Best Smartwatch for Running-Apple Watch Series 2

Apple Watch Series 2 running watch

Apple Watch Series 2

The Series 2 (not the Apple Watch 2) is a sportier smartwatch than its predecessor and that's because it's finally thrown built-in GPS into the mix. That means you can track runs (distance pace and speed) as well as cycling sessions.

While you'll want to opt for third-party apps (Workout is still data-light for runners), the heart rate sensor stood up well to the rigours of testing. It's far from perfect, but still capable of returning useful data, training within zones, and getting feedback on HIIT sessions.

The Series 2 also comes in a new Nike+ edition, which adds a perforated rubber strap and comes with custom software and watch faces. It'll also provide coaching plans to get the most out of your running sessions.
