Garmin Forerunner 70 review: a lightweight entry-level GPS sports watch

Harriet L. Whitmore • September 6, 2026 16:48

Garmin has skipped two generations of entry-level GPS sports watch to launch the Forerunner 70, five years after the previous Forerunner 55. The leap forward is chiefly software-led, drawing on algorithms and newer features already found elsewhere in the range. However, several hardware omissions hold the watch back and mean it will not suit every athlete.

Garmin introduced the Forerunner 70 alongside the Forerunner 170 on 12 May 2026. The two watches are closely related, although the Forerunner 70 offers fewer features and comes at the more competitive price of €249, which is €50 less. As its name suggests, it belongs to a line aimed primarily at runners, particularly those who run on roads.

At €249, it is more expensive than the Forerunner 55 it replaces, yet it means Garmin customers on a tighter budget no longer have to choose an older-generation watch. In that respect, the Forerunner 70 was eagerly anticipated. Still, several years have passed and competition has moved on considerably. Rival Coros has demonstrated with its Pace 4 that an entry-level GPS sports watch can remain technologically advanced without making compromises.

The sub-€300 sports-watch market has also created demand among sometimes experienced athletes. These more affordable models are lighter too, an essential consideration for running. Watches weighing only 40 grams can therefore offer the basics that matter: GPS and an accurate heart-rate sensor, a more legible AMOLED screen and formidable battery life. Is that what the new Garmin Forerunner 70 delivers?

Garmin Forerunner 70 design, build and dimensions

A 43 mm, 40-gram watch

Remaining compact and lightweight, the Garmin Forerunner 70 gains 1 mm in diameter, measuring 43 mm rather than the Forerunner 55's 42 mm. Its weight rises by 3 grams to 40 grams, but it gains a larger 1.2-inch display, up from 1.04 inches on the Forerunner 55. It also swaps transflective MIP technology for a colour AMOLED panel with a 390 x 390-pixel resolution. The display is now touch-enabled, although Garmin has also retained physical controls: there are five buttons covering every available command.

We used the watch both through the touchscreen and via its physical buttons. In the settings, touch control can be locked only during an activity to prevent unwanted inputs. That said, the AMOLED screen wakes too readily for no reason: if the watch is resting on a table, for instance, the slightest vibration can turn the screen on and unnecessarily use battery power. Otherwise, there is little to criticise about the construction: the watch is light enough and well put together.

Watch colours, materials and accessories

The Garmin Forerunner 70 comes in four colourways. Alongside standard black and white versions, there are lemon and lavender options. The black version has a yellow-tinted main button, while the remaining colours use a pale-blue main button; it is a shame that an entirely understated model is not available. The watch is supplied with a silicone strap featuring numerous adjustment holes. Other straps are sold as accessories, in different colours and materials including fabric and Milanese mesh.

The design clearly inherits elements from Garmin's more premium models. Garmin has not tried to make this watch look markedly different from its pricier alternatives. Compared with a model such as the Forerunner 570, the main difference is that the bezel is not aluminium and the whole watch is plastic. Otherwise, the essentials are present, resulting in a fairly understated and practical watch; labels around the bezel indicate the function of each physical button.

Among the other available accessories, the Garmin Forerunner 70 can be fitted with a bike mount, a power meter for cycling or running, and a heart-rate monitor offered in two versions, HRM 200 and HRM 600, and two sizes, XS-S and M-XL. The remaining options relate to the Garmin+ subscription, available with monthly or annual billing. The Forerunner 70 includes a USB-C charging cable on the plug side and Garmin's proprietary connector on the watch side, the same one used by the brand's other models.

Garmin Forerunner 70 sensors

As an entry-level Garmin sports watch designed for running, the Forerunner 70 is somewhat modestly equipped when it comes to sensors. There are positives, but also notable drawbacks. Let us start with the good points.

More accurate measurements

The new Garmin Forerunner 70 benefits from a fourth-generation optical heart-rate sensor, immediately setting it apart from the older Forerunner 55. Intended to measure and track heart rate during exercise, this sensor is more accurate and responds better to sudden changes, such as those experienced during interval training. The Forerunner 70 also gains a pulse oximeter for measuring blood oxygen saturation, or SpO2. This is useful for identifying sleep apnoea at night.

Its heart-rate readings appeared entirely consistent with measurements taken using a chest strap, which is among the most accurate types of equipment on the market. The sole caveat, and it applies more or less to every GPS sports watch at this price, is interval training: the sensor is not responsive enough to record sudden and repeated pace changes with complete accuracy.

GPS, altitude and elevation limitations

On the downside, it is immediately apparent that the Forerunner 70 does not include dual-frequency multi-GNSS. GPS tracking is therefore less accurate, which is a genuine disadvantage, as many GPS sports watches at this price include dual-frequency positioning. It is extremely useful in cities or forests for retaining accurate data. The other significant sensor omission is a barometric altimeter, which would provide altitude and elevation-gain measurements. For hiking or trail running, this information cannot be recorded by the watch, which does not include GPS altitude measurements either.

