Sure, we’ve reviewed Apple watches before. Oftentimes it’s simply as a service to endurance athletes who might think about buying one, so we can just say, “It’s a nice watch, but it’s not really for what you do.” Especially those of us who train every day, sometimes twice per day, and have a particular affinity for data and accuracy and workout organization. Apple watches have great apps, beautiful screens, and the best touchscreens in the game, but their built-in workout profiles and post-data analysis leave something to be desired. And the battery life—oh the battery life! But with the latest “adventure-focused” Apple Watch Ultra, now—for better or for worse—Apple has its hat in the endurance sport’s ring with the big boys.

First, we’ll look at what’s new on the Apple Watch Ultra, talk about what we liked as we’ve spent hours using it, what we didn’t like, and then dive into the endurance sports specifics before giving our conclusions and some competitive analysis. Let’s see how it fares:

Apple Watch Ultra: What’s New

Before we get into the specifics that make the Apple Watch Ultra an endurance/outdoor contender, let’s quickly take a look at what’s new:

  • Increased battery life – Though Apple advertises 36 hours of smartwatch use, we found that even with workouts once or twice per day, we got three days between charges with all functions on. They’ve also told us that with overall low-power mode, there’s enough time of GPS-on working out (which we haven’t had a chance to do) to do a long-distance ultra. And in overall low-power mode, you lose no resolution for GPS or heart rate. Better yet, the Ultra will soon have a low-power workout mode that gives you 60 hours of smartphone time with 15 hours of working out, though less GPS and heart rate resolution. The overall low-power mode reduces the frequency of smartphone “check ins,” disables the always-on display, and a few other non-essential background tasks without lessening the resolution of heart rate or GPS while working out. The low-power workout mode will give even more training/racing time, but with fewer GPS and heart-rate data points.
  • New case – The updates Apple Watch Ultra case is 49mm with a raised lip around the screen—as opposed to the rounded screen on previous models—and a bigger digital crown.
  • New “Action” button – On the left of the case, Apple has added a new “action button” that can be assigned to various tasks like a quick workout start, a quick stopwatch start, and various actions within workouts—depending on the workout profile.
  • “Precision Start”– This one is a little weird, but Apple (finally) has a selectable mode that allows you to actually start a workout when you hit start as opposed to its maddening “3…2…1” countdown.
  • Better sound – Though not exactly a sports-related feature, the Apple Watch Ultra has a three-microphone array that helps reduce wind noise outdoors by self-selecting a mic based on wind direction. Apple has also installed a dual speaker system (yes, on a watch) that is substantially louder than previous watches.
  • Updates to watchOS 9 – Though many of these updates may end up on other watches, new workout features like automatic track detection (coming soon), multisport (for nonstandard swim/bike/run events), and triathalon are huge for endurance athletes. In more general updates, Apple has included compass waypoints and backtracking, as well as a new “Siren” alarm system and a host of diving functions we won’t get into here.
  • LTE – Ok, this isn’t new, but it’s included on the Watch Ultra, and unlike previous iterations, you don’t have a choice. Apple says 18 hours of “all-day LTE,” but that’s just for walking around. For working out, it’s substantially less. Apple didn’t have an exact figure, but they did say that the low power mode required for ultra distance events would mean substantially fewer “check-ins” with LTE. So yes, you could do an event and be tracked if you wanted (with the “Find My” function, but it wouldn’t necessarily be effective in low power mode for a trail race.

Apple Watch Ultra: What We Like

As we noted before, the Apple Watch series was always a bit frustrating for athletes—the super limiting battery life meant you had to charge it pretty much every night, and you couldn’t go on super long runs or adventures or race almost any ultras with it. Even if you loved everything else about the Apple Watch, that was always a deal breaker. The good news is that with the increased battery life and low-power options, you’re looking at a smartwatch that can effectively handle any workout, event, or outdoor adventure that you could throw at it. Apple also teased a low-power workout mode that would give additional battery life, but with reduced resolution of GPS and heart-rate readings coming soon.

Battery life aside, the more robust build of the Apple Watch Ultra makes it feel less like a piece of fine art and more like a tool for training. And it’s not just looks—the raised lip of the case protects the precious screen better than previous models by a ton. It’s also safe to say that the “Precision Start” function and “Action” buttons are both things that pretty much every other smartwatch ever made already has, but both were gaps missing in Apple’s exhaustive function quiver.

With all of this combined, the Apple Watch Ultra is not only a decent (yes, just decent, more on that below) outdoor adventure watch, but it’s actually a good watch for anyone training for endurance sports—regardless of distance. Outside of training, Apple’s “lifestyle functions”—things like text messaging, weather, music, third-party apps, contactless payment, and (way way) more—are basically unparalleled. Yes, Fitbit has some fun stuff and a nice screen, but Apple is still lightyears ahead of any competitor when it comes to smartwatch power and integrations. As an example: The three-mic setup is nothing short of magic when making calls on the watch—no one is even remotely trying to do this stuff, except for Apple.

