which keeps certain information visible at all times. This is not only aesthetically pleasing but also convenient for discreetly checking the time without needing to perform the obvious gesture of raising your wrist.
Additionally, you can set the watch to “sleep mode” during certain hours, such as at night. This mode automatically disables the always-on display and the gesture-based screen activation, which is helpful for preventing unwanted disturbances if you accidentally move your hand close to your eyes while sleeping.
As for watch faces, the Suunto Run 2 initially comes with a digital face that can be customized in terms of color and complications. However, Suunto’s mobile app offers nearly fifty additional watch faces for free download. You can also create your own custom face using a photo, selecting the font for the time display, and choosing the complications you want.
Suunto Run 2 Usage and Apps: Primarily a Sports Watch
Like all Suunto watches, the Run 2 is compatible with both iPhones and Android smartphones. To pair the watch with your phone, you’ll need to install the Suunto app, as expected.
Navigation through the watch’s menus is managed via the three side buttons, including the rotating crown, and the touchscreen, which recognizes the following gestures:
– Swiping up/down or rotating the crown: accesses widgets.
– Swiping left or pressing the crown: accesses sport profiles.
– Pressing the upper right button: opens the last used activity (customizable).
– Pressing the lower right button: goes back.
You can also add or customize shortcuts for the upper and lower buttons, for both short and long presses. For example, the Suunto Run 2 allows you to open the settings panel for quick adjustments with a short press on the lower button when on the watch face. You can also launch a specific app, such as heart rate tracking, weather, or the media player, by pressing and holding the upper button.
Overall, the interface is quite similar to those found on other sports watches like those from Garmin, Coros, or Suunto, based on data widgets. Since the Suunto Run 2 is the first watch from the brand that I’ve worn, I must admit that it took me some time to get used to it. For instance, to access all the preinstalled apps, you have to scroll through the list of widgets. Unfortunately, there’s no shortcut to open just the apps, which would have been more convenient.
Moreover, it’s important to note that Suunto does not offer any third-party apps, so you can’t expand the functions of the Run 2 by installing additional apps or data fields. While this is disappointing, especially since the Finnish brand offers its SuuntoPlus app store on higher-end models, you can at least receive notifications from your smartphone to be alerted to WhatsApp messages or phone calls. The watch also supports direct music storage, which you can listen to via Bluetooth-connected headphones or earphones, with 4 or 64 GB of storage available depending on the watch model.
However, since the Suunto Run 2 does not include a speaker or microphone, it cannot be used to make or receive phone calls. Similarly, it does not have a built-in flashlight and lacks an NFC chip for contactless payments.
Suunto Run 2 Sports and Health: Exceptionally Precise Data
The Suunto Run 2 is equipped with the standard array of sports watch sensors. It includes an optical heart rate sensor, an optical pulse oximeter, a gyroscope, an accelerometer, a compass, a barometric altimeter, and standalone GPS tracking. However, it does not offer an electrocardiogram feature.
GPS Accuracy of the Suunto Run 2
For location tracking during workouts, which helps to measure distance, routes, and speed, Suunto has included a chip that supports multi-GNSS (GPS, Galileo, Glonass, Beidou, and QZSS) and dual-frequency GPS.
This means that the Suunto Run 2 benefits from the best available technology for reliable GPS tracking, both on open, straight roads and in urban environments with high buildings.
To assess the reliability of the Suunto Run 2’s GPS tracking, I wore it on my left wrist during several running sessions in a park, in the city, and on an athletics track—without activating the dedicated track mode. I then compared the distances and routes to those recorded by a high-end outdoor watch, the Garmin Fenix 8.
| Runs | Garmin Fenix 8 | Suunto Run 2 | Difference |
|---|---|---|---|
| Run 1 (track) | 11.956 km | 11.980 km | +0.20% |
| Run 2 (park) | 17.117 km | 17.078 km | -0.23% |
| Run 3 (city) | 7.429 km | 7.367 km | -0.83% |
| Run 4 (park) | 8.665 km | 8.659 km | -0.07% |
| Run 5 (city) | 12.547 km | 12.564 km | +0.14% |
| Run 6 (city) | 9.595 km | 9.501 km | -0.98% |
| Run 7 (park) | 8.818 km | 8.795 km | -0.26% |
| Total | 76.127 km | 75.944 km | -0.24% |
As the distances show, the Suunto Run 2 offers very close tracking to that of the Garmin Fenix 8, with a total difference of less than 200 m over more than 75 km, which is considered marginal. The only significant differences occurred during a few city runs between the two watches.
As the comparisons show, the differences are not always to the disadvantage of the Suunto Run 2. In the city route, the Suunto watch even performs better than the Garmin Fenix 8, especially with tighter turns that are closer to the actual route taken.
Moreover, one of the main new features of the Suunto Run 2 is its mapping capability. While the original Suunto Run lacked this feature, the Run 2 allows you to display a real map background to help you navigate your route. This is useful not only for trail running or hiking but also for urban running to find the best way to reach a specific point. In the sports watch segment, except for Amazfit, few brands offer such a feature on a model priced under 300 euros.
It’s worth noting that Coros recently updated its Coros Pace 4, which is in the same price range and also targets road running, to include local mapping as well.
Heart Rate Accuracy of the Suunto Run 2
The Suunto Run 2 introduces a brand new optical heart sensor for the Finnish brand, featuring twelve channels. This not only provides a more advanced sensor than the first-generation Suunto Run but also differs from the sensors in the latest Suunto Vertical 2 and Suunto Race 2. The arrangement of the LEDs and sensors is reminiscent of Garmin’s Elevate Gen 5 sensor.
To assess the accuracy of the heart rate sensor, I wore the watch on my wrist during several running sessions. These included a steady-state run, a threshold session with long intervals, and a VMA session with short, intense pace changes.
| Heart Rate Measurement | Electrode-based Heart Rate Belt | Suunto Run 2 | Average Deviation | Average Deviation After 10 min |
|---|---|---|---|---|
| Average HR | 143 bpm | 143 bpm | -0.12% | 0.00% |
