Suunto Race 3S: The Ultimate Lightweight Trail Running Companion with AI Coaching
The Suunto Race 3S is a compact sports watch primarily designed for trail runners and individuals training in demanding outdoor environments. This new iteration promises a brighter display, durable sapphire glass, extended battery life with precise GPS, and an innovative AI-powered training assistant. Let’s delve into what this new release offers and its estimated pricing.
What’s New in the Suunto Race 3S?
The Suunto Race 3S serves as the direct successor to the Race S, but it represents a significantly refined and enhanced model. While retaining a compact 46mm case diameter and a lightweight build of approximately 56 grams (2 ounces) with a silicone strap, the watch now boasts a premium titanium bezel, scratch-resistant sapphire glass, and a new Apollo 510 processor. This powerful processor is engineered to accelerate map rendering and menu navigation, providing a smoother user experience.
Revolutionary Display
The most striking improvement is undoubtedly the display. The 1.32-inch LTPS Hybrid AMOLED panel features a sharp 466 × 466-pixel resolution and achieves an impressive brightness of 2000 nits. This is more than three times brighter than its predecessor, the Race S. Such high brightness ensures that data readability is significantly enhanced, even when running under bright, direct sunlight.
Enhanced Battery Life and Outdoor Navigation
Suunto has made substantial strides in battery performance, crucial for outdoor athletes. The company states that the Suunto Race 3S can operate for up to 38 hours in dual-band GPS mode, which translates to approximately 40 percent longer battery life than its predecessor. For everyday use, the smartwatch mode offers up to 12 days of power, and with the always-on display activated, it can last up to 32 hours. For a dedicated runner, this provides sufficient energy reserves for most ultramarathons up to around 100 kilometers (62 miles).
Advanced Navigation Features
The Race 3S comes equipped with free, global offline maps, eliminating the need for additional subscriptions. New enhancements include the display of elevation lines and place names, providing richer navigational detail. A notable feature is Climb Guidance, which proactively informs users about upcoming ascents and descents, helping athletes strategically manage their energy on challenging routes.
The watch supports over 100 sport modes, covering a wide range of activities such as running, cycling, swimming, strength training, and various multisport disciplines. With 64 GB of internal storage, users can store maps, custom routes, comprehensive training data, and even music directly on the watch.

The Biggest Innovation: Suunto AI Coach
A significant new offering coinciding with the watch’s release is the Suunto AI Coach. This intelligent assistant operates within the mobile application, rather than directly on the watch itself. The AI Coach analyzes user data, provides answers to training-related questions, and generates personalized training plans, exercises, and routes that can be seamlessly transferred to the Suunto Race 3S.
Availability of AI Coach
Purchasers of the Race 3S will receive three months of complimentary access to the AI Coach. To qualify, users must pair their watch with the mobile application and activate the service by December 31, 2026. After this initial period, the feature is expected to become a paid subscription service, though Suunto has not yet announced its pricing structure.
Pricing and Availability
The Suunto Race 3S was launched on October 15, 2026, with a retail price of approximately 2199 Polish Zloty (PLN), which converts to approximately $550 USD (prices may vary by region and exchange rate). Suunto has made the watch available in three distinct color variations: Titanium Black, Titanium Orchid, and Titanium Feather.
