According to a study from the University of Otago in New Zealand, one bout of high intensity heavy resistance exercises decreased running economy for up to eight hours. This means if you lift weights before you run, your performance could suffer. It's better to schedule weight training after an easy run, or the day before a run. Just don't do a hard run and resistance training on the same day; this could increase the chance of injury.
