Should I stretch before a run?

There are various thoughts behind whether one needs to stretch before a run. Most recent research has shown no true benefit to static stretching prior to a run.  Individuals may actually cause more injury from static stretching if they over stretch without warming up. Dynamic stretching, such as skipping or hopping, may provide more benefit as it helps increase blood flow to the muscles and allows you to work through your range of motion prior to your run. 
It seems that stretching before a run may depend on your established habits. Simply put, researchers say that if you regularly stretch before you run, continue doing so, but if you don't regularly stretch, you may be better off not starting. The study, performed by Daniel Pereles, MD, an orthopedic surgeon in Potomac, Maryland, found that runners who stretched but who switched to a nonstretching group had a 23% increase in injuries. The nonstretchers who began stretching had a 22% increase in injuries.

This research is preliminary, and more study needs to be done on stretching, but these results may support what you already do.
