Garmin Instinct 3 vs Samsung Galaxy Watch Ultra 2: Which is Better for Cycling? (2026)

In the world of rugged smartwatches, the battle for supremacy is fierce, and I've taken it upon myself to put two of the most prominent contenders to the test. As an avid outdoor enthusiast and tech journalist, I embarked on an 11-mile bike ride through the urban landscapes of Seattle, Washington, with the Garmin Instinct 3 and Samsung Galaxy Watch Ultra 2 as my trusty companions.

The Great Smartwatch Showdown

The journey began with a simple question: Which smartwatch is the ultimate fitness tracker for cyclists? Having previously tested these devices in the wild, I was eager to see how they fared in a city setting. With the Samsung on one wrist and the Garmin on the other, I set off on a route that showcased the best of Seattle's diverse scenery.

Tracking the Adventure

As I pedaled through bustling neighborhoods, picturesque houseboats, and towering evergreens, both smartwatches diligently recorded my journey. But the real test was in the data they captured. I was pleasantly surprised to find that both devices, along with the Strava app on my iPhone, recorded remarkably similar distances and speeds. This level of consistency is crucial for any fitness enthusiast looking to track their progress accurately.

However, a pattern emerged that caught my attention. The Samsung Galaxy Watch Ultra 2, for the third time in my testing, inflated the climb data, suggesting a higher elevation gain than the other devices. This discrepancy is intriguing, and I've reached out to Samsung for their insights. Garmin, on the other hand, provided slightly more accurate elevation data, which aligns with my expectations from previous experiences.

Heart of the Matter

One aspect that truly warmed my heart was the heart rate data. Both the Samsung and Garmin smartwatches recorded identical average and maximum heart rates during the ride. This is a testament to the advanced health-tracking capabilities of these devices, ensuring that users can monitor their cardiovascular performance with precision.

The Verdict

Despite the Samsung Galaxy Watch Ultra 2's impressive performance, I found myself leaning towards the Garmin Instinct 3. As a seasoned adventurer, I've come to rely on Garmin's reliability in various outdoor pursuits. While the Samsung watch performed admirably, the inflated climb data and my personal preference for Garmin's ecosystem swayed my decision.

What makes this comparison particularly fascinating is the subtle nuances that can influence a user's choice. Both watches offer exceptional tracking capabilities, but small differences in data accuracy and personal preferences can be the deciding factors. In my opinion, the Garmin Instinct 3's consistency and my familiarity with the brand's ecosystem make it the winner for my outdoor adventures.

As we navigate the ever-evolving landscape of wearable technology, these real-world comparisons become invaluable. They highlight the importance of not just technical specifications but also user experience and personal preferences. From my perspective, the Garmin Instinct 3 emerges as the more reliable companion for cyclists and outdoor enthusiasts alike, offering a blend of accuracy and familiarity that is hard to beat.
