Syncing to Facebook like Runmeter App

I have the Runmeter app because I like to track my running, calories, distance, etc. I'm more of an outdoors runner so my question is and I'm sure Apple hasn't made it available yet but is there a way to "share" your runs and information to facebook? If not, Apple, you need to look at the Runmeter app, please make it have the features e.g. "sharing" to Facebook AND compete against friends or people that have the Apple iWatch. Maybe want to look at the NikeFuel and the Fitbit. Need to get on their level, I feel like Apple iWatch customers are behind the ball. Thanks!
