Oceanside (2012)

Oceanside is about a young man living in Southern California, straight out of college, with no idea what his responsibilities are - so he goes on lots of long distance runs to clear his head. He meets a pretty girl at the beach and they become friends, just as all his other friendships start to fall apart as people change. And this new friendship is more complicated than he thought it'd be, because he's falling in love, and she already has a boyfriend.
