Suunto announced the Race 3S on October 15, 2026, as a compact trail-running GPS watch with a 1.32-inch 2,000-nit AMOLED display, sapphire crystal, worldwide offline maps and claimed dual-band GPS endurance of up to 38 hours. The 46 mm watch weighs approximately 56 g with its silicone strap and has an official US price of $599.
What the Suunto Race 3S is
The Race 3S is Suunto’s next-generation performance watch aimed particularly at trail runners, while also supporting a broad range of endurance and outdoor sports. Its 46 mm case is intended to suit smaller wrists without removing the mapping, navigation and long-duration training features expected from a full-size trail watch.

The watch combines a titanium bezel and case-back with a high-performance polymer case body and a 22 mm quick-release silicone strap. It is rated to 5 ATM for water resistance. The lens uses sapphire crystal, which is more scratch-resistant than conventional watch glass, although the manufacturer does not describe the watch as indestructible.
Display and outdoor readability
Race 3S uses a 1.32-inch LTPO AMOLED panel with 466 × 466-pixel resolution. Suunto rates peak brightness at up to 2,000 nits, a specification designed to keep pace, route and heart-rate data legible in bright outdoor conditions. Actual readability will still vary with automatic-brightness behavior, screen content, battery settings and direct sunlight.

Battery life and storage
Suunto claims up to 38 hours of battery life when using dual-band GPS and up to 12 days in smartwatch mode. Those are manufacturer figures rather than independently measured results; display brightness, navigation, sensors, music playback, temperature and GPS settings can reduce endurance in actual use.
The Apollo 510 processor is paired with 64 GB of storage for maps, routes, training data and offline music. That capacity is useful for runners who keep several regions and playlists on the watch, though the available space for each category is not stated.
Free worldwide offline maps
Offline maps are a central Race 3S feature. Maps covering locations worldwide can be downloaded through the Suunto app at no cost. They include contour lines and place names, then run directly on the watch without a mapping subscription.

- Open the Suunto app and pair the Race 3S.
- Select the map area needed for a route or trip.
- Download the map over the app before leaving coverage.
- Sync the map and route to the watch, then check that the region is available offline.
- Use the watch’s map view during the activity to follow the route and interpret terrain.
Downloading in advance matters: the free offline feature does not imply that a new area can be fetched without an internet connection. Map coverage, download time and storage use will depend on the selected region.
Climb Guidance
Climb Guidance shows upcoming ascents and descents and updates in real time. It is intended to help runners pace technical or hilly courses by showing what terrain is ahead rather than only recording elevation after the fact.
Race Planner status
Race Planner is designed to create a pacing plan from a route, weather information and a race goal. Suunto describes it as planned for a future app and firmware update, so it is not a launch feature that buyers should assume is immediately available. Availability may change.

The upgraded optical heart-rate system uses six LEDs and four photodetectors behind curved sensor glass. For deeper intensity analysis, pairing a Suunto heart-rate belt enables ZoneSense, which interprets effort from the body’s physiological response. The belt is optional; the watch’s wrist sensor operates without it.
Offline music and coaching software
Race 3S is the first model in the Race series that Suunto describes as supporting offline music playback. Users load playlists onto the watch and pair Suunto earbuds, allowing music during an activity without carrying a phone. Suunto has not stated which streaming services are supported or how many tracks fit after maps and training data are stored.

Is the Race 3S worth considering for trail running?
On specifications, Race 3S is strongest for runners who want a bright AMOLED screen, scratch-resistant sapphire, free subscription-free topo maps and a relatively light 46 mm case. The claimed 38-hour dual-band GPS figure also targets ultra-distance use, while 64 GB storage adds room for maps and music.
The main qualifications are that battery and GPS performance have not been independently validated, Race Planner is still a planned update, and the three-month AI Coach offer has activation conditions and a fixed end date. Those points should be weighed against the $599 price before purchase.
