The Suunto Race 3S smartwatch arrives with upgraded features to make it even better for trail running, including a brighter 2000-nit AMOLED display, more durable sapphire crystal glass, and longer runtimes with GPS navigation using free topo maps.

The Suunto Race 3S has arrived as an upgrade to the 2023 Suunto Race smartwatch (sold here on Amazon) for trail running enthusiasts looking for a durable, multi-day smartwatch. A 45 mm (1.77 in.) titanium bezel and sapphire glass help protect its brighter 2000-nit, 1.32-inch (33.5 mm) AMOLED display with a resolution of 466 x 466 pixels. The watch is powered by a silicon-carbon anode lithium-ion battery, with up to 38 hours of rated runtime when using dual-band GPS navigation or up to 12 days in normal timekeeping mode.

A faster Apollo 510 processor is coupled with 64 GB of storage for offline music, race data, and maps. The Race 3S comes with access to free worldwide topographical maps, freeing owners from the additional cost and hassle of locating and loading maps for their runs. This is similar to Garmin smartwatches like the Fenix 9 Pro (sold here on Amazon), which also offer free offline global maps.

The smartwatch comes with over a hundred sports modes, with interval training and adaptive guidance thanks to the Suunto Coach AI. The watch can help plan runs with consideration of the route, weather, and target pace in mind, with alerts during runs for upcoming slopes.

The Suunto Race 3S smartwatch comes with six LEDs and four photodetectors to monitor health.
