I'm returning my SS in favor of a Sport. I found the screen on the SS to be too reflective in bright sunlight -- and literally unreadable when wearing my prescription sunglasses in direct sunlight. Some reports suggest the Sports screen is less reflective. The other problem I had with the SS for outdoor sports use is that the touch screen didn't work very well in sweaty conditions. That may not change much with the Sport. We'll see. I'm not convinced that even the Sports version will prove all that good for running. I'm not too hard core of a runner -- I run several half marathons a year, but my weekly total isn't usually more than 15 miles. But even as a recreational runner, I find the built-in workout app very limited in terms of its metrics. And, at least until native 3rd-party apps arrive, the other running apps don't get you use of the heart monitor. They are literally just remote controls over the apps running on the phone. Still, I want to like the Apple Watch -- so I'm going to give it a another try. Personally, I prefer Runkeeper out of the running apps. Garmin has just announced a new GPS watch -- the Forerunner 225 -- with wrist-based heart monitoring (developed by Mio) for $299. It's shipping later this month. That looks like being a far more capable running watch (and it also doubles as an activity tracker with step counting, etc.). But it's not as suitable for everyday wear and, obviously, it doesn't have all the other features of the Apple Watch. Anyway, the main point of this post is to suggest that runners and the like think twice before going with the sapphire screen.
