The Garmin Forerunner 70 is positioned as a running-focused smartwatch and successor to the Forerunner 55. Priced at £219.99 / $249.99, it offers significant upgrades in screen technology and software compared to its predecessor, though this comes with a higher cost.
The watch targets runners starting their journey but also includes enough features for seasoned runners without the high cost of pricier Forerunner models. A month of testing was conducted to evaluate the device’s performance and overall value.
Physically, it features a compact 42.6mm case weighing just 40g, making it ideal for running and comfortable all day. The design is available in playful colors such as Citron, Soft Pink, and Tidal Blue, giving it an active look. Despite its small size, Garmin retained five physical buttons around the casing. Complementing these is a 1.2-inch AMOLED touchscreen, which provides responsive navigation and punchy colors.
The screen represents a major advance from the Forerunner 55. Key features include adjustable brightness for outdoor visibility and an always-on display option. The watch is also waterproof to 50 metres, allowing use in swimming or the sea.
In terms of software, the Forerunner 70 sees a revamp over its older model. It now grants full access to Garmin’s Connect IQ Store, enabling users to download apps, data fields, watch faces, and extensions—a capability limited only to watch faces on the Forerunner 55.
The interface is described as intuitive and well-optimized for the small display, making tasks like checking notifications or controlling music straightforward. However, users should note inconsistencies between iOS and Android systems; currently, only Android users can reply to notifications.
Notable new functions include Garmin’s morning and afternoon reports, which provide daily summaries of key data, weather updates, and training reminders. Conversely, the watch omits certain features found on more expensive models, specifically NFC payments, a built-in music player, and call making ability.
For fitness tracking, the Forerunner 70 is strong, although it does not use Garmin’s most advanced hardware. It employs a multi-GNSS sensor setup rather than multiband GPS. Nevertheless, real-world testing found its GPS accuracy to be very good. The watch supports over 80 sports modes, covering activities like running, cycling, and hiking with breadcrumb navigation. However, it lacks open water swim tracking and dedicated multisport or triathlon modes.
Daily metrics are robust, offering sleep monitoring and step counts that align closely with trackers like the Apple Watch and Oura Ring 5. Heart rate monitoring is reliable during workouts and throughout the day. For enhanced accuracy, the device can be paired with external heart rate monitors via Bluetooth.
A significant improvement lies in advanced training features previously reserved for premium Garmin watches. The watch now includes Training Readiness, a score based on sleep and workout history to guide whether the user should push or rest. It also integrates with Garmin’s Coach platform to suggest running workouts based on intensity, providing structured training options.
Battery life is cited as a highlight. It promises up to 13 days in smartwatch mode and 5 days with the always-on display. The reviewer found it could comfortably last over a week without the always-on feature, though regular GPS use reduced this lifespan to approximately 4 days. Charging is done via Garmin’s proprietary cable.
The Forerunner 70 concludes as a great running smartwatch that offers reliable tracking and useful training insights in a lightweight package, making it an excellent value choice for runners. However, its significant price jump from the Forerunner 55 and the absence of certain smart features means it may not suit those seeking Garmin’s most comprehensive experience.
