In-depth review - Suunto Race 3s - How it performed on a 45-mile non-stop hike

After putting this watch truly through it's paces, here are our thoughts. How does the Suunto Race 3S perform on a long-distance hike? In this in-depth review, Andy from GPS Training puts the latest Suunto GPS watch through its paces on a challenging, non-stop 45-mile hike, testing its navigation, mapping, battery life, GPS accuracy and heart rate tracking. Having worn the Suunto Race 3S for nearly a week, Andy took it on the Way of Light, walking from Durham Cathedral towards Corbridge in Northumberland. With a GPX route loaded onto the watch, this was the perfect opportunity to see how the compact 56g GPS watch performed during a demanding day of navigation. Screen Visibility: Testing the bright AMOLED display in sunshine, along with gesture activation and readability on the smaller screen. Battery Life: Real-world battery performance using dual-frequency GPS, full mapping, route navigation and continuous heart rate monitoring. GPS Accuracy: Comparing distance, elevation and heart rate recordings against a Garmin Fenix watch worn on the same hike. Comfort & Usability: How the lightweight, compact design performed during a long-distance adventure. Suunto App: Exploring detailed activity statistics, mapping, elevation profiles, heart rate data, 3D route playback and GPX exports. So, how did it perform? Andy was particularly impressed with the navigation experience, the clarity of the maps and the accuracy of the recorded data. Despite the smaller screen, the watch proved easy to use throughout the hike. With an estimated 31 to 32 hours of battery life under these demanding navigation settings, the Suunto Race 3S looks to be a strong contender for long-distance walkers, hikers, trail runners and ultra-distance athletes.
