Apple has unveiled the Apple Watch Ultra 4, which not only brings improved physical attributes but also introduces a variety of training features aimed at enhancing the running experience. A particularly notable addition is the pacer function, which assists runners in maintaining their target pace. This feature is accompanied by an action button that is especially useful when users’ hands are too sweaty for a touchscreen, underscoring Apple’s dedication to practical design and user satisfaction.
Having tested the Ultra 4 for several weeks, I was genuinely impressed by the substantial boost in GPS accuracy that the updated Apple Watch Ultra series delivers. The device’s dual-band GPS tracking offers some of the most precise tracking capabilities available currently, complemented by a satellite configuration option that is crucial for outdoor adventures.

From urban settings to outdoor trails
The Ultra 4 distinguishes itself as one of the most adaptable watches on the market, providing accurate tracking even on rubberized tracks and accommodating up to two days of ultramarathon recording. With its dual-band GPS tracking, the Ultra 4 ranks among the leading performance watches, offering outstanding activity monitoring.
Its battery life allows for 45 hours of activity tracking and 84 hours in low-power mode, making it the longest-lasting Apple Watch to date. For those who push their limits, a rapid 15-minute charge can yield up to 18 hours of usage. Initially, I had concerns about its battery life in comparison to other models I’ve used, especially since I tend to forget to charge my devices. However, during my hectic mornings, a mere five-minute charge provided several hours of battery life, which I found to be extremely convenient.
The Ultra 4’s design places a strong emphasis on durability. It sports a sapphire screen and a titanium case, and I challenge anyone to attempt to damage it. Only diamonds can scratch the sapphire layer. No matter the terrain, I foresee no issues from accidental bumps against rocks while traversing trails.
Weighing 63 g, it might feel heavy to some, but it actually offers a very comfortable fit on the wrist. Compared to other rugged watches available, it is relatively lightweight.
Optimizing training
The training features were where I found the most enjoyment, allowing me to engage with my workouts as if I were a character in a video game. The Ultra 4’s new health sensor delivers the most comprehensive and accurate heart rate monitoring among wearable devices, based on internal comparisons with other brands. This advanced system introduces new and enhanced training options, including pacer (my personal favorite), readiness evaluation, and customizable workouts.
I favor the pacer feature because I often lose focus while running, which can lead to inconsistencies in my pace. The watch helps keep me aligned with my target time, whether I’m taking it easy or pushing myself harder. Setting my pacing strategy is straightforward; for instance, if I plan to complete a 10 km easy run at a pace of 5:15/km, I simply input that information, and the watch ensures I stay on course. It alerts me if I stray too far ahead or lag behind my pace, tracking my distance in both directions. Fortunately, it vibrates only once per alert, so I won’t be overwhelmed with notifications if I start to fall behind.
The training readiness feature is another outstanding addition to the Apple Watch. It evaluates how you perceive the difficulty of a run—whether it feels manageable or challenging—while also comparing health metrics such as heart rate variability (HRV) and sleep score to suggest whether to ease up or push further. While being in tune with your body is crucial, this feature can provide valuable insights before heading out for a run.
Prioritizing safety
For increased safety, the watch can connect to a satellite for the most reliable location tracking. The demonstration is entertaining as you position the watch to establish a satellite link, but it is reassuring to know that in the event of a serious fall or accident, the device can automatically contact local emergency services. There are prompts available to cancel this feature, allowing you to bypass it if necessary. However, should you be unable to respond, this function could prove to be lifesaving.
The Check In feature also significantly enhances safety. The watch will automatically notify a designated contact when you arrive at a specified destination. For example, when running after dark, simply initiate a “Check In,” and it will alert your chosen individual once your run concludes.
Final thoughts
One of the most attractive aspects of the Ultra 4 is that I have only begun to explore its functionalities in this review. The watch encompasses numerous additional features to discover, including sound recognition and a more advanced health app. Over the past few weeks, it has been enjoyable to delve into its functionalities, and even as someone who typically does not consider myself data-driven, I find myself exploring my statistics and personalizing my workouts.
The Ultra 4 represents a significant leap for Apple in the fields of sports and health tracking. While there is always room for improvement in battery life, the quick charging feature mitigates this concern. For those planning to run for over 45 consecutive hours, I commend your dedication, though I doubt many would find that a reasonable challenge.
