Create interval workouts for Apple Watch
One of the features that will keep me tethered to Garmin watches and their web interface (Garmin Connect) is their workout creation and playback. As a serious runner, it would be great to use Strava and my Apple Watch to create and run interval workouts. When I'm running I want to be focussing on my run, not trying to keep track of my interval workout in my head. I imagine many athletes would find a feature like this helpful and it would help establish Strava not just as a tracking app, but as a training app as well. And being able to make workouts that you have created public seems like it would be a great new social component to Stravas endeavors.
