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

The Great Smartwatch Showdown: Garmin vs. Samsung

In the world of fitness tracking, the battle for supremacy is fierce, and I've been on a mission to uncover the ultimate champion. This time, I pitted the Garmin Instinct 3 against the Samsung Galaxy Watch Ultra 2 in a grueling 11-mile bike ride through the urban jungle of Seattle.

The Test Course

Picture this: a bustling cityscape with a unique blend of natural beauty and tech-giant headquarters. My ride took me through a diverse landscape, from charming houseboats to towering evergreens and bustling corporate campuses. It's a route I know like the back of my hand, making it the perfect testing ground for these rugged smartwatches.

Tracking the Metrics

I strapped on both watches, each on a different wrist, and hit the road. The results were intriguing. Both devices recorded similar distances and speeds, with the Samsung edging out Garmin by a hair. But here's the twist: when it came to elevation gain, Samsung's data was noticeably inflated, a recurring theme I've observed in my previous tests with the Galaxy Watch Ultra 2.

What makes this particularly fascinating is that the Samsung watch uses the company's latest health sensor technology, while the Garmin Instinct 3 relies on the brand's next-to-latest sensor array. Despite this, the Garmin watch seemed to handle elevation data more accurately, which is crucial for outdoor enthusiasts like me who rely on precise metrics.

Heart Rate Harmony

One area where both watches shone was heart rate tracking. The average and maximum heart rates recorded by the Samsung and Garmin watches were in perfect sync, which is a huge relief for anyone who values accurate health data. This level of precision is essential for tracking fitness progress and ensuring you're pushing yourself safely.

The Verdict

While both smartwatches performed admirably, I have to give the edge to the Garmin Instinct 3. Despite Samsung's impressive features, the recurring issue with elevation data is a concern. In my experience, accuracy is paramount, especially when it comes to tracking outdoor activities. Garmin's Instinct 3 has consistently proven its reliability, making it my go-to choice for all my outdoor adventures, from hiking to snowboarding.

In the world of fitness tracking, small details can make a big difference. Personally, I'd choose the watch that consistently delivers reliable data over one with a few flashy features. While the Samsung Galaxy Watch Ultra 2 has its strengths, the Garmin Instinct 3's accuracy and proven track record make it the clear winner in my book.
