I’ve said it before and I’ll say it again — the Apple Watch Ultra is the best Apple Watch to buy if you’re serious about running. From the watchOS 9 updates that allow you to build tempo sessions and recognize when you get to a running track, to the all-important action button that allows you to pause your run without taking your gloves off. I’ve run with the Apple Watch Ultra for a year now, and it’s a great gadget, but it hasn’t truly replaced my Garmin watch.
