This also makes it useful for tracking sleep. In low power mode you can get up to 38 hours. For sessions that run long, it can handle up to eight hours of outdoor running with a heart rate monitor and GPS enabled.
Durability has also been improved. The aluminum models now feature tougher Ion-X glass with significantly higher scratch resistance, thanks to a new ceramic coating bonded at an atomic level. This makes the watch better suited for daily runs, crowded race environments, and unpredictable weather. Titanium variants continue to use sapphire crystal for maximum protection.

It makes it easier to stay consistent, recover smarter, and get you ready for that long run. With insights from professional athletes, let's take a look at how the Apple Watch experience has helped in enhancing their routine.
Diya Nayar, who is a Nike Athlete & Marathon Runner, has shared, "Having run the Mumbai Marathon since 2015, I’ve learned that running strong is as much about restraint as it is effort—especially in the final week. I focus on sleep, hydration, and arriving at the start line fresh, calm, and confident, rather than chasing last-minute fitness. On race day, controlled pacing, early fueling, and respecting the conditions are what make the difference over the second half of the race.
I’ve been using the Apple Watch for 9 years, and this year for the half marathon in Mumbai, my Apple Watch Ultra 3 helps me stay disciplined with my effort. I rely on pace and heart rate zones to manage intensity through the early kilometers and avoid overreaching in the humidity. Features like precise GPS tracking and custom alerts allow me to stay focused on the run itself—fueling, hydrating, and maintaining rhythm—rather than constantly checking my watch. And to help carry me through the distance, I always have my AirPods plugged in to give me that extra pump!
Post-race, I use recovery metrics such as heart rate recovery, sleep, and training load to understand how my body has responded and to guide my recovery over the following days. For me, performance is not just about how fast you run on race day, but how well you recover and continue to train consistently over the long term. The finish line is not the end, but just the beginning."
