We鈥檝e reviewed Apple watches before, and, in the past, have always told endurance athletes, “It鈥檚 a nice watch, but it鈥檚 not really for what you do.鈥 That’s especially true for those, like triathletes, who train every day, usually twice per day, and have a particular affinity for data, 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 have left something to be desired. And the battery life鈥攐h the battery life!
But now, with the release of their 鈥渁dventure-focused鈥 Apple Watch Ultra, Apple has鈥攆or better or for worse鈥攖hrown its hat in the endurance sports ring with the big boys. I wore the watch for a week of workouts鈥攔unning, cycling, and swimming once or twice a day鈥攑lus during a mini-triathlon to see how it holds up to real-world endurance use. Here’s what鈥檚 new, what I liked as I spent hours using it, what I didn鈥檛 like, and my conclusions.
Apple Watch Ultra: What鈥檚 New
Before I get into the specifics that make the Apple Watch Ultra an endurance/outdoor contender, let鈥檚 quickly take a look at what鈥檚 new:
- Increased battery life 鈥 Though Apple advertises 36 hours of smartwatch use, I found that even with workouts once or twice per day, I got three days between charges with all functions on (that’s 72 hours, twice the promised duration). They鈥檝e also told us that, using overall low-power mode, there’s enough GPS-on workout time to do a long-distance triathlon鈥攚hich I haven鈥檛 had a chance to test. 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. 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. This low-power workout聽mode will give even more training/racing time, but with fewer GPS and heart-rate data points.

- New case 鈥撀The updated Apple Watch Ultra case is 49mm and has a raised lip around the screen鈥攁s opposed to the rounded screen on previous models鈥攁nd a bigger digital crown.

- New 鈥淎ction鈥 button 鈥撀On the left of the case, Apple has added a new 鈥渁ction button鈥 that can be assigned to various tasks like a quick workout start, a quick stopwatch start, and various actions within workouts鈥攄epending on the workout profile.

