Garmin Instinct 3 vs Samsung Galaxy Watch Ultra 2: Which is the Best Cycling Smartwatch? (2026)

The Garmin Instinct 3 vs. Samsung Galaxy Watch Ultra 2: A City Cycling Showdown

In the world of fitness tracking, the battle between Garmin and Samsung rages on. The latest installment of this ongoing saga sees the Garmin Instinct 3 and Samsung Galaxy Watch Ultra 2 go head-to-head in a city cycling showdown. With the Instinct 3 on my right wrist and the Ultra 2 on my left, I embarked on an 11-mile journey through the bustling streets of Seattle, Washington. The question on my mind: which smartwatch is the more reliable fitness tracker for cyclists?

The Results: A Tightly Contested Race

The race was close, with both smartwatches performing admirably. The Instinct 3 and Ultra 2 recorded similar distances, speeds, and heart rates, with only minor discrepancies. The Ultra 2 was slightly more accurate in terms of distance, but the Instinct 3 held its own. One area where the Instinct 3 shone was in its battery usage, remaining at 5% after the ride, a testament to its efficiency.

The Climb: A Tale of Two Sensors

The real drama unfolded when it came to climb data. The Ultra 2, equipped with Samsung's latest health sensor tech, inflated its ascent data, a recurring issue in my tests. This is a concern, as it suggests potential inaccuracies in elevation tracking. In contrast, the Instinct 3, with Garmin's next-to-latest sensor array, provided more accurate climb data, a crucial factor for cyclists navigating varied terrain.

The Heart of the Matter: Heart Rate Harmony

Despite the sensor differences, the Instinct 3 and Ultra 2 agreed on one crucial metric: heart rate. My average and maximum heart rates were identical on both smartwatches, a reassuring sign of their accuracy. This harmony in heart rate data is a testament to the sophisticated algorithms and sensors that power these devices.

My Verdict: Garmin's Instinct 3 Reigns Supreme

While both smartwatches performed well, my verdict is clear: the Garmin Instinct 3 is the superior fitness tracker for cyclists. Its accurate climb data, efficient battery usage, and harmonious heart rate tracking make it a reliable companion for outdoor adventures. The Ultra 2, despite its impressive features, falls just short in terms of climb accuracy, a critical factor for cyclists.

In the ongoing Garmin vs. Samsung saga, the Instinct 3 emerges as the clear winner in this city cycling test. As an avid outdoor adventurer, I appreciate the Instinct 3's reliability and performance, making it my go-to smartwatch for logging my adventures, from the trails to the slopes to the urban jungle.

As the battle between these tech giants continues, cyclists can rest assured that they have a reliable fitness tracker in the Garmin Instinct 3, a testament to the brand's commitment to accuracy and performance.