Also, let’s not forget that since the untimely demise of the Forerunner 945 LTE, this is one of the only full-function workout watches with legit battery and LTE connectivity. So if you like to go training (or racing!) untethered to your phone, like so many of us do, this is still one of the ONLY ways to stay in touch via LTE. That’s not nothing.

Apple Watch Ultra: What Could Be Better

While I won’t speak to the dive functions, I would say that many of the “outdoor” functions like navigation and mapping are still pretty on-grid if the Apple Watch Ultra is supposed to speak to the hardcore adventure set. The lack of offline mapping and navigation seems like nothing more than an oversight (or lack of a mapping partner, maybe), and the compass waypoints and retroactive backtracking—while cool—aren’t exactly going to save your life in the backcountry. The battery is better, for sure, but to consider this a 100 miler or backpacking watch over something more expedition-worthy is reckless at best. If you’re with a group of friends backpacking for a week, it’s probably not a bad choice, but if you’re doing a solo multi-day adventure or tackling and unsupported fastest known time (FKT), I wouldn’t count on the Ultra as your only navigational tool—like you could for some upper-end adventure watches (the Coros Vertix 2 or the Garmin Fenix 7/Enduro line, for instance).

In terms of more workout-specific capabilities, the battery life (finally) brings the Apple Watch into the realm of ultra runners, but it still lacks some of the data power they really need. Trail runners should be encouraged that this is a watch they can finally do an ultra with (and all of the related ultra training). The multisport crew might complain about a lack of open-water swimming distance alerts that pretty much all open-water ready smartwatches have right now. And while native running with power is a total game changer, given that currently only Polar and Coros have that built-in, serious runners might take issue with how inflexible the power metrics are in the workout screens. Yes, having average power and average three-second power is great (and the ability to move those metrics around), but lap power is sometimes just as important, if not more.

On the note of workouts, the Apple Watch Ultra does have some cool built-in workouts that you can select when you’re feeling uninspired by your training program, and of course you can create and edit your own workouts on watch—without the need for an app. Apple also says there will be a “track detection” feature coming soon that will actually recognize—via satellite imagery—that you’re in proximity to a track (U.S. only), and prompt you if you’re going to be running on it. If so, you’ll choose a lane, and it’ll snap the GPS tracking and distances to that track. While other brands like Garmin and Coros have something similar, no one can automatically detect that you’re near a track. For better or for worse, it’s a reminder that the Apple Watch Ultra is paying (very close) attention to you.

Finally, there’s the Gucci-patterned elephant in the room: The price. Sometimes it feels like Apple gets a bit of a pass on pricepoint because it has SO MANY great lifestyle integrations and really cutting-edge hardware, but because Apple wants to play with the long-distance training/adventure crowd now, they need to stand and be compared to other smartwatches in that world (see our competitive comparison below). Eight-hundred dollars gets you a lot of smartwatch in the endurance/adventure realm—for instance the Garmin Fenix 7 or Forerunner 955 series or the Coros Vertix 2. All of those watches have some very very robust training modes, loads of customizable sport functions, navigation, and insane battery life. No, none have a beautiful screen, smartphone integrations, or LTE like the Apple Watch Ultra, but in terms of working out/navigating the outdoors, they’re still on another level.


There’s so much to cover in this watch, a reviewer could write a book, but the easiest thing to do is break the new Apple Watch Ultra down into what an Apple Watch has been before, and what this latest version is hoping to be. In the past, Apple watches have been a great lifestyle smartwatch that integrates incredibly with the Apple ecosystem. They play music send and receive texts, check emails—basically most things a smartphone can do now. They also let you go for casual workouts and track your “fitness” (lowercase) as you went. The Ultra still has all of that. Now, with the Ultra, Apple wants to be considered an endurance sports/adventure outdoors player up against the watches we used to buy to supplement our Apple Watch purchases—from brands like Coros and Garmin and Polar.

Now, instead of having your Apple Watch for going to the office or going out at night, and your “workout watch” for serious runs, backpacking, and outdoor adventure, Apple wants to be all of these things: Leave your Garmin at home, let it die. Does Apple fully pull this off? Not quite, but they’re dangerously close. For $800, you’re still not playing in the same sandbox as $800 Garmin or Coros watches, but if this watch was $500 (with LTE), those brands would be sweating big time. Even so, the issues we have with the Apple Watch Ultra aren’t core issues—I can’t imagine it’d be a tough lift to get offline mapping, especially given that the storage is already there (32gb by the way). It also doesn’t seem incomprehensible that Apple could somehow add an average lap running power data field.

Is this the watch that replaces all of your watches? It very well could be.
