My fiancee is a runner and I recently purchased her a Garmin GPS watch as a gift. I had originally planned to buy a FitBit, but they're just not meant for the same thing as the Garmin watch. The Garmin is useful when you are actually running to figure out your pace, distance, etc. The FitBit is more of a logging device and you don't really look at it while running. The FitBit doesn't have a screen, and I'm pretty sure it doesn't have a GPS.
