The Pixel Watch 5 is Google’s most accurate smartwatch ever for tracking outdoor activities. Google even benchmarked its performance against pricier wearables, including the Apple Watch Ultra 3 and Garmin Fenix 8 Pro, two of the best smartwatches available for fitness tracking, but can it really compete?
I decided to find out by strapping the Pixel Watch 5 to one wrist and the Apple Watch Ultra 3 to my other and walking seven miles around Seattle, Washington.
Google says that the latest Pixel Watch is twice as accurate at route mapping in environments with obstructed skies like “urban canyons,” so I made a point of cruising around the Emerald City’s denser neighborhoods, like South Lake Union, which is jam-packed with gleaming corporate skyscrapers.
I also made my way through several expansive parks, meandering beneath enormous canopies of old-growth trees.
So, how did the Pixel Watch 5 do? Check out the results below.
I walked 7 miles with the Apple Watch Ultra 3 vs Pixel Watch 5
Note: I split my walk into two separately tracked legs and ran Strava on my iPhone 16 Plus as a control for distance, pace, and climb.

The Pixel Watch bested the Apple Watch at tracking my distance
For distance-tracking precision, the Google Pixel Watch 5 proved slightly more capable than the Apple Watch Ultra 3 during this demo, assuming, of course, Strava’s data is correct (which it generally is).
That said, both devices did pretty well at logging my miles — well within a reasonable margin of error — but the latest Pixel Watch did just a little better.
Elevation tracking is a toss-up
Things get a little trickier when we look at elevation. For the first leg of my walk, the Apple Watch Ultra 3 proved more accurate, with a total climb tally that’s just 18 feet less than the control. Google was more generous with my uphill efforts, to a fault, logging 41 additional feet of gain compared to the control.
During the second leg of my walk, though, the Pixel Watch beat the Apple Watch with a total climb that was just 11 feet greater than Strava’s measure, compared to 24 feet over for the Ultra 3.
Both watches noted similar paces
Strava tends to log slightly quicker pace data than most modern smartwatches I test, and the same is true here, even if Strava’s data isn’t that much faster.
That said, for each of the two legs of my walk, the Apple Watch Ultra 3 and Google Pixel Watch 5 calculated remarkably similar paces, a result I love to see.
Heart rate data is also a near-match
The same is true for heart rate data: Both the Apple Watch Ultra 3 and Google Pixel Watch 5 measured strikingly similar averages and maxes during each of the two portions of this test. I know this article is mainly about GPS performance, but I would be remiss not to mention this impressive outcome.
Ultimately, this comparison has left me feeling downright cheery about the state of modern smartwatch fitness tracking, with each device performing incredibly well across the board.
Which begs the question: Can the Google Pixel Watch 5 keep up with the pricier Apple Watch Ultra 3 when it comes to logging outdoor workouts using onboard GPS in tricky environments? I’d say the answer is a resounding yes.
Which of these two smartwatches would you be more likely to use to track an outdoor workout? Let me know in the poll below.
