It's really common among runners and I've been a sufferer of it in the past. It's usually caused from an inbalance in your musles.... usually from the outter quad being stronger than your inner quad. It can be exascerbated by not stretching, which is most athlete's problem.... Stretch your quad and your IT band a ton. If you still have pain after a while, go see a doc. They will put you in physical therapy or suggest excersises to strengthen your inner quad, and they will tell you to stretch stretch stretch. So many injuries can be reduced or prevented by stretching :)