- 鈥淧recision Start鈥鈥 This one is a little weird, but Apple (finally, finally) has a selectable mode that allows you to actually start a workout when you hit start or press the action button, as opposed to its maddening 鈥3鈥2鈥1鈥 countdown.
- Better sound 鈥 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 鈥 Though many of these updates may end up on other watches, new workout features like triathlon (which we鈥檒l dig into below), multisport (for bricks and nonstandard swim/bike/run events), and automatic track detection (coming soon) are huge for endurance athletes. In more general updates, Apple has included compass waypoints and backtracking, as well as a new 鈥淪iren鈥 alarm system and a host of diving functions we won鈥檛 get into here.
- LTE 鈥 Ok, this isn鈥檛 new, but it鈥檚 included on the Watch Ultra, and unlike previous iterations, you don鈥檛 have a choice. Apple says 18 hours of 鈥渁ll-day LTE,鈥 but that鈥檚 just for walking around. For working out, it鈥檚 substantially less. Apple didn鈥檛 have an exact figure, but they did say that the low power mode required to do an iron-distance triathlon would mean substantially fewer 鈥渃heck-ins鈥 with LTE. So yes, you could do an event and be tracked if you wanted (with the 鈥淔ind My鈥 function), but it wouldn鈥檛 necessarily be effective in low power mode for an Ironman.
Apple Watch Ultra: What We Like
As noted before, the Apple Watch series was always a bit frustrating for athletes鈥攖he super limiting battery life meant you had to charge it pretty much every night, and you couldn鈥檛 go on super long rides, or adventures, or race long-course tri or ultraruns 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鈥檙e looking at a smartwatch that can effectively handle nearly 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鈥檚 not just looks鈥攖he raised lip of the case protects the precious screen better than previous models by a ton. It鈥檚 also safe to say that the 鈥淧recision Start鈥 function and 鈥淎ction鈥 buttons are both things that pretty much every other smartwatch ever made already has, but both were gaps missing in Apple鈥檚 exhaustive function quiver.
With all of this combined, the Apple Watch Ultra is a solid watch for anyone training for a triathlon or a marathon or really any other endurance sports activity鈥攔egardless of distance. 国产吃瓜黑料 of training, Apple鈥檚 鈥渓ifestyle functions鈥濃攖hings like text messaging, weather, music, third-party apps, contactless payment, and (way, way) more鈥攁re 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鈥攏o one is even remotely trying to do this stuff, except for Apple. It’s also a decent (yes, just decent, more on that below) outdoor adventure watch.
Also, let鈥檚 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聽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鈥檚 not nothing.
Apple Watch Ultra: What Could Be Better
Many of the 鈥渙utdoor鈥 functions like navigation and mapping are still 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鈥攚hile cool鈥攁ren鈥檛 exactly going to save your life in the backcountry. The battery is better, for sure, but to consider this a multi-day hiking and backpacking watch over something more expedition-worthy is reckless at best. If you鈥檙e with a group of friends backpacking for a week, it鈥檚 probably not a bad choice, but if you鈥檙e doing a solo multi-day adventure or tackling an unsupported fastest known time (FKT), I wouldn鈥檛 count on the Ultra as your only navigational tool, like you could for other upper-end adventure watches like the Coros Vertix 2 or the Garmin Fenix 7/Enduro line.
In terms of more workout-specific capabilities, the battery life (finally) brings the Apple Watch into the realm of long endurance athletes like triathletes and ultra runners, but it still lacks some of the data power that both groups might really need. Triathletes should be encouraged that this is a watch they can finally do a full Ironman with (and all of the related Ironman training), but many serious long-course triathletes might be frustrated by the lack of native cycling power connectivity. The multisport crew might also 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 for the ultra/trail running set, 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.
Finally, there鈥檚 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聽a lot of smartwatch in the endurance/adventure realm鈥攆or 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鈥檙e still on another level.
Apple Watch Ultra: For Triathletes
The best part of the Apple Watch Ultra? That triathletes, especially long-course triathletes, finally have a valid choice in the Apple lineup. Assuming you鈥檙e not interested in cycling power connectivity (most triathletes probably use a cycling computer for that), and the fact that there are no open-water distance alerts (bummer), this new watch not only goes the distance in battery life, but it has something special, just for us: Automatic triathlon transitions.
Yes, Wahoo already scooped Apple with their own automatic transition function that can tell you鈥檙e going from swim to transition to bike to transition to run鈥攁nd mark each one鈥攂ut Apple鈥檚 new Ultra Watch actually does it better. In our tests against the Wahoo Rival, the Ultra outperformed the Rival in accuracy between transitions every time. (Note: The Ultra also does manual transitions with the action button, as well.) Though you can鈥檛 go back and edit your transitions like you can in the Wahoo app and 鈥渇ix鈥 any mistakes in marking transitions, the Ultra did a fantastic job of knowing when I went from sport to sport to sport.
The addition of a 鈥渞oom鈥 with various multisport configurations鈥攖hings like run-bike-run, swim-run-swim, etc.鈥攊s also a great addition to the Apple Watch OS ecosystem, as you can finally do bricks or nonstandard multisport events, with just a little bit of preplanning.

On the note of workouts, the Apple Watch Ultra does have some cool built-in workouts that you can select when you鈥檙e feeling uninspired by your training program, and of course you can create and edit your own workouts on watch鈥攚ithout the need for an app. Apple also says there will be a 鈥渢rack detection鈥 feature coming soon that will actually recognize鈥攙ia Apple Maps data鈥攖hat you鈥檙e in proximity to a track (U.S. only), and prompt you if you鈥檙e going to be running on it. If so, you鈥檒l choose a lane, and it鈥檒l 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鈥檙e near a track. For better or for worse, it鈥檚 a reminder that the Apple Watch Ultra is paying (very close) attention to you.
Conclusions
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鈥攂asically most things a smartphone can do now. They also let you go for casual workouts and track your 鈥渇itness鈥 (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鈥攆rom 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 鈥渨orkout watch鈥 for serious swims, rides, runs, hiking, and backpacking, 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鈥檙e dangerously close. For $800, you鈥檙e still not playing in the same sandbox as an $800 Garmin or Coros watch, 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鈥檛 core issues鈥擨 can鈥檛 imagine it鈥檇 be a tough lift to get offline mapping, especially given that the storage is already there (32 gigabytes). It also doesn鈥檛 seem incomprehensible that Apple could somehow get cycling power in the workout app via Bluetooth or add an average lap running power data field.
Apple has proven that they do understand the multisport athlete with the Ultra. They nailed something really complex (the auto transition mode), corrected something basic (鈥減recision timing鈥), and spent real money and time on something tough (the battery) that signals that endurance athletes are important to them. Having the exhaustive multisport 鈥渞oom鈥 goes a long way as well.
Is this the watch that replaces all of your watches? It very well could be.
