Why do you need to run without a phone? Phones aren't that heavy and devices can be significantly cheaper and smaller if they don't need a GPS chip and music storage (smaller battery).

I stopped using my Garmin watch since I have a fitbit charge and find that measurements via phone are surprisingly accurate. In cities, pure GPS watches often lose signal (buildings, tunnels), phones can track much more accurately there.

I use my Garmin because I track heartrate when running and the Charge HR - whilst surprisingly accurate for step counting and distance and resting HR - is woeful when trying to track HR during exercise.

(Also for cycling with a variety of ANT+ sensors.)

Where do you keep your phone when you run? The only solution is strap it onto the arm, but I don't like that. It feels like a hindrance.
