Most Apple Watches are excellent for logging training runs, but the Apple Watch Ultra and Apple Watch Ultra 2 are uniquely suited among their contemporaries for long-distance runs like marathons.
The batteries last for twice the amount of time as a regular Apple Watch, the precision dual-frequency GPS systems are more accurate to ensure you get exact distance measurements, and the additional Action button allows you to operate the watch without using the touch-screen, essential if you’re wearing gloves or dealing with lots of sweat.