As a result, the Garmin Forerunner 70 cannot provide accurate distance figures at the end of every outing, especially when running through a city with narrow streets or in forests and mountains. Hikers and trail runners should therefore look elsewhere, as Garmin's Forerunner 70 lacks a barometric altimeter. There is no mapping either, but we will return to that in the watch features section.

Finally, the Forerunner 70 does not include NFC, meaning contactless Garmin Pay payments are unavailable. This is not a sensor that benefits sporting performance, but it is important within the Garmin range because it makes life easier for athletes, who no longer need to take a smartphone or bank card with them if they wish to pay for, say, a coffee or a transport ticket.

Watch features

Having considered these hardware limitations, it is worth looking at the new Forerunner 70's features, where it does score some points. Bear in mind, however, that every feature listed here is also available elsewhere in Garmin's Forerunner range: the FR70 remains a basic model, so none of its functions are exclusive.

For sport

Starting with sports features, the new watch can show up to 8 metrics on screen, compared with 4 on the previous Forerunner 55. Battery consumption will vary depending on whether the screen is configured to remain on constantly or wake only when the wrist is raised. However, the “Always-On” display is not fully illuminated throughout, as brightness drops after a few seconds. This is not an issue, unless the watch is being used on a bike.

Around 60 sports profiles are available, although the watch will mainly be used for running, cycling, swimming, yoga, Pilates, HIIT and strength training. More importantly, the Forerunner 70 does not offer a multisport mode, so there is no triathlon or swimrun mode. Open-water swimming is unavailable as well. The watch is consequently not recommended for triathletes or swimmers.

On the other hand, it includes Garmin's useful suite for assessing fitness level, including VO2 max, training status, HRV status, training readiness score and sleep monitoring, as well as training tools such as running power and dynamics, workout suggestions, quick workouts, training load, Garmin Coach plans and PacePro. The addition of quick workouts deserves a mention: this feature lets users create a workout directly on the watch by specifying the desired duration and session type. It is useful for beginners.

As mentioned earlier, mapping is not available on the Garmin Forerunner 70. That means you cannot head out with a route map on your wrist, unless you follow it using breadcrumb navigation with directional prompts. Competitors, including the Coros Pace 4, offer no better solution. It is useful and can help out, but it cannot replace a proper map. Even the €549 Garmin Forerunner 570 does not offer mapping; Coros provides it from €350, while Amazfit remains the leader in this area from €150.

For everyday use

Turning to everyday data and features, Garmin includes everything needed on the Forerunner 70: sleep monitoring, stress tracking, HRV status and menstrual cycle tracking, although the latter is manual. During the day, the watch can display phone notifications, weather information, calendar alerts, plus morning and evening reports. Music cannot be played from the Garmin Forerunner 70. Only the Forerunner 170 adds this capability, provided you pay for the €349 Forerunner 170 Music.

The omissions are therefore numerous, even in terms of features. Garmin need not worry about contactless payments, as it is the only brand to offer the function compared with specialist rivals such as Coros. However, a Coros Pace 4 can carry music without an additional charge. The brand has also just added an equivalent to Garmin's LiveTrack, allowing users to see in real time where loved ones recording a GPS activity are located. The Garmin Forerunner 70 does include this feature, along with Garmin Messenger.

Garmin Forerunner 70 battery life

Charged using the same proprietary cable as all other Garmin watches, the Forerunner 70 stands out for its battery life. Its lack of a barometric altimeter and dual-frequency GPS, together with its more limited feature set, means it demands fewer resources and posts highly respectable figures for a GPS sports watch. Garmin claims average battery life of 13 days in everyday use, which was very close to reality in our test. During continuous activity using GPS alone, it lasts 20 hours. In multi-GNSS mode, it offers 16 hours.

The watch will therefore comfortably last a week, or even longer if its GPS is not used to track sporting activities, such as strength training and other indoor sports. It is also important to note that battery life differs greatly depending on whether “Always-On” is enabled to keep the AMOLED screen lit. This mode can be set to activate only during activities, when a quick glance at the watch is useful. Battery life will then be around 6-8 days. With “Always-On” permanently enabled, it will be a maximum of 4 days.

Conclusion: our verdict on the Garmin Forerunner 70

Sold for €249, the Garmin Forerunner 70 fulfils its entry-level brief by replacing the ageing Forerunner 55. Customers determined to buy a Garmin can now do so without spending more than €300 or having to settle for a watch based on technology from several years ago. It offers AMOLED, good battery life and a very light build. Its new heart-rate sensor and GPS also make it more accurate.

That said, Garmin has deliberately limited the Forerunner 70. For sport, it lacks dual-frequency GPS and a barometric altimeter. For everyday use, it offers neither Garmin Pay nor music. Finally, its software does not support multisport modes such as triathlon or open-water swimming. More fully featured alternatives are available, notably from Amazfit for those wanting to practise Hyrox or gain access to a watch with built-in mapping at a low price, or from Coros for those seeking a dual-frequency GPS sports watch with an AMOLED screen and the same lightness as the Forerunner 70.

As with the Forerunner 265, Garmin is chiefly trying to steer customers towards the Forerunner 170, which costs €50 more and offers more from the watch, notably a barometric altimeter. But buyers must make another choice there too: the standard FR 170 does not include music. Once again, an additional €50 is required for the FR 170 Music.
